Vismo
Vismo is a free AI-powered web application for generating math and science animations from plain-English descriptions. Users type a sentence such as "Show the unit circle with sin and cos as projections while the angle sweeps from 0 to 2π," choose an aspect ratio and voice, and Vismo produces a narrated video. The platform is designed for educators, students, and content creators who want 3Blue1Brown-style explainer animations without writing Python or installing Manim. Under the hood, Vismo uses AI to generate Manim Community Edition code, the same animation engine popularized by 3Blue1Brown. Before rendering, the scene is executed headlessly and every frame is measured to detect overlapping labels, cramped spacing, and cut-off formulas; these layout problems are repaired automatically. The final render can include AI voiceovers in nine languages using more than fifteen ElevenLabs voices, with exports available from 480p to 4K in MP4, GIF, or other formats and in 16:9, 9:16, or 1:1 aspect ratios. Vismo is positioned as a faster alternative to hand-writing Manim code, asking a chatbot for code, or using generic AI video generators. It targets teachers who need lesson visuals, students who want to understand formulas, and creators producing math and science content for social media. The service is free to start and includes a gallery of examples organized by topic such as calculus, geometry, physics, chemistry, and computer science.

Problem solved
Creating accurate math and science animations normally requires writing and debugging Manim/Python code, manually checking layouts, and adding narration separately. Vismo solves this by turning a single sentence into a narrated, frame-verified animation: AI writes the scene, every frame is executed and checked for overlapping or cut-off text, and the video is rendered with voiceover in multiple languages.
Use cases
- Generate a narrated unit circle animation showing sin and cos projections from a single sentence
- Create a 3Blue1Brown-style explainer video for a calculus lesson
- Produce vertical 9:16 math animations for TikTok or Instagram Reels
- Turn a physics concept like projectile motion into a narrated visual for a classroom
- Create square-format science animations for social media posts
- Build a series of follow-up animations from suggested prompts for a lesson plan
Audience
- Content Creators
- Researchers
- Hobbyists
- Startups
- Business Users
Pros
- No coding or Python installation required

- Generates Manim Community Edition code, the engine behind 3Blue1Brown
- AI voiceovers in 9 languages with 15+ voices
- Exports up to 4K in 16:9, 9:16, and 1:1 formats
Cons
- Requires cloud access; no offline desktop version
- Less direct control than hand-written Manim for advanced custom animations
- Output depends on the clarity of the natural-language prompt
- Proprietary platform; not open source
- May not support every Manim feature or extension
