Realtime Editor

What it does

A collaborative rich-text editor that keeps one shared document in the chat. Whoever has it open sees the others' cursors and typing in real time; the document also syncs through regular updates, so it works offline and merges changes later. It supports headings, lists, bold, italic and code, with Markdown-style shortcuts.

How to use it

1. Open the app and start typing
2. Use # for a heading and - for a list, or the toolbar
3. Others with the app open see your typing and cursor live
4. Changes are saved to the chat and merged when people come back online
