SitSense is an AI-powered posture tracker and coach that uses your webcam to analyze posture in real time — no wearable devices, hardware, or app downloads required. Built on Google's MediaPipe computer vision framework, SitSense tracks 7 core posture metrics including forward head posture (tech neck), neck angle, trunk alignment, and shoulder slope, delivering instant feedback and coaching directly in your browser. Designed for remote workers, software engineers, students, and anyone who spends long hours at a desk, SitSense detects the subtle alignment changes that cause neck pain, back tension, and mental fatigue — and corrects them before discomfort builds. Analysis of 540+ hours of real user posture data shows most strain begins with small shifts that go unnoticed without real-time tracking. Unlike wearable posture correctors like Upright GO 2 or the discontinued Lumo Lift, SitSense analyzes full upper-body posture through your existing webcam with over 90% accuracy. All video processing happens locally on your device — no video is ever recorded, stored, or transmitted. Features include real-time posture scoring, personalized AI coaching, streaks, leaderboards, daily goals, and session analytics. Works on Chrome, Firefox, Safari, and Edge on Windows, macOS, and Linux. Free 3-day trial, then $34.99/year.

RepDB is a one-time-purchase exercise dataset for developers building fitness and workout apps — not a subscription, not a rate-limited API. You download the data once and own it: JSON (and SQLite on the higher tier), WebP images, and full EN/DE/ES translations, with no per-request billing and no dependency on our servers staying up.

A free tier includes 250 exercises with flat-style 512×512 images, attribution-licensed for commercial in-app use. The Starter tier ($199) adds the full catalog in classic white-background style. Standard ($399) adds transparent 1024px images, looping animations, exercise relations (similar/progressions/regressions), workout templates, and embeddings — exclusive to that tier.

Every exercise includes muscle-group highlighting, equipment/muscle icons, MET values, and safety/goal tags. Compared to GIF- or JPG-based competitor APIs, RepDB images are transparent WebP with no watermarks, so they drop into any app UI without a white box around them.
