What do I need to get started?

A photo of your room from any phone — straight-on, in daylight if you can. No special hardware, no measuring equipment.

Every account starts with 2 free redesigns, and each design or regeneration uses one credit. The Think Decor plan adds 20 credits every month — 69p for your first month, then £4.99.

Mantha is the design intelligence inside Think Decor. Give it a photo, a style and a few words about what you want, and it restyles your actual room — keeping the walls, windows and layout you already have.

Can I change what Mantha AI creates?

Yes. Regenerate for a new variation, or describe what to change — "lighter floors", "a green velvet sofa" — and Mantha refines the same photo. Every design is saved to your library to compare and download.

Can Think Decor measure my room?

Not yet. Room scanning with measured floor plans — and PDF, SVG and CAD exports — is in development. Today, Think Decor redesigns rooms from a photo.

Can I cancel any time?

Yes. Manage or cancel your plan from Settings in your account, and it stays active until the end of the period you have already paid for.

Mantha

What is Mantha? The design intelligence that reads your room like a decorator.

01It finds the structure.
Mantha looks at your photo the way a designer would: it traces the walls, the floor and the edges of everything standing on it.
02It reads the light.
It works out where the window light comes from and where the shadows fall, so anything new sits in the same light as the rest of the room.
03It changes only what you choose.
New paint, flooring or upholstery is drawn in the right perspective. The layout, the window light and the shadows stay exactly where they were.
