What's inside
Local First
Your vault lives on your machine as plain Markdown files. No account, no server, no subscription required to write.
Wikilinks & Backlinks
Link notes with [[note name]] syntax. Every link is tracked bidirectionally, so each note knows what references it.
Full-Text Search
Find anything across your entire vault instantly. Search by filename, content, tags, or wikilink references.
Split Panes
Work on two notes side by side, or open a live Markdown preview alongside your editor.
Tabs
Keep multiple notes open at once. Each tab maintains its own cursor position and scroll state.
Knowledge Graph
Visualize the connections between your notes. See clusters form as your thinking develops.
A grimoire is a book of collected knowledge — spells, observations, secrets accumulated over time. Your notes deserve to be treated the same way.

Common questions
- What is Grimoire?
Grimoire is a local-first Markdown editor for macOS, built for writers, researchers, and knowledge workers. It stores your notes as plain Markdown files on your own machine and adds wikilinks, backlinks, full-text search, split panes, tabs, and a knowledge graph on top.
- Is Grimoire free?
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.
- Where are my notes stored?
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.
- What file format does Grimoire use?
Standard Markdown (
.md) files in ordinary folders. There is no proprietary database and no lock-in — you can open, edit, back up, or migrate your notes with any other tool at any time.- Does Grimoire work with Claude or other AI assistants?
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.
- What platforms does Grimoire run on?
Grimoire runs on macOS 13 or later, with native builds for both Apple Silicon and Intel Macs. It is currently in public beta.
