Connect your favorite agent to your Obsidian vault.
Works with the vault you already sync with Obsidian Sync. Ask Claude or ChatGPT to file a note, update a project or find what you wrote last spring, and the change turns up on every device you own.
Nothing to install, run or host. Sign in, connect your vault and paste one URL into your AI client.
Needs Obsidian Sync, Obsidian’s paid sync service.
Ask in the chat. It’s in the note.
Your AI client, and the same note in Obsidian a few seconds later.

- It pauses, and it’s deleted 14 days later unless you subscribe again. Your notes stay in Obsidian Sync.
The terms have the details.
The careful parts.
What we hold, where it lives, and how to make it disappear.
- Your encryption password stays in the browser.
- If your vault has an end-to-end encryption password, your browser turns it into the vault key. The password itself never reaches us.
- Your Obsidian password is never kept.
- We trade your Obsidian email and password for a sign-in token, then keep the token and vault key encrypted and locked away. Never in our database, never in our logs.
- Your space is yours alone.
- Every account gets its own isolated MCP server. No other user can get into it.
- Deleting takes everything we hold.
- Deleting your space removes it, its snapshots and the stored credentials. Your notes stay in Obsidian Sync, and the Obsidian access token stays valid until you revoke it in your Obsidian account.
The privacy policy has the details.
Before you start.md
Before you start
- A vault on Obsidian Sync, Obsidian’s paid sync service. We recommend a new vault just for AI, so your main vault stays out of reach.
- Claude, ChatGPT, Claude Code or another remote MCP client
- A browser. No terminal, no computer left on.
Your notes, one question away.
