A local markdown vault curated by AI.
Every note is a regular .md file in a folder you choose. No database, no proprietary format, no lock-in.
Full-text across body and frontmatter, plus on-device semantic search via Apple's NLContextualEmbedding.
One Swift codebase, three first-class experiences: SwiftUI on iPhone and iPad, AppKit on Mac.
Switch between live preview and source. Tables, KaTeX, Mermaid, and code all render inline.
Bring your own Anthropic or OpenAI key, talk via Shortcuts, or run a local Ollama model.
Link freely between notes. Build Dataview-style lists, kanban boards, and inline query blocks.
Expose your vault as tools to Claude Desktop, Cursor, or any MCP client — and use external MCP tools inside the app.
Share extension, Safari clipper, Watch app, widgets, a macOS menu-bar applet, and Shortcuts.
No telemetry, no account, no network calls unless you opt in.
