ANALYZ
HUMAN MOVEMENT. MACHINE PRECISION.
AI That Scores Human Movement From Video.
We decoupled physical kinematics from heavy pixels. Our specialized Action Quality Assessment model scores dance kinematics in 15 milliseconds — delivering full cloud video evaluation in 2–3s on GPU at 1/1,000th the compute cost of multimodal LLMs.
Full 30–60 FPS temporal kinematics. No 1 FPS downsampling loss.
15ms model scoring (< 2.5s full video on GPU).
Trained on proprietary commercial casting outcomes across thousands of gygs.
Your video. Its motion. One timeline.
Upload an audition or analyse a sample. Track the process, then inspect body and face landmarks at any moment.
Expression values appear when the face is tracked by the analyser.
88.0th percentile
Physical measurements
Peak extension: 162.0 deg
Arm difference: 18.0 deg
Torso tilt variation: 3.20 deg
Expression range: 0.380
New uploads replace the preview and its tracking. The source and skeleton share playback controls.
Why Multimodal LLMs Fail at Human Movement
General vision models describe what they see. Analyz measures what actually happened, frame by frame.

How It Works
01 / SENSE
Decoupled Physical Sensing
Decode video into 33-point 3D skeleton coordinates, audio drum onsets, and 52 facial blendshapes. Discard heavy pixels.
02 / MEASURE
Physical Kinematics Engine
Compute exact millisecond beat phase-locking, bilateral limb symmetry, and core balance stability.
03 / ASSESS
Action Quality Assessment (AQA) Network
Evaluates physical execution against real commercial hiring outcomes to output a calibrated quality score and population percentiles.
Developer API
A simple REST interface for commercial casting, performance platforms, and movement applications. Built to run on basic CPUs and phones.

Stop guessing. Start measuring.
Human movement deserves more than a multimodal guess.
