Postlette

A tiny desktop editor that adds Unicode emphasis for social posts.

Postlette uses Unicode characters, not rich text formatting. Platforms may render these characters differently.

What it does

  • Apply Unicode bold, italic, and bold-italic to selected text.
  • Insert em dashes and separators at the cursor.
  • Insert emoji from a local picker.
  • Copy the result to your clipboard.
  • Open and save plain text files (.txt).

Quick start

  1. Run the app.
  2. Type or paste your post into the editor.
  3. Select text and apply styling from the toolbar.
  4. Use 📂 to open a .txt file or 💾 to save your work.
  5. Click Copy to copy the result.

Principles

  • Offline only. No network calls.
  • Compatibility-first. We only transform A–Z/a–z/0–9 as documented.
  • Reversible styling with Unstyle.

Note: Use styling sparingly for readability. Heavy Unicode styling can be harder for screen readers and copy/paste.
