Kuku: open source - Your open-source, local second brain for every AI
by•
Kuku is back as an open-source, local-first second brain for the AI era. It keeps your knowledge in plain Markdown files, then turns your vault into reusable context: wikilinks, backlinks, graph, search, and AI-assisted edits with reviewable diffs. Unlike closed note apps or one-off AI chats, Kuku is built to make your memory portable across tools, models, and self-hosted setups.

The Tauri-not-Electron call is the part I appreciate most. The Obsidian comparison gets a lot of attention but the bigger story for me is the binary size and idle memory profile when you actually run a markdown editor on a laptop alongside a dozen other apps. Going to try this on my secondary work machine first.

That’s exactly one of the things we cared about.
A Markdown editor is something you keep open all day, so we think it should feel lightweight and natural on the OS, not just feature-rich. In real work environments where you’re running a dozen other apps, binary size and idle memory usage matter a lot.
Would really appreciate any feedback after you try it on your secondary work machine, especially around performance and UX.
Idk but something about the diff view gives me confident with the interaction around these tools, it feels good to see the changes that are actively going through and with the agent memory setup like that hard battle tested obsidian architecture , is there a way to import all your previous obsidian setup to onboard instantly and since it is a tauri app are you planning to add support for other os
@bigmacfive How will you handle contribution workflows for the AI agent's diff-review system, will you use a specialized PR template or automated checks to ensure edits stay reversible and transparent?
