Post Formatter
Post Formatter is a Chrome extension for formatting and previewing LinkedIn and other social posts with free text styles, drafts, Smart Paste, and AI proofreading.
Overview
Post Formatter is a Chrome extension for writing and formatting social posts directly inside supported editors. It adds inline text styling, Unicode font variants, previews, drafts, and helper tools for turning pasted content into social-platform-friendly text.
The core formatting tools are free forever, while Post Formatter Pro adds AI proofreading, premium styles, live LinkedIn preview, multi-platform post previews, Smart Paste, and expanded draft features. The product is built for people who write frequently on LinkedIn and other supported social networks and want formatting controls without leaving the post composer.
Features
Unicode style library
Use 20+ Unicode text styles such as monospace, script, fraktur, double-struck, bubble, square, small caps, wide text, reverse, upside down, and zalgo. These styles are meant to copy across social platforms without special rendering.
Lists and symbols
Create bullet, numbered, lettered, and emoji lists, plus use a symbols and emoji library with search and recently used items.
Live previews
Preview posts before publishing on LinkedIn, X, Threads, Facebook, and Bluesky, including a LinkedIn live preview that updates as you type. Dark mode is included.
Draft management
Save drafts, organize them with folders and tags, mark them ready to publish, and reopen them for editing. The extension also supports right-click draft insertion and a side-panel editor.
Smart Paste and AI tools
Paste from Google Docs, Word, Notion, or Markdown and keep formatting by converting it into Unicode equivalents. The extension also includes AI proofreading and auto-styling, with the option to use your own OpenRouter key.
Use cases
LinkedIn post formatting
Format LinkedIn posts directly in the composer when you want bold, italic, underline, or Unicode font styles without switching to another app.
Cross-platform social publishing
Prepare posts for X, Facebook, Threads, Bluesky, YouTube, or Pinterest and use previews to check how the text will render before publishing.
Draft organization
Keep recurring post ideas, drafts, and reusable copy organized with folders, tags, and a ready-to-publish status.
Importing formatted text
Paste content from Google Docs, Word, Notion, or Markdown and preserve emphasis and list structure in a social post.
Editing and cleanup
Use AI proofreading to catch typos and style issues, or have AI emphasize key phrases with bold and italic in plain text.
