Pilasophy

Overview
I’ve been doing pilates for a while, and one thing I kept noticing is that in larger classes, instructors can only do so much. People can move through an entire class with their form off simply because there isn’t enough attention to go around.
That observation stuck with me. What if everyone had their own personal instructor watching them, correcting them in real time, every single rep?
That’s Pilasophy: an AI pilates coach that watches you through your phone camera and corrects your form out loud, in the moment. No staring at a screen, no guessing if you’re doing it right, just cues as you move.
A personal instructor that’s always available and never runs out of time for you.
What I studied
How to do real-time pose tracking in the browser with MediaPipe Pose (33 keypoints at ~30fps) while keeping video on-device.
How to turn keypoint/joint alignment signals into coaching cues with a fast loop: detect → interpret → speak via text-to-speech.
How to iterate quickly on an app as a non-traditional builder using tools like Cursor, Claude Code, and Lovable.
What I found
Real-time feedback matters most when it’s delivered hands-free (voice) and within seconds of the movement, not after the session.
Privacy and latency are huge: keeping video on-device makes the experience feel safer and faster.
