GitHub-flavored

const hello = (name: string) => `Hi, ${name}`;
NOTE
Try editing this — it's the real editor.
Editing your way
Side-by-side, or one pane at a time.
Write with a live preview beside you and synced scrolling, or switch a single pane between code and rendered view. Your cursor and scroll stay put when you flip.
Yours, and offline
Write offline. Sync when you want.
Your documents stay in your browser unless you enable sync or sharing. Core editing, local search, and export all work with no connection — sign in only for cross-device sync. Install it as an app on Mac, iPhone, Android, and Windows.
Real GitHub-flavored Markdown
Everything you'd expect — and the hard parts too.
Tables, task lists, and syntax-highlighted code, plus Mermaid diagrams, KaTeX math, footnotes, and GitHub alerts. One pipeline renders your preview and every export, so they never disagree.
What it renders
Tables, task lists, and code — exactly like GitHub.
| Feature | Status |
|---|---|
| Tables | ✓ |
| Task lists | ✓ |
| Code + math | ✓ |
- Tables and task lists
- Mermaid diagrams and KaTeX math
- Your next note
TIP
Mermaid diagrams, footnotes, and GitHub alerts all render here.
export const render = (md: string) => pipeline.process(md);
Export anywhere
Take your writing with you.
Export a self-contained HTML file, a print-quality PDF, or a Word document — all generated on your device from the same rendered output.
