kuku

Kuku is a local-first markdown workspace for macOS built on Tauri (not Electron), with Rust, Go, and TypeScript components and an MIT license. Its differentiator is AI-native editing: Agent, Ask, and Inline modes can read and edit your vault, but every proposed change goes through a Cursor-style reviewable diff that you accept or reject — so AI assistance never silently rewrites your notes.

Not yet. The current build is macOS-only, and the kuku.mom homepage explicitly lists Windows and Linux as Coming soon. Because the macOS client is paired with a Go-based sync server and Docker infrastructure in the same repo, the long-term plan is to ship native clients on the other desktop platforms rather than rely on a web wrapper.

Your notes are plain .md files in a local vault that works with git, vim, and Obsidian-compatible tools. The repo describes an encrypted sync foundation using key envelopes, signed commits, and encrypted objects, so the server never sees plaintext notes. You can run kuku entirely offline, sign in for managed convenience, or self-host the Go server stack yourself.

Kuku is released under the MIT license, so the desktop app and the self-hostable server stack are free and open source. The website hints at a managed cloud option (sign in for managed convenience) for users who do not want to run the Go sync server themselves, but the core product is source-available on github.com/kuku-mom/kuku.
