Best AI exterior design apps in 2026

Most AI design apps focus on interiors. Exterior design is harder — the AI has to handle rooflines, siding materials, window frames, driveways, landscaping, and natural light that changes throughout the day. A badly-generated exterior looks wrong immediately because we see houses from the outside every day. Our eyes are calibrated for it.

I tested 6 apps that claim to do exterior home design. I uploaded the same ranch-style house photo to each and asked for a modern exterior makeover. The results ranged from convincing to absurd — one app added a second story to a single-story house.

Quick comparison

1. Remodel AI

A ranch-style house with a complete curb-appeal overhaul. Dark charcoal siding replaces the faded original. White trim frames every window. A matte black front door adds contrast. Updated landscaping with ornamental grasses and pathway lighting replaces the bare lawn. The roofline, windows, driveway, and garage all remain exactly as built.

What it does: Upload a photo of your home's exterior and choose from 11 architectural styles. The AI redesigns the facade — siding, trim, door, windows, roofing, and landscaping — while preserving the actual structure. Specialized garden and landscape tools let you also redesign the yard separately.

Why it's #1 for exteriors: Most competitors stumble on exterior design. They add windows that don't exist, change the roofline, or generate a house that's clearly a different building. Remodel AI consistently preserved the original structure in our testing — same roof pitch, same window count, same garage placement. The siding, color, landscaping, and details changed. The house didn't.

Pricing: 3 free designs (works for exterior), then $39.99/year unlimited.

2. Renovate AI

Renovate AI handles both exterior facades and landscape design. Its cost estimation feature is useful here — exterior projects (new siding, roofing, landscaping) can range from $5,000 to $50,000, and having even a rough estimate helps frame conversations with contractors.

Pricing: Free tier available, then subscription.

Platforms: iOS and web.

Best for: Homeowners who want both the visual and a rough cost ballpark for exterior renovations.

3. DecAI (Interior DecAI)

DecAI covers all three surface types — interior, exterior, and garden — in one app. Exterior quality is acceptable, though not as precise as Remodel AI on structural preservation. The $49.99 lifetime price is attractive for a one-time exterior project. Available in 31 languages, making it the best option for non-English speakers planning exterior renovations.

Pricing: $5.99/week, $29.99/year, or $49.99 lifetime.

Platforms: iOS and web.

Best for: Non-English speakers or budget-conscious users who prefer paying once.

4. Home AI

Home AI includes exterior design in its free tier (2 designs/day with ads). The guided wizard walks you through room/space type selection. Exterior results are inconsistent — some outputs change the number of windows or alter the roof shape. Worth trying for free, but verify the output against your actual house before showing it to a contractor.

Pricing: 2 free/day with ads, then subscription.

Platforms: iOS and Android.

5. AI Remodel (by PulseApps)

AI Remodel has dedicated exterior and garden tools. The garden redesign is a standout — it handles front yards, patios, and backyard landscaping better than most competitors. The facade tool is less reliable on large homes with complex rooflines.

Pricing: $9.99/week, $64.99/year.

Platforms: iOS and Android.

Best for: Users who specifically want garden and landscaping AI alongside basic exterior restyling.

6. Interior AI

Interior AI does not support exterior design. Including it here to prevent confusion — if you need exterior AI design, look at the other options on this list.

Tips for better AI exterior design results

• Photograph from the street — stand across the street and capture the full facade
• Include the roof — most exterior redesigns change roofing material or color
• Shoot in daylight — natural light gives the AI better data for material rendering
• Include landscaping — the front yard is part of the curb appeal. Don't crop it out
• Try at least 3 styles — modern, craftsman, and farmhouse all transform exteriors differently

How accurate are AI exterior design apps?

The best apps preserve your house's actual structure — roofline, windows, garage, driveway — and only change the surface materials and landscaping. Lower-quality apps sometimes add extra stories, change window counts, or generate a completely different building. Always compare the output to your actual house before using it for planning.

What is the cheapest exterior design app?

Remodel AI at $39.99/year ($3.33/month) offers unlimited exterior designs. Home AI offers 2 free daily designs with ads. DecAI has a one-time $49.99 lifetime purchase.
