Best AI interior design apps in 2026
Interior AI, InteriorAID, RoomGPT, and Roomersive compared: who stills, who walks you through, who lets a household vote, and what each one costs to start.
Nearly every AI interior design tool still starts the same way: upload a room photo, pick a style, get a restyle back. 3D from one photo is no longer unique. Interior AI and InteriorAID both ship a World Labs walkthrough. The useful split is what happens after the still: a catalog to browse, a designer’s bench, a free one-shot, or a vote with the people you live with.
How we evaluated
- Output — a still, a 3D walkthrough, a clip, or a poll
- Who it’s for — homeowner, renter, designer, or listing agent
- Try-before-account — can you see your room before you create a login
- Starting price — the first dollar, not the enterprise tier
Prices move. Check each site before you buy; the rows below are what we could stand behind on 21 September 2026.
The shortlist
| # | Tool | After the still | Try with no account | Starting paid price | Best for |

| 2 | InteriorAID | World Labs splat + short clip | Small token grant after signup | About $10/mo | Designers iterating concepts |
| 3 | Interior AI | Large style catalog + World Labs 3D | Account-first | Pro about $49/mo | Fast stills in many styles |
| 4 | RoomGPT | Still only | One free render | Credit packs | A single quick redesign |

| 6 | Collov AI | Still | Varies | $19–127/mo | High photo-credit volume |
Roomersive sits first for the job this site is built around — decide together, then step inside. That is not the same as “best at 3D.” InteriorAID and Interior AI both walk you through a restyle. If you want the widest catalog of stills, Interior AI still wins. If you start from a sketch or CAD, InteriorAID’s bench wins.
What each one is actually for
Roomersive. One photo, a named style, a “which one?” poll the people you live with can answer with no account, then a walkthrough of the winner. Famous rooms (Van Gogh’s bedroom, a haunted parlour) are free to browse; Save clip records an 8-second walk-in from that viewer. Your own photo: one guest restyle, a 3-day trial of restyles, then a $9 pack or a plan if you want 3D. Walkthroughs are the upgrade, not a monthly gift. See Interior AI vs Roomersive and InteriorAID vs Roomersive.
InteriorAID (interioraid.app). A designer’s bench: SketchUp, inpainting, object removal, then a splat or a 5–15 second clip for a client. Hobbyist is cheaper per month than our Starter. There is no household poll.
Interior AI (interiorai.com, levelsio). The style catalog people keep a subscription for, now with a World Labs “3D Vision” walkthrough. Account-first. Paid plans start much higher than a $9 pack.
RoomGPT. One free still, no account. The category’s original try-before-signup. No 3D, no poll.
REimagine Home and Collov. Staging and volume stills. Different buyer.
When to choose which
- You live in the room and someone else has to like it — Roomersive. Start at Try it on your room or the style quiz.
- You are presenting options to a client from a sketch — InteriorAID.
- You want twenty directions as stills, fast — Interior AI.
- You want one free picture and nothing else — RoomGPT.
A visit that does not convert is not acquisition. If a still is the deliverable, several tools on this list will do it in ten seconds. If the deliverable is “we agreed, and we stood in it,” start with your own photo.
