SUNDAY is a voice-first AI assistant that runs 100% locally on Apple Silicon. No cloud. No subscriptions. No data leaving your machine. Hold Space, talk, get a spoken answer. It reads your Calendar, Notes, and Mail. It sees your screen and webcam. It searches the web, manages files, and controls your Mac — all by voice, all on-device. Powered by Whisper, Kokoro TTS, and Qwen via Ollama. JARVIS-inspired interface. Models download automatically on first launch. Free and open alpha.
