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

Bring your Drive. Keep your markdown.

Free to try — connect a vault in under a minute.
