Built on your Google Drive
AI-native editor & file manager.
Zero content stored.
You, your team and your AI write together, live, and Mica keeps your files organized. It works with the AI you already use (Claude, ChatGPT, Codex) and never calls a model itself, so there's no second AI bill. Live today for Google Drive.
Organized
Your Drive, kept in order
Drives fill up faster than anyone files them: AI-written docs, PDFs, spreadsheets, copies of copies. Mica maps each folder you connect and checks every file in it, so the right one is easy to find and the old one stops getting quoted.
- A map for each folder you choose: its purpose, naming conventions and where to start, every file in it, and a one-line summary of each doc
- A check across every file, whatever its type, that finds duplicates, old-version chains, empty and scratch files, broken links, names that break the folder's pattern and unfiled items, with a health score from 0 to 100
- Draft, current, superseded and archived statuses for your docs, so search puts the current version first
You stay in charge
Propose, review, undo
A cleanup arrives as a proposal: moves, renames, statuses, merges and trash, each with a reason. You review it in Mica before anything changes, accept what you agree with and reject the rest. Ask your AI to go ahead without a proposal and every change is still recorded, and can be undone.
- Accept all, accept some or reject them, item by item
- Undo changes later; trashed and merged docs can be brought back for 30 days
- In a team folder, a proposal that touches someone else's doc goes to its owner to accept
Your AI
Works with the AI you already use
Connect Claude, ChatGPT or Codex to Mica once. Ask it to map a folder, propose a cleanup or give a folder a full check-up, and it does the work through Mica, as you. Mica does the checking. Your AI does the thinking. You approve the changes.
- Mica never calls an AI model to organize your folders, so there is no second AI bill
- In the editor, press ⇧⌘K to ask Claude, ChatGPT, Gemini or Grok about the open doc with your own API key, which stays in your browser
- AI connections act under your own Drive permissions, and you can revoke them any time
Editor
Write together, live
See the page as you type, see everyone else's cursor, and see your AI's too. Your AI can suggest changes as tracked edits and join the comment threads, the same way a colleague would.
- Headings, callouts, math, tables and task lists render in place; docs open in Reading mode until you switch to Edit
- Suggestions and comments for people and AI alike; your AI can make up to 20 edits in one all-or-nothing change
- @-mention a teammate, and if the live connection drops, Mica keeps autosaving and merges your edits when it returns
Yours
A folder you already own
Every Mica doc is an ordinary file in your own Google Drive, sitting right beside your Google Docs, Sheets and PDFs. Nothing is converted or trapped, and sharing uses Drive's own permissions.
- Mica docs are saved in markdown, a plain-text format any app can open, so they stay yours with or without Mica; PDFs open for reading, Word and Excel files preview, and Google Docs and Sheets open in Google
- Share as viewer, commenter or editor and Mica writes a real Drive permission, so access follows the file
- Readable version history stored in your Drive beside each doc, with a diff and one-click restore
And the rest of what you would expect
Linear built in
Paste a Linear link and it becomes a live chip. Change status, owner or due date and reply to comments without leaving the doc.
Looks the way you want
Light, dark or system, your own accent and fonts, five themes, and an app you can install on your desktop or phone.
Find and link anything
Search every connected folder by name and full text with ⇧⌘F, and type [[ to link another doc. The link survives renames and moves.
Privacy
Your files stay yours
Mica is built so there is nothing of yours to lose. Delete Mica and every document is still sitting in your Drive.
- Document content lives only in your Drive, your browser, and the live-editing relay's memory during a session
- Mica stores file ids and byte counts, never your content or a readable copy of titles or file names
- Encrypted in transit and at rest, and the OAuth tokens Mica holds are encrypted too
- No ads, no training on your data, and no human reads it
- Cookieless analytics that carry no identifiers
- AI keys you add to the Assistant stay in your browser and never reach Mica's servers
Trust
Built to earn your trust
Mica asks for Drive access so it can open the files you choose. It is independently assessed, verified by Google, and keeps no copy of what you write.
Your docs stay in your Drive
Every document is a .md file in your own Google Drive. Mica's servers keep no copy of the text, and no readable copy of the title or the file name.
CASA Tier 2 validated
