Obsidian — but a lot has changed
Kuku is a native, local-first markdown editor designed for macOS users who prioritize privacy, speed, and flexibility. Built with Tauri instead of Electron, it offers a lightweight, offline-capable experience where notes are stored as plain markdown files, supporting wikilinks, backlinks, and visual graph views. Its standout feature is an integrated AI agent that not only chats but actively searches, edits, and links files, presenting changes with Cursor-style diffs for transparent review. This combination of traditional note-taking with AI-driven enhancements makes Kuku ideal for writers, researchers, and productivity enthusiasts seeking a seamless, privacy-focused environment. Its offline-first design ensures data security and quick access, while its modern UI and robust features offer an Obsidian-like experience minus the bloat and cloud dependencies.
