FAQ

Can AI interior design tools suggest specific furniture to buy? Most just show visuals. Some newer tools (like Modsy, now part of other platforms) link to purchasable items. Otherwise, take the AI render to a furniture store and match it yourself.

Is AI interior design accurate enough to plan real renovations? For concept and style direction, yes. For actual measurements and technical planning, always work with a licensed designer or contractor.

Can it work for commercial spaces like offices? Yes. RoomGPT has an “Office” room type. For corporate spaces, Spacely AI and custom Midjourney workflows give more professional results.
