Kuku

As a macOS Markdown editor, Kuku differs from most note apps by keeping everything on your own disk.

Kuku is a local-first note-taking and knowledge management tool that stores notes as plain .md files, with wikilinks, backlinks and a graph view, so there is no cloud lock-in.

It is built with Tauri, which the makers pick over Electron for lower resource use.

The AI side is an agent powered by Gemini with tool calling.

It can search your vault, read files and create documents.

Any change it makes to your notes appears as a Cursor-style diff, so you review and accept edits before they land.

That is a sensible guard if you do not want an assistant rewriting your files unseen.

Kuku also does speech-to-text offline using Whisper, so dictation runs on your machine.

Full-text search covers the whole vault.

It is a Mac-only app.
