Does it repaint my photo with AI?
It places flat sample squares on your photo, the same way a painter brushes test patches on a wall, so the wall's own texture and the light falling across it stay visible through the color. The AI reads paint can labels and names color schemes; every quantity and every color on screen is computed on the phone.
Do I need an account, a key or a server?
Rooms, photos, colors and estimates live in the phone's encrypted store and every screen works without a key. Add your own AI key for label scanning and scheme ideas, or deploy the included Laravel key proxy so the key stays on your server.
Can I move to a new phone?
Yes. Settings copies every room, wall, color and estimate as one JSON envelope, and pasting it on the new phone brings them back exactly. Photos stay on the device they were taken on.
