Tips: light the backdrop evenly with no shadows or wrinkles, keep guests about 1 m in front of it, and ask them not to wear green. If edges look green, raise "How much green to remove" a little; if parts of people vanish, lower it.
The AI runs on this device; nothing is uploaded. It downloads about 10 MB the first time, then the browser keeps it. It works best with 1 to 4 people, from the waist up, within about 2 m of the camera, with good light. Hair edges and things people hold (props, flowers) can be cut off or look soft; a green screen gives cleaner edges when you have one.
Tap a background to make it the one that is picked first. Add your own as JPG or PNG; landscape 4 : 3 pictures of at least 1600 × 1200 px fit best.
