Post Formatter

Post Formatter is a browser extension that gives your LinkedIn posts — and other social updates — more typographic options than plain text usually allows. It adds bold, italics, underline, strikethrough, lists and over 20 Unicode font styles so you can make sections of a post stand out while you write in the native editor.

There’s an AI proofreading and rewrite feature that checks grammar, spelling and tone inside the editor, and it keeps your Unicode styling intact. You can provide your own API key and choose the model you prefer.

It also includes a live preview of how posts will look (including dark mode and common media types), plus a drafts manager so you can save, tag and organise posts before publishing. More details at https://postformatter.com/.

• Floating toolbar in the editor for quick formatting
• AI proofread and rewrite (user-supplied API key)
• Live post previews across platforms, including dark mode
• Drafts manager with folders, tags and quick insert
• Smart paste from Google Docs, Word or Notion that preserves bold/italics
• 20+ Unicode fonts, symbols, emoji and keyboard shortcuts
