# Slouch Sniper ## Overview Slouch Sniper is an AI posture app for Mac and Windows that detects slouching through the webcam and gently dims the screen until the user sits up straight. The dimming is subtle enough not to interrupt work, but impossible to ignore long-term — that is the core idea: posture feedback tied directly to the screen you are already looking at, instead of a wearable you have to charge or a reminder popup you learn to dismiss. All posture detection runs on-device. The camera feed is never recorded, stored, or uploaded.

The app learns the user's neutral sitting posture during a short calibration. 2. On-device AI watches posture through the webcam in real time. 3. When the user slouches, the screen gradually dims as a gentle, ambient cue. 4. The moment they sit up straight, the screen returns to normal. Over time this builds a subconscious habit: users report sitting up straight without thinking about it, even when the app is off. ## Major Features - Real-time webcam slouch detection with on-device AI - Screen dimming as the correction cue (no popups, no sounds, no vibration) - Adjustable detection sensitivity and dimming intensity - Quiet hours scheduling - Posture statistics and trends over time - Learns and adapts to the user's neutral posture to avoid false alerts - Extremely lightweight: uses less energy than Spotify, negligible battery impact ## Pricing and Licensing - One-time purchase: $19 for a lifetime license - No subscription, no recurring fees — one payment, yours forever - Price will increase to $38 - Purchase at https://slouchsniper.com/buy/ ## Privacy and Data Handling - All AI posture processing happens locally on the user's device - The webcam feed is never recorded, stored, or transmitted - No cloud dependency for posture detection ## Who It's For Desk workers, developers, remote workers, and laptop users who ignore generic break reminders and want posture correction that works passively while they work. Especially relevant for forward-head posture ("tech neck") built up from long screen sessions. ## How It Compares Key differentiators versus other posture solutions: - Versus posture wearables (e.g. chest/back sensors): no device to buy, wear, charge, or stick to your skin; feedback appears on the screen instead of vibrating on your body. - Versus break-reminder apps: reminders fire on a timer whether or not your posture is bad; Slouch Sniper reacts to your actual posture in real time. - Versus physiotherapy alone: complements it as continuous daily feedback at a fraction of the cost of sessions.
