Both use AI. Both support multiple brands. But they're built for different jobs. Muro focuses on interior walls with photorealistic lighting preservation. Housepaint AI (Repaint) leans harder into exteriors with multi-surface detection.
If you're choosing between the two, here's what actually matters.
The basics
| Feature | Muro | Housepaint AI (Repaint) |
|---|---|---|
| Colors | 27,000+ from 14 brands | 17,500+ from 6 brands |
| Technology | AI (Gemini) — photorealistic generation | AI — surface-aware generation |
| Focus | Interior walls | Exterior + interior |
| Platform | iOS (iPhone & iPad) | Web + iOS + Android |
| Pricing | Subscription (weekly/monthly/annual) | Freemium with credits + Pro subscription |
| Languages | English, German, Polish | English |
| Quality tiers | Standard (1K), HD (2K), Ultra (4K) | Single output quality |
| Batch mode | Yes — up to 12 colors at once | No |
| Color matching | Yes — from any photo | Limited |
Where Muro wins
Bigger color database — by a lot
27,000+ colors vs 17,500. That's not just a number difference. Muro includes regional European brands that Housepaint AI doesn't touch — Caparol, Brillux, Sto, Alpina, Jotun, Farrow & Ball's full collection, plus Polish brands like Śnieżka and Dekoral. If you're not in the US, Muro's database is far more relevant.
Interior wall specialization
Muro is built specifically for interior walls. The AI understands how light falls across a room, how shadows interact with wall color, and how to preserve architectural details. It's a scalpel for one job, not a Swiss army knife.
Batch mode
Pick up to 12 colors, see all of them on your wall in one session. When you're narrowing down a shortlist, this saves enormous time. Housepaint AI doesn't offer this.
Quality options
Three output tiers up to 4K. When you want to zoom in and see texture detail, Ultra mode delivers. Housepaint AI has a single output quality.
Multilingual
Full support for English, German, and Polish — both the app and the color database are localized. Housepaint AI is English-only.
Where Housepaint AI wins
Exterior visualization
If you're painting the outside of your house, Housepaint AI is stronger. It detects siding, shutters, trim, garage doors, and other exterior surfaces automatically. Muro focuses on interior walls.
Multi-surface detection
Housepaint AI can identify and color different surfaces independently in one image — walls, doors, trim, shutters. Muro lets you select wall zones, but it's designed around wall surfaces specifically.
Web + Android
Housepaint AI works in a browser and on Android. Muro is iOS-only. If you're on Android or want to work on a desktop, Housepaint AI has more flexibility.
Free tier
Housepaint AI lets you start free with credits. Muro requires a subscription after a limited trial. If you only need one or two visualizations, Housepaint AI's credit system might be cheaper.
The AI quality question
Both apps use AI to generate results rather than flat color filters. But the approach differs.
Muro uses Gemini-based generation optimized specifically for wall surfaces. It's trained to understand how paint interacts with room lighting — the warm glow from a window, the shadow behind furniture, the subtle color shift in a corner. The result looks like someone actually painted the wall and took a new photo.
Housepaint AI's AI engine is broader — it handles siding, brick, wainscoting, and multiple surface types. That versatility comes with tradeoffs in per-surface accuracy. Interior wall results tend to look good but less nuanced in terms of lighting preservation.
Bottom line
Choose Muro if: you're painting interior walls, want the largest color database (especially European brands), need batch mode to compare multiple colors fast, or want 4K quality output.
Choose Housepaint AI if: you're painting the exterior of your house, need multi-surface visualization (siding + trim + doors), want web/Android access, or prefer a pay-per-use credit model.
For most people deciding on a wall color for their living room or bedroom — which is the most common paint project — Muro delivers more realistic interior results with a much deeper color library.
