Kuku

Kuku is an AI-native Markdown editor designed for macOS that combines the power of local file storage with intelligent AI assistance. Built on Tauri v2 with a Rust backend, it delivers native performance in a lightweight ~15MB bundle while using only ~80MB of memory. The app lets you write in plain Markdown files that stay on your disk, compatible with tools like Obsidian, vim, and git.

• Plain Markdown Storage keeps your files as .md on your local disk with no vendor lock-in, allowing you to open them with any editor or version control system.

• Bidirectional Links enable wiki-style linking with [[double brackets]], autocomplete suggestions, and a backlinks panel to see all connections to the current document.

• Graph View provides a force-directed visualization of document connections, letting you click to navigate and drag to explore your knowledge network.

• AI Agent with Tool Calling uses Gemini to search your vault, read files, and create documents automatically—functioning like Cursor but for your notes rather than code.

• Cursor-style Edit Preview shows AI-suggested edits as diffs before applying them, giving you control to accept or reject each change individually.

• Local Whisper STT enables offline speech-to-text using whisper.cpp with no API calls required, so voice input works without internet.

• Full-text Search leverages SQLite FTS5 with BM25 ranking and supports Korean tokenization for fast, accurate document discovery.

• Native macOS Performance through Tauri means Safari-level performance without Electron bloat—1/10 the bundle size and 1/3 the memory usage.

To get started, download the app from GitHub releases or install via Homebrew with brew install --cask kuku-mom/kuku/kuku. Open any folder containing Markdown files, including existing Obsidian vaults, and start writing. The AI features require a Gemini API connection, but all other functionality works completely offline.
