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.

Hey Community! I built S.U.N.D.A.Y because every voice assistant today sends your data to the cloud. I wanted one that works entirely offline on my Mac. And yes — it was literally built on a Sunday.

What's under the hood:

MLX-Whisper for speech recognition
Kokoro ONNX for natural-sounding text-to-speech
Qwen via Ollama as the brain
Local vision model for webcam and screenshots
Native macOS integration (Calendar, Notes, Mail) via AppleScript
"Hey Sunday" wake word for hands-free use
Stack: Tauri + Python + TypeScript

Requirements: Apple Silicon (M1+), 16GB RAM, macOS 13+

It's v0.1.0 alpha — the core voice loop works well but there's plenty to improve. I'd love feedback on what skills to add next.

Free to download. No account required. Your data stays yours.
