Start from the photo you already have. A photo of a house, a room, a yard or an empty listing belongs in the Home Design Studio. A garment, a shoe, a piece of jewelry or a product on a white background belongs in the Fashion Studio. If you have no photo at all and just need something people can scan — a link, a WiFi password, a menu, a contact card — that is the QR Studio.
You are never locked into one. Studios share your account, your credits and your history, and you can move between them at any time. If your need does not fit any of the three, the full tool directory is the better starting point — and anything missing there can be generated as a new tool on demand.
