Kuku

Kuku is a native, local-first AI Markdown workspace for macOS that transforms your notes into a connected knowledge system. Built with Tauri instead of Electron, it combines the speed of native performance with AI-powered search, editing, and linking—all while keeping your data offline and under your control.

Product Highlights

  • Native macOS Performance: Built with Tauri for lightning-fast speed, not the sluggishness of Electron apps.
  • AI-Powered Vault Intelligence: Search, edit, and link your notes with reviewable, Cursor-style diffs that you control.
  • Wikilinks & Graph View: Navigate your thoughts visually with bidirectional linking and interactive graph exploration on plain Markdown files.
  • True Offline-First: No cloud required, no vendor lock-in—your notes stay local and yours forever.
  • Instant Context Retrieval: Get answers from your entire knowledge base in under a second without losing your train of thought.

Use Cases

  • Research & Writing: Upload documents for instant AI learning and retrieval, then edit with contextual awareness across your vault.
  • Project Planning: Use wikilinks and backlinks to connect meeting notes, requirements, and deliverables in a living document system.
  • Secure Note-Taking: Maintain sensitive information completely offline with zero data transmission without explicit permission.

Target Audience

Kuku is designed for macOS power users, researchers, writers, and privacy-conscious professionals who want Obsidian-like linking with modern AI assistance—without sacrificing speed, security, or open-source transparency.
