From planning to a picture
Try the direction in your actual room.
Each suitable result can become an editable design brief. Carry a style, palette, furniture choice or material direction into Studio, review the settings, then generate when ready.
Calculations use your measurements. An AI image helps compare appearance; it does not verify exact dimensions, paint quantity or installation.

Yes. Calculations, the quiz and photo palette extraction need no account. AI previews in Studio use the normal login and credit system.

You enter your measured dimensions and product label values. The tools do not measure a room from a photo.
Do results automatically create a design?
No. You review a brief, confirm it in Studio and choose Generate Design yourself.
