Three ways to get a plan, and where each one’s numbers come from
Every tool below calls itself a floor plan generator. They do different jobs, and the difference only shows up when a sofa has to fit through a door.
Generate a plan from a description
You describe the home: how many rooms, roughly how big, what has to sit next to what. The generator returns a plan that follows those rules, because it has seen enough homes to know kitchens sit near dining rooms and bedrooms want distance from the front door.
Early options for a new build or an extension, and for testing a brief before anyone draws properly. Useless for measuring a room you already live in.
Chosen. The dimensions are the ones you gave it, or the ones it picked. That is right for a home that is not built yet, and it means the plan describes a building, not your building.

Turn a plan you already have into an editable one
You drop in the estate agent’s drawing, a builder’s PDF or a photo of a printed plan, and the tool traces it into walls you can move and measure. For an existing home, this is usually the fastest route to a plan you can work on.
Skipping the redraw when you hold a dimensioned plan. If the drawing has no numbers on it, no tool can invent them, and you are back to a tape measure.
Borrowed. It reads the dimensions printed on the drawing rather than deriving them. Planner 5D says so in its own help centre: plans "must include dimensions; without them, we cannot reproduce the plan while maintaining the desired dimensions".

Scan the room with a phone
You walk the room with the camera, or the LiDAR sensor on a recent iPhone Pro, and the app builds the plan from what it sees. The only method of the three that goes and measures.
A room with no plan at all. Check the two or three walls a piece of furniture depends on with a tape before trusting the layout to them.
Measured, within the error of the scan. That error is small, and furniture fit is still decided in centimetres.

The generators on page one, compared
Entry prices read off each vendor’s own pricing page. Almost all of them meter use in credits, so the free option is an allowance, not a plan you keep.

| Floor Plan AI | Free credits on sign-up | $9.99/mo, billed yearly | Generated plans, renders, DXF | Credit-metered: 200 generations a month on Starter |
| Home Design AI | Free credits to claim | $9.99/mo, billed yearly | Generated plans and room designs | Tiers and prices identical to Floor Plan AI |
| Maket | 50 one-time credits | $20/mo | Generated plans, plan upload, renders | Free plan generates single-floor plans only |
| Planner 5D | About half the catalogue | $19.99/mo | Recognised plans, 3D rooms | Recognition takes 10 minutes to 24 hours |
| Ideal House | — | $19/mo | Floor plans and room visuals | Image-first; credits per generation |
| Decato | Free on your own AI key | $20/mo | Generated or traced plans, furnished with real products | Mac and Windows; plans end in a priced shopping list |
Floor Plan AI and Home Design AI publish the same three tiers at the same prices, to the cent: $9.99, $24.99 and $49.99 a month on yearly billing. If you are choosing between those two, price will not decide it.
A layout can look right and be wrong, and the eye will not catch it
We can show this on ourselves. Building the four studio layouts on another page of this site, every arrangement was placed by eye first and then drawn to scale and run through a clearance check. Two of the four had furniture standing inside the front door’s swing.
They looked completely fine. A door swing is a quarter-circle roughly ninety centimetres across that nothing draws unless you ask it to, and it is the single most commonly ignored piece of geometry in a room. A generated plan has exactly the same blind spot, for the same reason.
What happens after the plan
Most generators stop at the drawing. Decato treats the plan as the start: generate one from a description, or trace one you already have — an agent’s listing image, a builder’s drawing, a photograph of a printed plan — and correct the walls by hand wherever they matter.
After that those numbers are the truth everything is measured against. Furniture is matched to real in-stock products and refused if it does not clear the walkways and the door swings, and what comes back is a priced list rather than a picture to interpret.
Correcting the traced walls is a real step, not a formality. The plan is only as good as the drawing it came from, which is the whole point of this page. Mac and Windows; planning runs free on your own ChatGPT, Claude or Gemini key.
Common questions
Can Decato generate a floor plan from a description?
Yes. Describe the home — how many rooms, roughly how big, what should sit next to what — and it draws a plan with walls you can move and measure. If you already have a plan, drop in the image or PDF instead and it traces that. Either way, the next step is furnishing it with real products that fit.
Is there a free AI floor plan generator?
Several start free, but free usually means a credit allowance rather than unlimited use. Maket gives 50 one-time credits, Floor Plan AI and Home Design AI give sign-up credits, and Decato is free for planning if you connect your own ChatGPT, Claude or Gemini key (Checked September 2026).
Can AI generate a floor plan of my actual house?
Not from a description alone. A generated plan follows the numbers you give it, so it describes a building rather than measuring yours. For a home that already exists, trace a plan you have or scan the rooms with a phone, then check the walls that matter with a tape.
Are AI floor plans dimensionally accurate?
It depends where the numbers came from. A generated plan uses the dimensions you chose. A traced plan is as accurate as the numbers printed on the drawing: Planner 5D states it cannot keep dimensions the source does not carry. A scanned plan is genuinely measured, with the small error any scan has (Checked September 2026).
Is there an AI floor plan generator for Mac?
Most generators run in a browser, which works on a Mac. Decato is a native desktop app for Mac and Windows: it generates or traces the plan and then furnishes it with products you can order, checked against the walls and door swings. A Windows version is planned.
