Metis Documentation
Everything you need to turn a folder of Markdown into a connected, AI-native knowledge base. New here? Start with the getting-started guide.
Writing
Live-preview Markdown editor, reading mode, GFM tables, code highlighting, and LaTeX math.
Vaults & organization
A vault is a folder of notes. Use the folder tree, breadcrumbs, and multi-vault switching to mirror how you think.
Properties
Typed YAML front matter (status, owner, due, custom keys) edited as color-coded chips - round-trips with Obsidian.
Links & graph
[[wiki links]], automatic backlinks, aliases, unlinked mentions, and a graph view of the whole vault.
Search
Keyword search with operators (tag:, path:, title:) and on-device semantic search by meaning.
On-device AI
Summarize, suggest tags/links, writing assist, Ask Vault, and review digests - all private, on macOS 26.
Tasks & agenda
Markdown checklist tasks and due-date properties roll up into one agenda; toggling writes back to the note.
Version history
Make a vault a git repo for snapshots, per-note history, diffs, restore, and optional auto-snapshot.
Sync & interop
Optional iCloud file sync, import/export of files and folders, and a Plain Markdown mode that edits a project folder in place.
