Kuku is an innovative note-taking and knowledge management application designed for macOS, seamlessly integrating a simple Markdown editor with cutting-edge AI features while ensuring your files remain in plain .md format on your device, thus allowing compatibility with editors like vim, enabling version control through git, and avoiding dependency on cloud providers. The app facilitates bidirectional linking, complete with autocompletion and a backlinks panel to enhance the connection between your thoughts, alongside a graphical representation to visualize the interrelations among your notes. Furthermore, it boasts an AI assistant powered by Gemini that can search within your local vault, read documents, summarize content, and provide options to create or modify files, showcasing suggested edits in a cursor-style preview that allows for easy acceptance or rejection of changes. Kuku enhances productivity with local Whisper speech-to-text functionality for offline audio transcription, employs a rapid full-text search system using SQLite FTS5 with BM25 ranking, and features a native performance profile developed on Tauri, resulting in a compact installation and minimal memory consumption, free from the bloat often associated with Electron applications. Additionally, Kuku’s user-friendly interface ensures that both novice and experienced users can navigate its features effortlessly, making it a versatile tool for personal and professional use.
