Carve is the Krea alternative for fast, photorealistic rendering
Krea is a general AI creative suite strong at upscaling and video, often used to enhance renders. Carve is a purpose-built AI archviz tool with CAD input, geometry control, and staging. Here is how they compare.
CarveCarve vs Krea: at a glance
Krea is a broad, low-cost creative platform: image generation, a real-time canvas, video, and large upscaling up to very high resolutions. For architects, its real value is enhancing and upscaling existing renders, not running an end-to-end archviz workflow.
Carve is built specifically for architecture: render from sketches, CAD exports, and photos with geometry preserved, stage rooms, and produce short video.
Think of Krea as a general tool you bolt on for upscaling and video, and Carve as the archviz workflow itself.

Credit where credit is due
Krea is an excellent general AI suite, especially for upscaling and video, at a very friendly price. Many architects use it happily to push renders to high resolution.
This page isn't here to argue otherwise. Krea is horizontal, though, with no CAD input, no architecture sketch-to-render workflow, and no geometry lock for buildings. The comparison is about a purpose-built archviz tool versus a general one.
3 reasons to pick Carve over Krea
The three biggest reasons teams switch from Krea to Carve.
Built for architecture
Carve renders from CAD and sketches with geometry preserved. Krea is a general image and video tool.
CAD input and staging
Carve ingests CAD exports and stages rooms. Krea offers neither.
End-to-end workflow
Carve takes you from a design input to a client-ready render. Krea mainly enhances images you already have.
A fundamentally different rendering experience
Krea generates and enhances images and video across any subject. Carve is built for architecture: it ingests CAD exports and sketches, keeps your geometry intact, stages rooms, and renders interiors and exteriors. Krea is a general creative tool; Carve is an end-to-end archviz workflow.
Why modern firms choose Carve over Krea
Photoreal results in under a minute
Carve's AI pipeline returns a finished, photoreal image in under a minute, right in the browser. There's no scene to assemble and no local GPU to wait on.
Render straight from a sketch or CAD
Upload a hand sketch, a CAD export, or a SketchUp model and Carve renders directly from it. Depth and edge routing keeps the geometry true to your design.
Virtual staging from a single photo
Furnish and restyle an empty room from one photograph. No 3D model and no manual set dressing, just a staged, listing-ready image.
No installs, works on any machine
Carve runs entirely in the cloud, so there's nothing to download and no GPU to buy. Log in from any browser on Mac, Windows, or Chromebook and render from exports made in Revit, SketchUp, Rhino, and more.
A fraction of the cost
Carve starts at $29 a month with no annual contract and no hardware to buy. You get photoreal, client-ready renders for a fraction of what a traditional rendering studio or a desktop suite costs.

Who is Krea best for?
Krea is the better fit when you want general image and video AI plus heavy upscaling. Krea is the better choice if you:
- Upscale and enhance existing renders to very high resolution
- Generate general images and video beyond architecture
- Want a very low price and broad creative tools
- Don't need CAD input, sketch-to-render, or staging
Who is Carve best for?
Carve is the stronger choice when speed, cost, and accessibility matter most. Consider Carve if you:
- Don't have a dedicated rendering team
- Work on tight client deadlines
- Need concept and marketing visuals fast
- Want to work from a Mac, Windows, or a browser
- Care about the cost per image
Which one should you pick?
