What our research says

RoomGPT

The fastest way to answer "what would this room look like in a different style", and the no-expiry credit model suits people who use it twice a year rather than twice a day. Treat the output as a mood board, not something a contractor can build from.

Pros

  • Credits are a one-time purchase with no expiry, confirmed in the vendor's own fulfillment policy
  • Single-photo input with no modelling, measuring or scene setup
  • Turnaround is fast enough to iterate live in front of a client

Cons

  • Output is a render with no dimensions, product links or shopping list
  • No API, no batch upload and no team workspace
  • Run by a single developer, so support and roadmap rest on one person
  • A discount code is permanently displayed on the site, which makes the list price hard to take at face value

Spacely AI

Aimed squarely at practising architects and interior designers rather than homeowners playing with room photos — the CAD plugins and geometry preservation are the whole point. If you just want to see your living room in a different style, cheaper toys do that.

Pros

  • Preserves original geometry and materials, which is the difference between a render and a style transfer
  • Native SketchUp extension plus Revit, AutoCAD and Rhino integrations keep the file workflow intact
  • Free tier gives 40 credits with commercial licence and no watermark, which is unusually generous
  • Credits from top-ups stack and never expire

Cons

  • Subscription prices are rendered client-side and effectively hidden from the static pricing page
  • API access is an Agency-tier add-on, not available on entry plans
  • Everything is credit-metered, so iterating on a single image eats budget
  • Small company with roughly $1M raised — a real vendor-continuity consideration for studio workflows
