StraightUp — posture coach

A privacy-first posture coach. Runs 100% on-device — your camera never leaves your machine. Sit upright, effortlessly.

StraightUp watches your posture through your webcam and nudges you the moment you start slouching — so you build better habits without thinking about it. HOW IT WORKS ────────────── 1. Click "Open coach" — a small floating window appears alongside your work 2. Hit Calibrate once while sitting upright 3. Go back to whatever you were doing StraightUp runs silently in the background. If your posture drops, it rings a bell. Fix your posture — the bell stops. That's it. ALERT SYSTEM (graduated, not spammy) ────────────────────────────────────── • Bell rings after 8 seconds of slouching • Screen-edge red glow appears as a visual cue • OS notification after 45 seconds of sustained slump • Repeats every 3 minutes if you're still slouching • Everything stops the moment your posture recovers BONUS WELLNESS REMINDERS ────────────────────────── Built-in timers remind you to drink water (every 30 min), rest your eyes with the 20-20-20 rule (every 20 min), and stand up to stretch (every 45 min). 100% PRIVATE — YOUR CAMERA NEVER LEAVES YOUR DEVICE ────────────────────────────────────────────────────── All AI processing runs locally using Google's MediaPipe on-device model. No video, no images, no biometric data is ever uploaded or stored anywhere. There are no accounts, no servers, and no analytics. WORKS EVEN WHEN YOU SWITCH APPS ────────────────────────────────── Detection keeps running while you work in other applications. The bell will start and stop correctly whether you're in Chrome, VS Code, Word, or anywhere else.
