On-device AI posture detection via webcam without cloud processing or subscriptions.
Webcam head-tracking for window focus without buying expensive eye-tracking hardware.
Scroll-to-Focus uses a CGEventTap + AXUIElement to raise the exact window under the cursor, while Eye Tracking feeds webcam frames to Vision and blends head yaw + pupil offset for per-monitor focus — a tidy mix of low-level macOS APIs and ML-ish heuristics. Real-world details are handled too (calibration flow, sound/notification feedback), but expect friction from macOS permissions and the webcam requirement.
Multi-tool session monitor via PTY wrapping, plugin events, and fallback scanning.
The project nails a practical niche: zero-latency P2P audio via WebRTC with PeerJS signaling so your stream never routes through a cloud service. The clever (if hacky) hidden 1x1 base64 looping video to keep Mobile Safari's microphone alive shows someone dug into platform quirks — useful and real-world, but also a reminder this is an MVP with battery and backgrounding tradeoffs.
Native SwiftUI app with a tidy card-based UI and an anonymous, device-tied model — no account required — which is a smart privacy-first choice for a monitoring utility. The backend on Cloudflare Workers keeps the footprint minimal and the one‑time Pro unlock for unlimited domains + webhooks/API is pragmatic, but lack of a web dashboard or multi-device sync limits it to solo operators for now.
