kuku

kuku is an AI-native Markdown editor designed for people who want to connect their thoughts without vendor lock-in. It stores all your files as plain .md files on your local disk, making them accessible with any text editor and compatible with tools like Obsidian. The editor supports standard Markdown features alongside advanced knowledge management capabilities.

The tool uses Gemini for AI assistance but distinguishes itself with tool-calling capabilities that allow the AI to search your vault, read files, and create new documents. It shows AI edits as diffs before applying them, similar to Cursor's approach. For offline functionality, kuku integrates local Whisper speech-to-text using whisper.cpp, eliminating the need for API calls. The interface includes bidirectional linking with autocomplete, a graph view for visualizing connections, and SQLite-based full-text search with Korean tokenization support.

kuku works best for knowledge workers, researchers, and writers who need to organize complex information while maintaining control over their data. It's particularly useful for creating connected note systems, writing with AI assistance while keeping final editorial control, and working with sensitive information that requires offline processing. The native macOS app built with Tauri ensures lightweight performance without Electron bloat.
