Markdown, together.
A shared editor for Markdown — source and preview side by side, live for everyone.
Edit the source or the rendered page; both update for everyone at once. Review with comments and suggestions, keep every version, and publish straight to a gist or a repository.
Two surfaces, one document
A code editor and a rich preview side by side. Type in either one; the other follows instantly, cursors included.
Real-time collaboration
Presence, live carets and selections, conflict-free merging on both surfaces. Works offline and catches up when you reconnect.
Comments that stick
Anchor threads to text; they follow the words as the document changes. Reply, resolve, and reopen.
Suggesting mode
Propose edits as tracked changes. Owners accept or reject each one, or all at once.
Version history
Automatic snapshots while you work, named versions when it matters, word-level diffs, one-click restore.
GitHub-native storage
Open any Markdown file from a gist or repository. Publishing creates a real commit on the branch you choose.
