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.

Kuku is a truly native, local-first markdown editor for macOS — built with Tauri, not Electron. Notes are stored as plain .md files with wikilinks, backlinks, and graph view. Its AI agent doesn’t just chat — it searches, edits, and links your files, with every change shown as Cursor-style diffs you can review. Fast, lightweight, offline-first. No cloud. No lock-in. Obsidian + Cursor, without Electron.
