Refract

Refract is a native intelligence system designed for high-stakes meetings and interviews. It listens, remembers, and answers in real time entirely on the user's machine, using a model of their choice. The system is built for privacy, with no servers holding transcripts and no vendor holding keys. It requires macOS 12+ (Apple Silicon & Intel) or Windows 10/11. Refract offers real-time transcription, memory, and answers that never leave the machine. It supports bringing your own model and is source-available and auditable. The tool is free to start, with competitors charging $20–$149/month. It has over 9,000 users and 700+ daily active users, with latency under 500ms and zero data breaches. Refract is a complete, native intelligence system, not just an API wrapper. It features native audio capture with Rust and Zero-Copy ABI transfers, local Whisper STT using optimized ONNX models, dual-channel intelligence for system audio and microphone, and a battle-tested stealth mode. It includes a modes manager with 7 personas, custom context and notes, rolling context, local RAG memory, reference files, a rich dashboard, and fully offline capability. The system is designed to be private by architecture, not by promise, and users can audit every line of the source code.
