Markdown Authoring Best Practices
GitHub Flavored Tables
Use colons in the separator line (| :--- | :---: | ---: |) to align table columns to the left, center, or right.
Interactive Task Lists
Write - [x] for completed tasks and - [ ] for open action items to create elegant todo lists.
Fenced Code Blocks
Specify the language identifier immediately after triple backticks (e.g. ```typescript) for clean syntax styling.
100% Client-Side Privacy
Your manuscripts, documentation, and notes are processed entirely in browser memory. Zero files are sent across the network.
