About Trello Markdown Editor

Trello Markdown Editor Tired of Trello's rich text editor auto-converting your markdown as you type? This extension brings back the simple, distraction-free editing experience you've been missing. The Problem Trello's newer editor uses a WYSIWYG (What You See Is What You Get) approach that automatically converts markdown syntax into formatted text as you type. While this might be helpful for some users, it can be frustrating if you: • Already know markdown and don't need visual helpers • Want to see and edit the raw markdown directly • Find the auto-conversion behavior disruptive to your workflow • Prefer a clean, predictable text editing experience • Need to copy/paste markdown between applications The Solution Trello Markdown Editor replaces the rich text editor with a plain textarea whenever you edit a card description. You get a simple, monospace text area where you can write markdown without any interference or auto-formatting. Features • Plain Text Editing — Write markdown exactly as you intend, without auto-conversion or formatting surprises • Monospace Font — Easy-to-read fixed-width font for better alignment and code readability • Dark Mode Support — Seamlessly matches Trello's dark theme • Non-Destructive — Click "Cancel" at any time to restore the original Trello editor • Direct API Integration — Saves your changes directly via Trello's API, just like the native editor • Lightweight — No background processes, no data collection, minimal permissions How to Use 1. Open any Trello card 2. Click "Edit" on the description 3. The rich text editor is automatically replaced with a plain textarea 4. Write your markdown directly 5. Click "Save" to save your changes, or "Cancel" to restore the original editor Privacy This extension: • Does NOT collect any personal data • Does NOT transmit any data to third parties • Only activates on trello.com • Only accesses the Trello API to read and save card descriptions (the same API Trello's own editor uses) Open Source This extension is open source and available on GitHub: https://github.com/slhck/trello-markdown-editor Permissions Explained • Host permission for trello.com: Required to inject the markdown editor and communicate with Trello's API
