Frequently Asked Questions
Can AI replace an interior designer?
No. AI generates options fast, but design expertise, client relationships, contractor coordination, and spatial problem-solving still require a trained designer. AI is a tool that makes designers faster, not obsolete.
What is the best free AI tool for interior design?
Homestyler and RoomGPT are both free. RoomGPT is faster for style exploration, Homestyler is better for full floor plan layouts.
Can I use AI design images in client proposals?
Yes, with a disclosure that images are AI-generated concepts. Most clients appreciate seeing a visualization early — it speeds up approval and reduces revision rounds.
