Interior AI

Interior AI (interiorai.com) is one of the best-known English-language AI interior design tools. It offers two modes: a creative redesign mode (which can change walls, floors, and ceilings) and a Virtual Staging mode (which preserves the room structure and only swaps furniture and decor).

Strengths:

• 40+ interior design styles
• Virtual Staging particularly suited to real estate professionals
• Interactive 3D flythroughs of generated spaces

• Relatively expensive: from $29/month or $249/year
• No explicit GDPR compliance for EU users

Best for: Real estate agents and interior designers who need professional virtual staging in English, and users who want 3D visualization.

Pricing: Pro: $29/month or $249/year; Teams: $299/month (up to 10 users)

Planner 5D

Planner 5D (planner5d.com) is not a photo-to-redesign tool — it's a full 3D room planning application with AI features built in. It suits users who want to actively design floor plans and furnish rooms in 3D, not just apply a style filter to an existing photo.
