This is the same engine the product uses. Nothing is stored, no account is needed, and the photographs never leave this browser — the pose model runs on your device and only the outline is sent for the arithmetic.
If the numbers look wrong
Look at the outline drawn over your photographs. Almost every bad reading is a bad outline, and it is visible: a coat included, an arm merged into the torso, a leg lost against a dark floor. Close-fitting clothes, a plain wall, light from the front, and the whole body in frame fix nearly all of it.
The one thing you cannot see is a wrong height. In the product there is a tape anchor for exactly that. More about how this works.
