Synchronized source and preview
A code editor and rendered Markdown preview appear side by side. Editing either surface updates the other for all collaborators, with cursors included.
Markdoc
Markdoc is a collaborative Markdown editor with synchronized source and rendered preview, real-time co-editing, comments, suggestions and version history. It connects to GitHub gists and repositories for opening files and publishing commits, and requires a GitHub account.
Collaborative Markdown editing
Markdoc is a collaborative Markdown editor for teams or individuals who need to write, review and maintain Markdown documents together. It combines a code-oriented source editor with a rendered preview, keeping both views synchronized as people edit.
The product supports live collaboration, anchored review threads, tracked suggestions and version history. Markdown files can be opened from GitHub gists or repositories, then published as commits to a chosen branch. The homepage describes offline editing with synchronization after reconnection.
Key features
Real-time collaboration
Presence indicators, live carets and selections support simultaneous editing, while conflict-free merging handles concurrent changes.
Contextual comments
Threads can be anchored to text and continue to follow the relevant words as the document changes. Participants can reply, resolve and reopen threads.
Tracked suggestions
Suggesting mode records proposed edits as tracked changes. Document owners can accept or reject suggestions individually or all at once.
Version history
Automatic snapshots, named versions, word-level diffs and one-click restore provide a record of document changes.
GitHub-native storage and publishing
Markdown files can be opened from GitHub gists or repositories, and publishing creates a commit on a selected branch.
Use cases
Writing Markdown documentation
Draft and refine README files, documentation pages or other Markdown files while viewing source syntax and the rendered result together.
Co-authoring documents
Work on the same document with collaborators who need to see presence, cursors and selections while changes are merged in real time.
Structured editorial review
Review proposed wording or structural changes without directly replacing the current text; owners can accept or reject tracked suggestions.
Contextual feedback
Discuss specific passages with threads that remain attached to the relevant words, even as the document evolves.
Maintaining document history
Recover or compare earlier states using snapshots, named versions, word-level diffs and one-click restore before publishing an update.
