Description
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.
