- Open the tool — Keep it running in a side tab while you work, study, or code.
- Start the camera — Click "Start Camera" and allow webcam access. Position yourself so your upper body is visible.
- Monitor your posture — The AI analyzes your shoulder alignment, head position, and torso angle in real-time. A green banner means good posture; a red alert means you need to straighten up.
- Set your preferences — Adjust sensitivity (Low/Medium/High) and toggle the alert sound on or off.
- Use the Focus Timer — Start the built-in Pomodoro timer (25 min work, 5 min break) to combine posture monitoring with productivity tracking.
AI Posture Coach — Real-Time Posture Monitor
This tool uses AI-powered computer vision to monitor your sitting posture in real-time through your webcam. It runs entirely in your browser — your camera feed is never recorded, stored, or uploaded to any server.
Why Posture Monitoring Matters
Office workers, programmers, and students often spend 8+ hours sitting at a desk. Poor posture leads to back pain, neck strain, headaches, and long-term spinal issues. Most people don't realize they're slouching until the pain starts. This tool provides real-time feedback so you can correct your posture before it becomes a problem.
Key Features
- Real-time AI posture detection — Analyzes your body position at 30 frames per second using Google MediaPipe
- Three posture checks — Detects slouching (hunched shoulders), head forward lean, and shoulder tilt
- Audio alerts — Gentle two-tone chime when bad posture is detected (throttled to avoid spam)
- Posture score — Tracks the percentage of time you maintain good posture
- Session statistics — Total session time, good posture time, and alert count
- Adjustable sensitivity — Low, Medium, or High sensitivity for different body types
- Built-in Pomodoro timer — 25-minute work / 5-minute break cycles with session tracking
- 100% private — Camera feed processed locally, never leaves your device
How the AI Works
The tool uses Google's MediaPipe Pose Landmarker, a lightweight AI model that runs in your browser via WebAssembly. It detects 33 body landmarks (joints, shoulders, hips, etc.) from your webcam feed and analyzes three key posture indicators:
- Shoulder alignment — Measures the vertical difference between your left and right shoulders. Tilted shoulders indicate uneven posture.
- Head position — Checks if your nose (head) is too far forward relative to your shoulder line, a common issue for computer users.
- Torso angle — Measures the distance between your shoulders and hips. When you slouch, this distance decreases as your upper body curls forward.
The Pomodoro Technique
The built-in Pomodoro timer helps you combine posture awareness with productivity. Work for 25 minutes with focused concentration, then take a 5-minute break to stretch and rest your eyes. The tool tracks completed sessions and total focus time, giving you a complete picture of your work day.
Use Cases
- Programmers and developers — Code for hours without slouching
- Remote workers — Maintain office-quality posture at home
- Students — Study with proper posture during long sessions
- Gamers — Prevent "gamer's neck" during extended sessions
- Anyone with back pain — Build awareness of your sitting habits
Privacy & Security
Your privacy is our top priority. The webcam feed is processed entirely within your browser using WebAssembly-powered AI. No video frames are ever captured, recorded, stored, or transmitted. The AI model runs locally after a one-time download. Even if you disconnect from the internet after loading the page, the tool continues to work.
Browser Compatibility
Works in Chrome, Firefox, Edge, Safari (macOS), and Brave. Requires webcam access and WebAssembly support (available in 97%+ of browsers). A GPU-enabled device provides the best real-time performance.
Tips for Best Results
- Position your webcam at eye level for the most accurate detection
- Ensure good lighting — the AI needs to see your upper body clearly
- Sit 2-4 feet from the camera so your shoulders and head are visible
- Start with Medium sensitivity and adjust based on your posture habits
- Use the Pomodoro timer to take regular breaks and stretch
