AI Interior Design: Pretty Renders vs Real Plans

Upload a photo of your living room, pick "Scandinavian", and thirty seconds later you have a beautiful image of a room that cannot exist. The sofa is 2.6 metres long in a 2.1 metre alcove, the window has moved, and there is a radiator where the door opens.

That is not a flaw in one product. It is the defining split in this category, and knowing which side of it you need saves both money and a wasted afternoon.

Two completely different products

Restylers take a photo and repaint it. They are image models: they see pixels, not rooms. The output is a mood board — genuinely useful for deciding you want warm wood and dark green before you commit, and useless as something to hand a carpenter.

Planners work from measurements. You draw or upload a floor plan, place real furniture with real dimensions, and the render comes out of a model of the actual space. Slower to set up, and the result is a thing you can build from.

Most of the frustration people have with AI interior design is buying the first when they needed the second.

What they cost

Interior AI is the best-known restyler. You "upload a photo of your interior and transform it completely", and it handles interiors, exteriors and gardens. Pricing is Pro at $49 a month or $29 billed yearly for 1,000 designs a month, Premium at $99 or $49 yearly for 5,000, and Ultra at $199 or $99 yearly for 25,000. There is no free tier, which is the main objection — you are paying before you know whether the output suits your room. It is built by Pieter Levels, the indie developer behind Nomad List and Photo AI, which tells you something useful about its shape: fast, focused, one person's product rather than a design suite.

Planner 5D is on the other side. Free gives unlimited projects with access to half the furniture catalogue — a genuinely usable free tier rather than a trial. Premium is $19.99 a month or $59.99 a year and opens the full 10,000-item catalogue plus 100 monthly AI Studio credits. Professional is $49.99 a month or $399.99 a year with unlimited 4K renders and 1,000 monthly credits. Its AI pieces sit inside a real design tool: it can take an uploaded floor plan and "instantly turn it into a 3D project", and import 3D models from photos.

Note what the annual pricing does to the comparison. Interior AI's cheapest annual rate is $29 a month and gives you restyled images. Planner 5D's Premium is $59.99 a year — about $5 a month — and gives you a measured 3D model. If you are choosing on price, they are not close. You are paying Interior AI for render volume, which only matters if you are producing listings or client options at scale.

The generic image generators also do this

You do not necessarily need a dedicated tool. Midjourney and the other image models will produce interior visualisations from a text prompt, and for pure inspiration they are often better-looking than the specialists. What they will not do is start from your room — you get a beautiful generic space rather than your space restyled. For mood-boarding before you have a floor plan, that is fine and you may already pay for one. Our best AI image generation tools covers the options, including a free list.

Virtual staging for a property listing is the one case where restyling genuinely is the product, because the buyer is being shown a possibility rather than a plan. Check your local disclosure rules before publishing an AI-staged photo in a listing.

What AI interior design cannot do

They do not know building regulations, structural walls, where your plumbing runs, or what your society or landlord permits. A render showing a kitchen island where a load-bearing column stands is not warning you about anything.

They do not measure. A restyler has no idea how large your room is. If the image is driving a purchase decision, measure the actual alcove yourself and check the actual product dimensions.

They invent fittings you cannot buy. The light in the render is frequently not a real product. For anything you intend to actually source, treat the image as a brief for a search, not a shopping list.

They will not replace a designer on anything structural. Restyling and furniture arrangement is one job; moving a wall is a different one with consequences.

Which to pick

You want ideas, fast, for your own room. Interior AI, monthly, and cancel. Budget one month and generate aggressively; the value is front-loaded and there is no free tier to test with first.

You are actually renovating. Planner 5D free, then Premium at $59.99 a year if you need the full catalogue. Measured 3D is the only output a contractor can work from.

You just want to see styles. Midjourney or any image generator you already pay for. No dedicated subscription needed.

You are staging listings. Interior AI's volume tiers are built for exactly this, and this is the one use where a photorealistic impossible room is the deliverable rather than a problem.

FAQ

Is there a free AI interior design tool?

Planner 5D has a real free tier — unlimited projects and about half the furniture catalogue — rather than a trial. Interior AI has no free tier at all. For inspiration rather than planning, free image generators do the job without any interior-specific subscription.

Can AI redesign a photo of my actual room?

Yes, that is exactly what restylers like Interior AI do: you upload a photo and it transforms the space while keeping the shot. What it cannot do is respect your dimensions, because it is working from pixels and has no idea how big the room is.

How much does Interior AI cost?

Pro is $49 a month, or $29 a month billed yearly, for 1,000 designs monthly. Premium is $99 or $49 yearly for 5,000, and Ultra is $199 or $99 yearly for 25,000. There is no free plan.

Can I give an AI render to a contractor?

Not a restyled photo — it has no measurements and may show things that cannot be built. A measured 3D project from a tool like Planner 5D is a different matter, and that is the reason to use a planner rather than a restyler if work is actually happening.

Will AI interior design replace an interior designer?

For arranging furniture and choosing a palette it genuinely reduces the need for one. For anything structural, anything involving regulations, and anything where being wrong is expensive, the render is a conversation starter and not a plan.
