InteriorAI vs RoomGPT
Both restyle room photos; the split is subscription volume versus one-off credits. InteriorAI (built by indie developer Pieter Levels) sells monthly subscriptions: Pro $49/month for 1,000 designs, Premium $99/month, Ultra $199/month (per Oct 2026 pricing), with no advertised free plan. RoomGPT gives 3 free renders and sells one-time credit packs ($9 for 30, $19 for 100, $29 for 200) that never expire. If you render hundreds of rooms, InteriorAI's subscription is cheaper per render; for one renovation, RoomGPT's credits fit better. There is no measured quality winner in this review.
| Decision point | InteriorAI | RoomGPT |
|---|---|---|
| Best suited to | Homeowners reimagining a room, exterior or garden before spending on renovation.; Real-estate sellers furnishing empty homes with virtual staging. | Homeowners, renters and real-estate agents who want a quick, cheap style preview of a room. |
| Plans and cost | The page read lists monthly plans at $49, $99 and $199 per month, and yearly billing at $29, $49 and $99 per month billed yearly ($349, $599 and $1,199), described as over 50% cheaper or 6+ months free against monthly pricing; a Premium upgrade adds $60 more per month for 5,000 interiors per month with priority access. The page read names no currency for these $ amounts, so no charge fact is recorded. | Free: 1-3 generations; credit packs $9/30, $19/100, $29/200 one-time, non-expiring (official site, October 2026). |
| Limitations | The tool restyles spaces visually and does not change construction, so structural redesigns need a professional.; Premium generation capacity costs extra per month on top of the base plan. | AI outputs are creative visualizations, not construction specs - verify dimensions, materials and costs separately. Do not confuse roomgpt.io with RoomsGPT, a different product with similar naming. Fr |
Use the same input

What a successful result must preserve
Both renders must start from the same photo and style, and the comparison must report the price of one finished render on each side.
