Markdown-native collaborative docs
Your docs. Your Drive. Every collaborator — human or AI.
Mica is a collaborative markdown docs app that lives 100% in your Google Drive. Plain .md files, Google-Docs-grade collaboration, zero lock-in.
Markdown-native
An Obsidian-style vault for your team
Your vault is just a Drive folder of plain markdown files — browse it as a tree, link notes together, and follow backlinks. No proprietary format, no export step, no lock-in. Your files stay yours.
- Plain .md files stored in your Google Drive
- Vault tree navigation with folders
- Wiki-links and backlinks between notes
Powered by Drive
Google-Docs-grade sharing and history
Sharing, permissions and revision history are Google Drive's own — the ones your organization already trusts and audits. Share by email as viewer, commenter or editor; restore any revision; star the ones that matter as named checkpoints.
- Drive permissions: viewer, commenter, editor
- Full revision history with one-click restore
- Named checkpoints kept forever
Realtime
Live multiplayer editing
Write together like it's a Google Doc: live cursors, presence, and conflict-free merging over CRDTs — while the file underneath stays clean, diffable markdown.
- Live cursors and presence for every collaborator
- Conflict-free offline edits that merge cleanly
- Falls back gracefully when the relay is unreachable
AI-ready
Connect Claude and other AI via MCP
Every collaborator gets a seat — including the artificial ones. Mica speaks the Model Context Protocol, so Claude and other assistants can read, draft and edit docs in your vault with the same permissions model as humans.
- MCP server for AI read/write access to vaults
- Same Drive permissions apply to AI collaborators
- Markdown in, markdown out — no lossy conversion
