Post Formatter
Post Formatter is a Chrome extension and companion website designed to format text for LinkedIn posts and other social platforms. It lets users apply bold, italic, and a library of 30+ Unicode-based font styles to plain text so that formatting survives copy-and-paste into platforms that do not natively support rich text editing. The extension injects a formatting toolbar directly into the LinkedIn composer, and it also states support for X (Twitter), Facebook, Threads, and similar networks. Beyond styling, the product bundles writing assistance features into the same interface. It advertises an AI proofreading capability that reviews drafts for spelling, grammar, and readability, plus a drafts system for saving and reusing post variations. A live preview shows how the formatted text will render before the user publishes, which addresses the common problem of Unicode characters displaying inconsistently across devices and applications. The service is offered free of charge and is distributed primarily through the Chrome Web Store, with the marketing site providing a standalone web-based text formatter, style examples, a blog, and an FAQ. The website is localized into more than a dozen languages including German, Dutch, French, Italian, Spanish, Polish, and Portuguese, indicating an international user base of social media writers and personal-brand marketers. Because formatting is achieved with Unicode character substitution rather than platform-native rich text, the resulting posts generally remain plain text and therefore render differently depending on the reader's operating system, font stack, and any screen-reader software in use. The tool is positioned as a lightweight productivity aid rather than a full social media management suite.

Problem solved
LinkedIn and most social platforms do not provide native bold, italic, or decorative text formatting in posts, so creators cannot emphasize headlines, hooks, or key phrases. Post Formatter solves this by converting typed text into Unicode character variants that survive copy-and-paste, and by adding AI proofreading, saved drafts, and a live preview inside the browser so writers can style and check a post without leaving the composer.
Use cases
