Social Media Text Formatter and Preview

Style your posts with Unicode formatting, then preview how they'll look — before you publish.

What it does

A free, lightweight browser extension side panel for formatting and previewing posts before you publish them. Platform-neutral — it works for LinkedIn, X (Twitter), Facebook, Instagram, and Threads.

Inline editor — style a selection or the whole post.
14 text styles — Bold, Italic, Script, Fraktur, Double-struck, Monospace, and more, using real Unicode glyphs so they paste anywhere.
List tools — bullet, numbered, checklist, and dash lists.
Emoji picker and one-click copy.
Live preview with per-platform character limits and "see more" truncation.
Follows your OS/browser light or dark theme.

Privacy & permissions

No network requests, no data collection, no tracking. The extension requests a single permission (sidePanel) and never reads your clipboard. Read the full Privacy Policy.
