What type of AI tool
are you looking for?

Solheim AI is a paid, EU-hosted service that rents private large language model (LLM) instances rather than metering tokens. Each project maps to one "virtual private LLM" (VPL): a dedicated endpoint and API key whose capacity is set by two dials — the number of concurrent in-flight requests (instances) and the context window each request receives. Inside that purchased size, customers can run as much as they like, with no rolling usage window, no reset timer, and no per-token overage billing; requests beyond the instance count queue instead of returning 429 errors. Pricing is a flat monthly fee, with the published entry point at EUR 15/month for one instance and a 64k context window, before VAT. The service exposes an OpenAI-compatible API, so existing tooling and SDKs — editors, coding agents, and custom backends using a base URL plus key — can point at the endpoint without code changes. Available open-weight models include Qwen3.6-35B-A3B (mixture-of-experts, 256K context, Apache 2.0), Qwen3.8-27B (dense, 256K context, Apache 2.0) and DeepSeek V4 Flash (256K context, MIT), with models pinned per instance and swappable by changing one string. Customers can also request additional open-weight models to be added to the library. Sovereignty is presented as an architectural property: GPUs run at EU-owned providers in EU datacenters with no US hyperscaler in the serving path, prompts are not used as training data, and requests never leave the region. Larger configurations, including dedicated GPUs or MIG slices with 256K windows, private networking, signed DPAs and invoiced billing, are offered as an enterprise tier. A separate unlimited coding plan is marketed for coding-agent users.

BookletAI's PDF to Booklet is a browser-based AI tool that converts PDF content into redesigned A4 booklet pages. According to the product page, the AI reads the source content, restructures sections, adds illustrations, and applies a designed booklet layout rather than simply paginating the original PDF. The tool is part of the broader BookletAI suite, which includes related generators for magazines, storybooks, cookbooks, portfolios, catalogs, brochures, lookbooks, brand books, newsletters, employee handbooks, ebooks, reports, yearbooks, manuals, and worksheets. The PDF-to-booklet workflow focuses on transforming existing PDF material into a more structured, illustrated booklet format. BookletAI presents the PDF to Booklet tool as free to start, with a sign-in and user work area for managing generated projects. The site is available in multiple languages and states that more than 27,000 booklets have been created, indicating a hosted SaaS product rather than a local desktop or open-source application.

Rankora is a paid, browser-based SEO and GEO (generative engine optimization) platform that bundles eight related tools into a single AI-assisted workspace. The suite covers AI keyword research, daily SERP and rank tracking, backlink intelligence, technical SEO auditing, competitor analysis, AI content optimization, a site crawler rated for sites up to roughly 100,000 pages, and AI visibility tracking for mentions and citations in AI search results. The vendor markets it as an action-oriented alternative to established SEO suites such as Ahrefs, with pricing starting at $29 per month and a free trial signup flow. The workflow is deliberately simplified: a user enters their own domain or a competitor's URL, and the platform crawls the page, pulls live Google data, and runs more than 36 technical checks at once. Rather than presenting raw data dumps, Rankora returns a prioritized fix list written in plain English and ordered by projected ranking impact. Results can then be re-tracked on a recurring basis, so the product pairs diagnostics with ongoing monitoring. The product positions itself as suitable for non-specialists as well as experienced practitioners, combining keyword discovery, ranking monitoring, link analysis, on-page content guidance, and site infrastructure checks in one subscription. Because it is delivered as a hosted web application, no installation, tracking script, or self-hosted infrastructure is required. Details on the underlying stack, data sources, crawl frequency limits, seat counts, and export capabilities are not fully documented in the material reviewed here, and specific technical claims should be verified directly with the vendor.

ImageGenerator is a free web-based AI image generator that turns text prompts and reference images into finished visuals. Users describe the subject, style, mood, lighting, colors, and composition, then pick an AI model, aspect ratio, and resolution before generating. The service also accepts uploaded images, which can be edited, transformed, or used as a starting point for variations. The workflow is organized around four steps: describe the idea, choose settings, optionally upload a reference image, and generate and refine. Multiple variations can be produced quickly so users can compare creative directions and download the version they prefer. Featured models include options such as Nano Banana 2 Lite, and generations are metered in credits. The homepage presents the tool as a fit for marketing campaign visuals, social media content, product concept exploration, blog and editorial illustrations, ad creatives, and presentation graphics. It emphasizes high-resolution output, precision controls, speed, and commercial usability, and states that user content is not used to train its models. Pricing is listed as Free, with a dedicated pricing page and a credit-based generation meter; specific plan tiers, model list, resolution limits, and licensing terms are not fully documented on the homepage.

Screenies is a paid AI-powered screenshot generator for App Store and Google Play listings. It lets users upload app screenshots, describe the app, and generate a cohesive set of store screenshots with benefit-focused headlines and a consistent visual style, while keeping the real app screens inside the design. Users can refine generated sets by editing headlines, reordering screenshots, swapping the app screen in a frame, and regenerating individual screenshots using credits. Screenies also supports localization by translating headlines for different App Store or Google Play locales while preserving the artwork and layout. Finished sets can be downloaded as PNGs sized for iPhone, iPad, Android phone, or Android tablet. The service offers one-time credit packs starting at $9 with no subscription required, and unused credits do not expire. Downloads are free, and App Store Connect and Google Play uploads are included with credit packs. Screenies also provides an MCP server integration for tools such as Claude, Codex, and Cursor. It targets iOS and Android app developers, indie founders, designers, and product teams that need polished store listings quickly.

LoRA AI Image Generator is a web-based tool hosted at loraai.pro for generating AI images and videos with LoRA (Low-Rank Adaptation) models. It provides a model directory where users can browse curated LoRA models, including base model information, trigger words, prompts, and example results. The site supports creating repeatable characters, styles, product photos, and AI influencer visuals, with dedicated pages for consistent characters, style LoRAs, product LoRAs, fashion models, clothing LoRAs, and video character consistency. Users can start from a prompt, a reference image, or a custom LoRA training workflow. The platform also advertises API workflows for generating images and videos, and a training flow for custom LoRAs. The homepage prominently lists both image and video generation, plus an editable LoRA AI image generator and curated examples for portraits, product visuals, posters, reference-image remixes, social creative, and concept art. Pricing is listed as Free, and the tool is accessed through a browser. Exact usage limits, supported base models, output licensing, and API details are not fully specified on the homepage.

Haiper AI is a web-based AI video generator accessible at haiperai.org. It turns text prompts, still images, and source clips into short-form video drafts. The service offers text-to-video, image-to-video, and text-to-image workflows through a credits-based multi-model generation interface. The homepage describes comparison of model behavior, credit cost visibility before generation, and generation history for returning to completed images and videos. It also provides task-specific generators for real estate photo to video, architecture render to video, interior design video, furniture video, product photo to video, car photo to video, jewelry video, and skincare product video, among other use cases. Haiper AI is positioned for creating motion drafts, product visuals, image edits, and higher-quality paid generations without requiring a heavy editing stack. A free pricing entry is listed in the catalog, while the homepage describes credits and paid generations for advanced model capabilities.

WearMeNow is an Italian B2B SaaS platform for fashion e-commerce, positioned as an "AI Fashion Commerce Platform" built primarily around Shopify. Its headline capability is multi-garment AI virtual try-on: shoppers can visualise complete outfits of up to six catalog items at once, and the try-on experience runs directly on product pages through a Shopify app embed, app block or widget after catalog synchronisation. The tool is developed by Spiralapp.it (Cirulli Riccardo), with a product and login site at dress.wearmenow.shop; the vendor explicitly distinguishes it from the unrelated consumer app "WearNow AR". Beyond try-on, WearMeNow bundles several adjacent AI marketing modules into a single platform. These include AI-generated model shoots that place catalog garments on generated, scene-set models, an AI Stylist that assembles complete outfits and recommendations from the merchant's own catalog, Social AI for creating and publishing social posts with performance analysis, and a SEO/GEO Intelligence dashboard covering on-page audits, canonical URL repair, llms.txt and geo.json files for AI crawlers, plus Google Search Console analytics. A voice commerce component is also advertised. The platform is sold as a subscription, with marketing pages referencing plans starting around EUR 49 per month; a separate "store from scratch" offering combines a native WearMeNow storefront with a setup fee and a monthly subscription. A live demo store at /allstore lets prospects test the multi-garment try-on before purchasing. Documentation pages reference privacy, DPA, trust and developer/API overview sections, with English versions under /en/. The exact technology stack, model providers and license terms are not disclosed on the homepage, and the catalog metadata lists no public source repository. Details of free-tier limits are also unspecified, so prospective users should verify current pricing and API availability directly with the vendor.

TurnVideo is a web-based AI video generator that offers text-to-video and image-to-video creation tools. According to its homepage, users can type a scene description and receive a cinematic shot, or animate a photo into a smooth video clip. The platform presents itself as an all-in-one generator for videos and images, with support for several named generative models, including Seedance 2.5, FLUX 3, MiniMax H3, Kling 3.0, Nano Banana Pro, Gemini Omni 1.1 Flash, and MiniMax H3 Max. It advertises a free start and a no-code browser workflow. The site lists dedicated tool pages for text-to-video and image-to-video, and indicates that start-and-end-frame control and a video extender are coming soon. Model-specific pages describe capabilities such as first-to-last-frame control and 3–10 second clips for Gemini Omni 1.1 Flash, and 5–15 second 768p clips with native audio for MiniMax H3 Max. These details reflect the homepage's descriptions and may change as third-party models are updated. Because TurnVideo aggregates multiple third-party AI models, its output quality, duration, resolution, audio support, and availability depend on the selected model and the provider's current terms. The homepage does not expose source code, license terms, or independent benchmark results, so users should verify commercial usage, content rights, and data handling policies before relying on it for production work.

SD AI Studio is an independent, browser-based AI video creation service built around the Seedance 2.5 video generation model. It generates cinematic video clips from either a text prompt or a reference image, and it supports first-frame/last-frame control as well as extending existing clips. The service advertises native synchronized audio, including dialogue and ambience, generated alongside the picture rather than added in a separate step. The product is presented as a "director workspace" rather than a single-button generator. Users set a creation mode, attach reference assets (images, video, or audio), write a creative direction prompt, choose camera language presets such as cinematic push, handheld follow, or product orbit, and then configure output parameters like duration, aspect ratio, quality, and bitrate. The homepage markets continuous takes of up to roughly 30 seconds and stable character or subject identity across shots. SD AI Studio is a paid, account-based web application with sign-in, billing, activity history, and preview features. The site states explicitly that it is an independent third-party service and is not affiliated with or endorsed by ByteDance, Dreamina, or the Seedance model team, meaning the underlying model is used or accessed by a separate operator. Because the product is delivered entirely through a hosted web interface, there is no local installation, SDK, or public repository documented on the homepage. Detailed technical specifications such as the hosting stack, licensing terms, and model weights are not published.

RemixViral is a web-based AI video creation and dubbing tool focused on short-form content. It can generate faceless Shorts from an idea or script, producing AI script, voice, visuals, and captions without requiring on-camera talent. It also supports dubbing videos the user has rights to use into 12 languages, with AI transcription, translation, voice replacement, and caption synchronization. The product includes a review-before-export workflow so users can check translation, audio, timing, and usage rights before publishing. It offers a free starter balance, monthly plans, and pay-as-you-go credit packs. Paid tiers advertise watermark-free 1080p exports and API access for automation. A viral database of analyzed videos is available for inspiration and remix research. RemixViral positions itself for creators and businesses that need scalable short-form video output. It combines faceless video generation and multilingual dubbing in a single cloud interface. Exact AI models, infrastructure details, and licensing terms for generated content are not fully specified on the homepage.

PaperBanana (Paper Banana) is a web-based academic illustration generator that converts research paper text, reference images, or rough sketches into publication-ready figures. It focuses specifically on scientific and technical visuals such as methodology pipeline diagrams, model architecture block diagrams, statistical plot panels, graphical abstracts, poster panels, and educational infographics, rather than general-purpose AI art. The product exposes several distinct entry points in its app: an Image-to-Image tool for generating figures from uploaded sketches, screenshots, or reference images; an AI Image Editor for revising and cleaning existing visuals with text instructions; and an AI Image Upscaler for improving resolution and clarity of low-quality drafts. Users can also start from a library of curated prompt templates covering common research figure patterns such as RAG pipelines, transformer architectures, benchmark plots, and sketch cleanup. A typical workflow begins with describing the desired figure or pasting paper context, optionally supplying reference material, then choosing a visual style. According to the homepage, sign-in is required before generation, free draft previews are provided to test an idea, and paid models are recommended when cleaner labels and more publication-ready output are needed. The site references Nano Banana and Nano Banana Pro as underlying image models. The positioning is explicitly aimed at researchers rather than generic AI image generation, emphasizing consistent labels, readable arrows, structured panels, and diagram conventions suitable for papers, talks, and posters.

BetterKids is a web-based educational application aimed at children and their families, marketed as an AI-powered platform for personalized learning. According to its homepage, it combines AI-driven learning tools with interactive stories, math games, and curated YouTube video recommendations inside a single app experience. The product positions itself around personalization, suggesting that learning content and stories are adapted to the individual child rather than delivered as a fixed curriculum. Alongside the child-facing features, the homepage references "school updates," indicating that the platform also intends to serve parents by keeping them informed about school-related activity. The site describes itself with keywords spanning education, kids, learning, parenting, school updates, stories, and math games, which suggests a broad early-learning focus covering literacy and storytelling as well as numeracy. Meta descriptions describe it as an "AI-powered educational platform with school updates, interactive stories, and personalized learning." Public information about the product is currently limited to the marketing homepage: there is no available GitHub repository, public documentation, or published pricing detail. As a result, details such as supported age ranges, curriculum coverage, underlying AI models, data-handling practices, and pricing tiers cannot be verified from the sources reviewed.

VayoVideo is an AI-powered platform for generating manga-style images, videos, and comics. It combines text-to-image, text-to-video, image-to-video, and editing tools into a single workflow, allowing users to create consistent characters, story panels, and animated scenes. The platform is designed to streamline content creation for manga, anime, and comic projects, from initial concept to final video. Users can start with a text prompt to generate manga characters and scenes, then animate the strongest frames into short videos. The studio includes tools for image editing, redrawing, style alignment, and music video creation. VayoVideo offers a free tier with credit-based usage and paid plans for additional features. The platform is web-based and requires no installation, making it accessible to creators of all skill levels. It is marketed as a no-waitlist solution for AI manga and video generation.

Pyratrend is an AI-powered product research and analytics platform built for dropshippers, white-label sellers and brand owners. It continuously monitors large volumes of Shopify stores, Facebook ad libraries, Google Trends data and Amazon listings to surface products that show signs of proven demand, aiming to help merchants find "winning" products that are already validated but not yet saturated. The product positions itself as a next-generation research dashboard rather than a simple trend list. A proprietary AI matching model cross-references signals from multiple sources, and the interface presents trending product candidates with associated ad creative counts and category-level demand indicators that update frequently. A dedicated agent, Agent Pyra, is offered as a conversational or assisted research layer alongside the standard trending-products view. Access is web-based and free to start: new users receive 30 research credits on sign-up without a credit card, and unregistered visitors can run a limited number of searches per day. Paid tiers are offered through a pricing page for heavier usage. Supporting material such as how-to guides, "scale blueprints" and insights articles is published on the site to help users act on the research output. Because the vendor does not publish a public GitHub repository or technical documentation, details about the underlying models, data sources' update frequency and data retention are not independently verifiable from the homepage alone.

Whizi is a paid, browser-based AI workspace that consolidates access to multiple frontier large language models and image generation models behind a single subscription. According to its homepage, the service provides access to OpenAI GPT models, Anthropic Claude (Sonnet and Opus), Google Gemini, and image generators such as Nano Banana, OpenAI GPT Image, and Flux 2 Pro. Whizi also advertises access to over 300 additional models including Moonshot, GLM, DeepSeek, Grok, Qwen, and Mistral, positioning itself as a model-agnostic hub rather than a single-vendor assistant. The product is organized around a chat workspace with features for comparing model outputs. A model comparison tool lets a user send one prompt to two models and read the answers side by side, and the site also offers a savings calculator that estimates the cost of separate AI subscriptions. The marketing material highlights use cases across research, software engineering, writing, data analysis, and creative production, with Gemini framed for large-document analysis and long context, GPT for reasoning and code generation, and Claude for drafting and long-context nuance. Whizi is commercial software with no stated free tier on its homepage; pricing pages and a registration flow are the primary entry points. The site claims more than 40,000 users and lists testimonials from accounting, general productivity, and everyday-assistant contexts. Because the company is an aggregator rather than a model developer, its performance, context limits, and availability depend on the upstream providers it resells or proxies.

Bica Nutrition is an AI-powered nutrition tracker and calorie counter that lets users log meals through chat or voice. It provides honest feedback and tracks calories, protein, carbs, fat, and other nutrients. The platform is designed to make food logging conversational and fast, with around 10 seconds per meal entry. Bica offers daily goals, AI-generated goal suggestions, and progress visualization. It can remember exact nutritional values for specific products when provided, otherwise estimates from descriptions. The tool supports Portuguese, English, and Spanish. It offers a free plan and paid tiers: Base at 4.99€/mo and Super at 9.99€/mo, with varying interaction limits and food storage capacities. Bica emphasizes habit building rather than just logging. It provides feedback when users overdo it, not only positive reinforcement. It is not a replacement for professional dietetic advice. Features include sharing daily summary images, tracking weekly habits, and monitoring macronutrients.

Qualtix is a web-based stock research platform that combines a rules-based quantitative scoring model with an AI-generated natural-language explanation layer. Users enter a ticker and receive three separate scores — Business Quality, Valuation, and Entry Timing — which are combined into a single overall verdict such as Strong Buy, Buy, or Hold. The company states that the model is driven by SEC filing data and is refreshed daily across more than 1,000 supported stocks. In addition to per-stock analysis, Qualtix offers a screener that ranks the covered universe by score, a portfolio view that scores existing holdings and flags positions worth reviewing, a portfolio builder for testing how a new ticker fits an existing mix, and a side-by-side comparison tool that scores two tickers on identical factors. An AI assistant referred to as an AI Coach answers questions grounded in the computed scores rather than overriding them. Qualtix publishes research on a regular cadence, including daily model rankings, weekly radar reports, and periodic performance reports. The site advertises backtested results from 2017 to 2025 claiming the Strong Buy portfolio beat the S&P 500 in eight of nine years, plus early paper-trading results, while repeatedly stating that the output is research only, that there is no brokerage connection, and that it does not constitute financial advice. Pricing details are not specified on the homepage beyond a free trial, and the platform is delivered entirely as a hosted service.

TreeMax is a free AI-powered plant care application for iOS and Android that positions itself as a bonsai and general plant doctor. Users photograph ailing leaves, pests, or discolored foliage, and the app's AI model returns an identification of the likely disease, pest infestation, or nutrient deficiency along with step-by-step treatment instructions. The company states that its AI output passes multi-layer botanical safety checks before treatment advice is surfaced. Beyond diagnosis, TreeMax functions as an ongoing care assistant. It generates species-specific watering, fertilizing, and repotting schedules, sends automated reminders, and factors local weather into its recommendations so growers know when to move plants indoors or delay watering. A conversational 'AI botanist' lets users ask free-form care questions by text or voice, and the assistant retains a per-plant history of past illnesses and treatments to personalize future advice. Supporting features target hobbyist record-keeping: a visual growth timeline with photo and note logging, a garden inventory that tracks soil, fertilizer, and tool consumption, and an expense tracker with charts for spending on pots, soil, and supplies. The homepage advertises more than 5,000 growers, 12,000 tracked plants, and 1,500 AI diagnoses, alongside a 4.8/5 App Store rating. A community feed allows users to share growth updates and treatment tips. TreeMax is published by DOGOO and distributed free of charge through the Google Play Store and Apple App Store. Smart garden IoT integration — connecting soil moisture sensors, auto-watering systems, and environmental monitors for automated, data-driven care — is listed as a coming-soon capability rather than a shipped feature.

SideTap is an open-source MIT tool that lets an LLM agent see and control a real iPhone from a Windows desktop over USB. It does not require a Mac, Xcode, jailbreak, Appium server, or paid Apple developer account; a free Apple ID is enough. The install script sets up Python, go-ios, and SideTap on Windows, then the viewer walks through one-time iOS Developer Mode and WebDriverAgent sideloading steps. SideTap drives the phone through WebDriverAgent, so agents read the actual UI element tree with exact buttons, labels, and point coordinates rather than relying on OCR guesses. A Python harness exposes helper calls for tap, swipe, type, screen reads, and one-call flows like send_message, read_messages, and send_image. It also provides native MCP tools for agents such as Claude Code and Claude, plus a live viewer at around 34 fps with click-to-tap and drag-to-swipe controls. Safety and supervision features include a kill switch, live activity feed, and a prompt injection gate that pauses outgoing sends for approval after the agent has read the screen or messages. The gate bounds what an injected instruction can send, though the README states it does not bound what the agent can tap. SideTap also supports copying new camera roll photos and videos to a Windows folder over USB without iCloud.

Just The Gist is a free macOS application that converts long-form video and audio content — YouTube links, podcasts, lectures, meeting recordings and conference talks — into clean transcripts and short, structured summaries. It is distributed as a signed and notarized native SwiftUI app for Apple Silicon Macs (M1 or newer) running macOS 14 or later, and requires no account, subscription or API key to use. By default the entire pipeline runs on-device. Speech-to-text uses Whisper running locally on Apple Silicon — the developer cites support for roughly 100 languages and a transcription speed of about 2.8x realtime — and a built-in local language model is downloaded on first launch to generate summaries on the machine. Because of this local-first design, audio never leaves the user's computer. Cloud AI providers such as Anthropic, OpenAI and OpenRouter are supported as optional alternatives, and the app can also connect to any OpenAI-compatible local server, including Ollama and LM Studio. A 'Magic Copy' option hands users the transcript plus prompt for pasting into a cloud chatbot manually. Summaries are presented with a TL;DR section, key topics, and clickable timestamps that link back to the exact second in the source media. The app accepts YouTube URLs as well as local mp3, m4a, wav, mp4 and mov files, and transcript language and summary language can differ, so a German podcast can be summarized in English. A library view tracks videos, audio, starred items and in-progress transcriptions along with total transcribed hours. The tool is free with no locked features and is sustained by donations through Ko-fi, with a roughly monthly release-notes newsletter.

AlphaWeb is a cloud-based artificial intelligence platform positioned as a fully agentic AI system for serious ecommerce operators. It presents itself as a unified AI operating system for ecommerce, meant to help users launch and scale online businesses without relying on disconnected plugins, separate tools, or manual workflows. The platform is currently described as being in beta and available for early users. Through natural language instructions, AlphaWeb claims to build, run, test, and optimize ecommerce experiences for revenue and profit. It automates storefront creation, payment integration, and page design, with all assets described as built to convert. The platform also supports advanced commerce requirements such as combining one-time products with subscriptions, bundles, upgrades, upsells, and downsells, as well as custom checkout rules and pricing logic. AlphaWeb emphasizes flexibility by allowing users to describe desired business functionality and have the AI generate custom solutions, including interactive product configurators, 3D visualizers, calculators, and unique buying experiences. It also supports multi-currency and multi-language capabilities, making it suitable for businesses targeting international markets. However, detailed technical documentation and public pricing are limited at this time.

InterviewHack.ai is a free interview preparation platform that turns a single job posting link and the user's CV into a complete preparation dossier. It cross-references the company, the role, and the interviewers with the candidate's resume to generate likely questions and answers. The platform provides an ATS score for CV tailoring and identifies the exact keywords used by applicant tracking systems such as Workday, Greenhouse, and iCIMS. The service offers a live interview copilot as a Chrome extension. During real virtual interviews, the extension listens to the conversation and displays concise 3-4-word anchors from the user's own prepared material and CV within about a second after each question. The side panel is designed to be invisible when sharing the screen. After the interview, it gives a recap, improvement suggestions, and a quiz for reinforcement. For practice, users can rehearse on WhatsApp through voice-note interviews, including behavioral (STAR), technical, and salary negotiation scenarios, receiving word-by-word feedback and PDF session reports. The platform also provides daily job matches scored against the CV, tailored CV rewrites, cover letters, and recruiter messages. InterviewHack.ai is currently free and supports English and Spanish.

Doodlur is a free drawing idea generator designed to help hobby artists overcome creative block. It provides random drawing prompts across eight categories including nature, animals, fantasy, characters, objects, food, vehicles, and anime. The tool is entirely web-based and requires no account or installation, so users can generate an idea with a single click. Each prompt is paired with an AI-generated reference image in a consistent editorial illustration style, giving users a visual starting point before they begin to draw. The generator allows users to filter prompts by difficulty level: Easy, Medium, or Hard, making it suitable for quick warm-ups, children, everyday practice, or more challenging sessions. Every idea page includes step-by-step drawing tips. Saved ideas are stored in the browser without needing an account. The service is free; a Pro plan is planned to offer custom ideas, line art, and HD downloads, but the core generator remains free. Doodlur aims to reduce the time spent deciding what to draw and searching for reference material. By combining a text prompt with an AI reference image, the tool helps both beginners who struggle to visualize an abstract idea and experienced artists who want a composition starting point. All reference images are generated in a consistent style that does not imitate any living artist and pass both automated checks and human review.

Gotcha is a fully on-device AI copilot for Android developed by Samosa-AI. It turns natural language commands into real device actions across more than 100 built-in tools, from sending texts and making calls to controlling system settings, managing media, and automating screen interactions. It runs entirely on the phone and supports bring-your-own-model (BYOM) configuration with local or cloud endpoints, and new users receive free Samosa AI credits to test features. The app currently requires Android 11 or newer. The app includes two complementary modes: Monitor (40+ read-only tools for inspecting device state and screen context) and Operator (all 100+ tools for executing changes). Users can switch modes instantly and are notified through visual indicators—a blue ring indicates foreground reading, while an orange ring indicates background processing. Permission controls are structured across four tiers, from everyday operations to privileged access, and all actions are logged in an append-only audit log to keep users aware of what the assistant does. Gotcha also ships with a floating Assistive Ball, enabling push-to-talk voice activation from any screen. Voice calls allow the assistant to see your current screen and act on your behalf, such as searching the web for similar shirts while shopping online. The project provides a direct APK download via GitHub releases and includes documentation for safety permissions, setup, and broader customization.

Lodekeep is a hosted portable persistent memory service for AI assistants. It implements a Model Context Protocol (MCP) memory server so that ChatGPT, Claude, Grok, Gemini, Cursor, Claude Code, and other MCP clients can share one memory layer. Instead of storing isolated memories in each AI product, users can tell one assistant to remember a decision or preference and later have a different connected assistant recall it. The service provides a free tier, a live demo that does not require an account, and a simple setup path where compatible clients can be connected by pasting one URL or running one command in CLI tools. Lodekeep emphasizes user control and curation. Users can include or exclude project sources from recall with a tap, ensuring only chosen repositories or work streams feed the AI. It also offers personas—adjustable standards or 'rigor ladders' such as Enterprise Grade, Client-Ready, Startup MVP, and Research—that agents are asked to follow. Personas can be blended and given an intensity level, while a security floor prevents the selected standard from dropping below a user-defined minimum. Under the hood, Lodekeep performs semantic recall using OpenAI embeddings and vector search with keyword fallback. This means users can ask in natural language and retrieve relevant decisions, lessons, and context scoped to their own memory. The same memory is exposed through an MCP bridge and an API with scoped, revocable keys, making it suitable for always-on autonomous agents running on servers that may restart or switch models. Memorable context is restored after a restart, avoiding the need to re-establish what an agent was working on.

CalcBoxer is a free online platform offering a large collection of calculators for everyday and specialized tasks. According to its homepage, it includes 723 free calculators across 20 categories, ranging from construction, mathematics, physics, and finance to health, salary, motoring, date and time, IT, ecology, real estate, business, cooking, and games. Each calculator has its own page with the relevant formula, aiming to make the underlying calculations transparent and accessible. CalcBoxer supports a wide variety of practical uses. Users can compute a BMI or biometric screening, estimate mortgage or loan payments, convert units, plan construction materials, analyze business margins, or explore physics and math formulas. The site also includes newer categories such as AI regulation and agentic commerce cost estimates. Coverage includes both serious calculations and lighter interactive tools such as games and entertainment calculators. The platform is designed to be open to all users without requiring signup for regular use. It also offers embed options for webmasters who want to place free calculators on their own pages. Currency and unit conversions are provided, with the currency rate being entered manually by the user. Health and compliance calculators are clearly framed as estimates based on formulas rather than as professional diagnoses or legal advice. While the site presents a wide breadth of categories, each tool is relatively focused, typically solving a single formula or conversion. This makes CalcBoxer a convenient reference for quick calculations rather than a comprehensive analytic suite.

WrapScribe is a macOS dictation application that turns speech into clean, formatted text directly on your device. It uses Apple's speech recognition to transcribe audio locally, with no network upload, making it suitable for private and offline use. Users hold a customizable hotkey to start dictation, speak naturally, and release to have polished text appear at their cursor in any application. The app includes a rich feature set that goes beyond basic dictation, including offline meeting transcription, smart notes, and per-app writing styles. In addition to standard dictation, WrapScribe offers meeting tools that detect active calls and allow users to record two tracks (self and others) to generate transcripts and AI notes. The app also includes Snippets for expanding spoken trigger phrases, Dictionary for learning names and custom spellings, and Transforms to apply custom rewrite instructions like polishing or summarizing.

HAIEC is an evidence-bound AI assurance platform that lets organizations scan, attack-test, and prove the safety of consequential AI systems before they act. It connects source, identity, access, policy, permissions, evidence, and observed behavior to produce an AI Action & Access Map. This map shows what an AI system or agent can reach, what credentials it uses, what actions are technically possible, and what controls apply. HAIEC is applicable to AI applications, AI systems, AI agents, model/API integrations, automated AI workflows, and consequential agentic systems. HAIEC addresses the structural difference between permission and delegation. It asks five evidence questions: intention, policy, credentials, capability, and observed. Missing evidence remains UNKNOWN and is never silently treated as a pass. The platform maps evidence to recognized frameworks and regulations including SOC 2 AI controls, ISO 42001, EU AI Act, NIST AI RMF, NYC Local Law 144, Colorado AI Act, and OWASP Top 10 for LLM, though framework mapping is not the same as assurance. The platform follows a Define, Connect, Collect, Assure, Verify, and Monitor lifecycle. It supports developers, teams, assurance firms, and enterprises, with founder-led POC engagement for enterprise. Monitoring is bounded to supported runtime evidence sources, and evaluated scope is currently structured at the contract level, with structured scope binding under development.

Fius is an AI-powered coding assistant that offers both a command-line interface and a web-based platform. The tool is designed to help developers streamline their coding workflows by generating code, explaining snippets, debugging issues, and refactoring existing code using natural language prompts. Its dual-interface approach aims to make AI assistance accessible whether a user is working in a terminal or in a browser. The tool is freely available, though detailed documentation and feature specifications are sparse at the time of writing. The command-line interface enables developers to integrate Fius directly into their terminal-based processes, allowing for quick queries and automated assistance without leaving the editor. The web platform provides a more visual and interactive environment, which may benefit those who prefer a graphical interface or need to share context with teammates. While no official sources detail the full architecture, the existence of both interfaces suggests a flexible product that adapts to different developer preferences. However, a notable limitation is that the official homepage (fius.dev) was inaccessible during this analysis, returning a Cloudflare 522 error. As a result, the complete feature set, integration possibilities, and platform reliability could not be validated. Consequently, the information presented here relies on the short product description and may not capture the full capabilities of the tool.

AI4Kanban is a local-first project management board built specifically for AI coding agents. It starts with a rough product idea, reads the actual codebase and project memory, and automatically turns the idea into build-ready tasks with an explicit implementation order and dependency relationships. The tool coordinates work across independent coding agents in parallel, using mechanisms like git worktrees so that separate runs do not write the same files. Instead of requiring a human to supervise every step, AI4Kanban handles planning, follow-ups, and routine coordination itself. AI4Kanban only surfaces product decisions that genuinely need human judgment. When a choice is ambiguous, it presents a small set of options with a recommended default, letting the user decide before code is written. The platform also supports custom skills — such as creating UI mockups or running QA loops — to guide agents through the approach a team prefers. AI4Kanban is free and open source, available as a downloadable desktop application with a Kanban board UI and a CLI, and aims to be an AI project manager rather than just another task tracker.

ChronoCast AI is a free iPhone app by developer Erdem Gulen that turns photos of real places into narrated comics. Photograph a ruin, a street corner, a café, or a kitchen, and the app recognizes the location and proposes a one-line story context; the user can edit that sentence before generation. ChronoCast then renders four to six illustrated panels that attempt to keep the geometry, landmarks, and vantage point of the original photo recognizable while converting it to a chosen comic world. Four visual worlds are available: Socratic Anime, Future-Sketch, Noir, and Pet's-Eye View. Each has a corresponding narrator and point of view, and generation can be framed as history, a witness account, or a place speaking for itself. The app exposes its guesses as an editable sentence, where underlined words can be adjusted so the era, location, and narrator fit before images are drawn. ChronoCast also writes a character description and repeats it in each panel, reducing the common problem of characters changing appearance across frames. The result can be exported as a 1080x1920 vertical video with a slow cinematic camera movement and burned-in subtitles, intended for Reels, TikTok, or similar short-form platforms. No account or sign-up is required, and generated comics are stored on device rather than in a cloud library. The first comic is free; additional narrators, six-panel comics, and video export require ChronoCast Pro or a one-time in-app top-up. The app is listed for iPhone in the Photo & Video category, rated 9+, and is currently localized in English. The developer notes that all narratives are AI-generated fiction inspired by the photograph and not a verified historical record.
