Spacely AI has earned serious credibility in the professional architecture space. With 580,000+ users including firms like Gensler, and deep integrations with SketchUp and Revit, it's built for professionals who live inside CAD tools. But not every designer — and certainly not every homeowner — works that way. Here's how HouseKraft compares for different use cases.
Quick Verdict
Choose Spacely AI if you already work in SketchUp or Revit and want AI visualization plugged directly into your existing 3D workflow. Choose HouseKraft if you want a simpler, faster, photo-first approach with a wider feature set, credit protection, and flexible pricing — no CAD skills required.

Where HouseKraft Wins
Zero learning curve. HouseKraft's chat-based interface means you describe what you want and the AI handles tool selection. Spacely AI's power comes with complexity — particularly when using the SketchUp/Revit plugins. If you're not already in that ecosystem, the onboarding is steep.
Photo-first workflow. Snap a photo, get a result. No 3D model needed. Spacely AI's best features require 3D models as input, which limits its usefulness for quick concept exploration or on-site client presentations.
Video from photos. HouseKraft generates walkthrough videos and 360° rotation from a single still photo. Spacely AI requires 3D models for similar output.
Credit protection. VLM validation + credits-back guarantee. Spacely offers neither.
Flexible pricing. PAYG from $10 with no subscription lock-in. Spacely AI is subscription-only.
Where Spacely AI Wins
SketchUp and Revit integration. If your workflow lives in SketchUp or Revit, Spacely AI's plugin integration is a genuine advantage. You can render AI visualizations directly from your 3D models without exporting to a separate tool. HouseKraft doesn't integrate with CAD software.
Enterprise credibility. With 580K+ users including major firms like Gensler, Spacely AI has proven itself in large-scale professional environments. HouseKraft is newer and building its professional user base.
Lower entry price. Spacely AI starts at approximately $13/month — though HouseKraft's free tier and PAYG option may cost less for lighter usage.
The Bottom Line
Spacely AI is built for professionals who already work in 3D CAD environments. If that's you, its SketchUp/Revit plugins are genuinely useful. For everyone else — homeowners, designers who work from photos, architects who want quick concept visualization, real estate agents — HouseKraft's photo-first approach, wider feature set, and zero learning curve make it the more accessible and versatile choice.
