Live form correction
Elbow drift, back rounding, shallow depth: the moment your form breaks, you hear it. Bad reps don't count. Good reps stay silent so you can focus.
Stream AI watches your set through any camera, counts every rep, and calls out form errors the moment they happen. No trainer, no wearables, no guesswork.
Setup takes 30 seconds. Then just work out. Stream AI does the rest.
Open the app, pick your exercise, and line up the side view with the on-screen guide.
The engine reads your joint angles, body alignment, and rep phase live, frame by frame, as you lift.
Voice cues call out errors the moment they happen. After the set: form scores, clean-rep counts, and strength progress.
Built from biomechanics research. Coached like a personal trainer.
