Grimoire is a local-first desktop app for Game Masters to manage lore, NPCs,
maps, and session prep — a focused creative instrument for the world you're
building.
Prerelease (0.X.Y). Local-first and stable at the core; iterating fast.
Features
- 📁 Local-first ledgers — your campaign is a portable local folder; move it anywhere without breaking links.
- ✍️ Markdown notes — distraction-free editor; notes are plain
.md files, never locked in.
- 🔊 Ambient audio scenes — layer local audio and Spotify tracks into custom soundscapes.
- 🗺️ Interactive maps — annotate world maps with pins and categories.
- 🎨 Arcane clarity — a warm, parchment-and-ink interface tuned for clarity under pressure.

Releases page:

Builds are currently unsigned — your OS may warn about an unidentified
developer on first launch (macOS: right-click → Open; Windows: More info → Run
anyway).
On first launch you'll pick a folder to use as your Ledger; Grimoire stores
its campaign database in a hidden .grimoire folder inside it.
