Slouch - AI Posture Coach
I kept catching myself slouching during long coding sessions and realized most posture apps either need expensive hardware or send your webcam feed to some server — neither felt right. So I built Slouch: a posture coach that runs 100% in the browser using MediaPipe Pose.
Key Highlights
- No backend, no data leaving your device, ever
- The app analyzes your posture in real-time through torso metrics like shoulder width, hip alignment, and tilt
- I added a smart calibration system so it adapts to your body and chair setup, time-delayed alerts to avoid false triggers from quick movements, and sensitivity presets (Easy/Medium/Hard) so you can ease into it
- When you slouch too long, you get a gentle audio nudge
- Built with React, TypeScript, and a glassmorphism UI
- Currently live at slouch.pro with a waitlist powered by Supabase
