Your AI. Your Data. Your Rules.
The first AI personal assistant that runs entirely on your device. No cloud processing. No data harvesting. Just pure intelligence, completely under your control.
Your Thoughts Are Being Harvested
Every note you take, every thought you capture - popular AI assistants send it all to the cloud where it's stored, analyzed, and used to train models you have no control over.

Intelligence That Stays With You
Three powerful systems that work together - entirely on your device - to capture, organize, and act on your ideas.
FlowNotes
Capture thoughts naturally with AI-powered voice and text notes. Stream-of-consciousness input that your on-device AI structures and enriches automatically.
Knowledge Graph
Your ideas automatically connect and organize into a personal knowledge graph. Discover hidden relationships between your thoughts that you never noticed.
AI Workbench
Generate insights, summaries, and action items from your private data. A powerful AI that works for you without ever leaving your device.
Zero-Trust by Design
Privacy isn't a feature - it's the foundation. Every component is built with the assumption that no one should access your data, not even us.
On-Device AI
AI models run locally using Apple Neural Engine and GPU. Your data never touches a server.
Zero-Knowledge Encryption
End-to-end encryption with keys only you hold. Even we cannot read your data - by design.
Biometric Auth
Face ID, Touch ID, or fingerprint - your biometrics are the only key to your vault.
