# Intabula

> Intabula is a local-first Markdown notes app for Mac with a built-in, sandboxed AI agent. Folders become collections with typed fields, table and Kanban views, and full-text search; the agent edits the same files through sixteen typed operations instead of a shell. It runs on the user's existing Claude or Codex subscription (no API keys), works on existing Obsidian vaults as-is, has an iOS companion app, and syncs through the filesystem (iCloud Drive, Dropbox, Git) with no server or account.

Key facts: every note is a plain Markdown file with YAML frontmatter; the SQLite index is a rebuildable cache; the agent has no shell and no direct file access; field edits are byte-exact splices; renames rewrite every wikilink atomically under a crash-recovery journal; every agent write is logged with a before/after diff; schema is inferred from recurring fields, and violations flag to an inbox instead of being rejected.
