Before you ask
What can I do without an account?
Answer the questions and see the floor plan for every level. Your brief and selected plan are kept on this browser when storage is available. This is not a cloud backup. Own-project downloads require eligible account access.
What does the free account add?
Your houses are saved, so you can come back to them, and you can walk through each one in 3D.
What is a photoreal house?
We build your house in full on our servers: real materials, furniture, every light switched on, and sunlight bouncing through the rooms. It takes about half an hour. You get an email when it is ready, with a walkthrough you can explore and a set of photographs, all kept in your account.
What if I need more than 3 photoreal houses in a month?
The allowance resets every month on your billing date. Unused houses do not roll over.
How does that compare with hiring a drafter?
Custom house plans typically cost $2,000 to $10,000 in the US (HomeGuide, 2026). Keystone AI gives you a concept set to start that conversation with, not construction documents.
How do I cancel?
