Yes. The editor is free to download and use — unlimited notes and vaults, wikilinks, backlinks, search, the knowledge graph, split panes, and tabs, with no account required. Grimoire Pro ($5/month or $48/year) adds optional cloud sync across devices, version history, and priority support.

On your device, as plain Markdown files in a folder you choose (your vault). Grimoire works fully offline and never sends your notes anywhere unless you explicitly enable the optional Sync service.

Yes. The free Grimoire MCP plugin connects your vault to Claude Desktop via the Model Context Protocol. Claude can search your notes, read and write files, and follow backlinks — while your vault stays on your machine. See the Claude & MCP page for details.

No. Download the app and start writing — no account, sign-up, or internet connection required. An account is only needed if you subscribe to the optional Pro sync service.

Sync is opt-in. If enabled, your vault files are transmitted over HTTPS and stored on Grimoire servers solely to sync them to your other devices — they are never read, analyzed, indexed, or shared. Without Sync, your notes never leave your machine. Full details in the privacy policy.
