What's happening biomechanically — and three drills that fix it.

Form Detective is an AI biomechanics coaching tool for powerlifters. Upload a video of your squat, deadlift, or bench press — trimmed to your working set — and get a precision rep-by-rep breakdown of your technique, flagging exactly where and why your form breaks down.
Our neural engine performs a frame-by-frame biomechanical audit, reconstructing your movement in 3D space using pose estimation. It calculates joint angles, bar path, and movement patterns across every rep — then generates a coaching report with specific technique cues for each one.
Form Detective currently supports the squat (high bar and low bar), deadlift (conventional and sumo), and bench press. All three powerlifting competition lifts are covered.
Yes — you get one free analysis with no account required. Paid credits are available for ongoing use, with no subscription required and no expiry on purchased credits.
No special equipment needed. A standard phone camera works. For best results, film from the side at roughly hip height, about 8–10 feet away, in landscape mode. See our full filming guide →
Form Detective analyzes every rep individually with precise joint angle data — not a single impression of the set. You get rep-by-rep breakdowns showing exactly when fatigue or technique changes, which is difficult for any coach to track visually in real time. It's available instantly, any time, without scheduling.
