Krea 2 Sketch to Render
Turn hand sketches into photoreal architectural renders with Krea 2 in RenderChat. Upload your hand sketch, describe what you want, and refine the render in chat.
Pro plan2KOne request per render
Drag to compare the hand sketch with the Krea 2 render. Input is an AI-generated example. Krea uses the input as a style reference. The result can retain the input's model-like finish and change its geometry or camera.
Before you start
Prepare your hand sketch
A sketch carries the idea long before there is a model. Photograph it, tell RenderChat what the lines mean — glass, timber, trees, the time of day — and get a rendered version you can show, discuss and redraw over.
Strengthen faint lines
If the pencil is light, raise the contrast so the important lines read clearly.
Explain the lines
In your brief, say what the ambiguous strokes are: which surfaces are glass, which shapes are trees, where the entrance is.

Open RenderChat with Krea 2
The start button on this page opens a new chat with Krea 2 selected. You can also pick it from the model menu in the composer.
Upload and write the brief
Attach the image and say what must stay, then the materials, light, setting and people. Start from an example brief below.
Refine in chat
Ask for changes in follow-up messages. Each Krea 2 request is sent fresh from your latest image, so repeat the constraints that matter.

Download the image at the resolution you chose (2K).
Example briefs
Sketch to render briefs to start from
Copy a brief, paste it into RenderChat with your hand sketch, and change the materials and mood to match your project.
Turn this hand sketch into a photoreal render. Follow the perspective and proportions of the drawing. White brick walls, large timber-framed windows, a pitched zinc roof, a gravel path and wild grasses, soft morning light.
Render this sketch as a soft, painterly architectural visualization. Keep the linework visible, add watercolor washes for materials and sky, warm afternoon light.
Krea 2 in RenderChat
Working with Krea 2
Krea 2 Large. RenderChat sends each render as one complete request and supports style references, so a studio look can travel with the brief.
- Attach one or two past renders as style references to keep a series consistent.
- Uploaded images guide style; this endpoint does not provide a separate geometry-preserving edit control.
Quality check
What to check before you share it
- Lines the AI read differently from your intent — correct them by name in the next message.
- Proportions: loose sketches can stretch or compress in the render.
- Window and door positions on the main facade.

FAQ
Krea 2 Sketch to render questions
Is Krea 2 available on the free plan?
Krea 2 is available on the Pro plan. On the Free plan you can use GPT Image 2.5 and Nano Banana 2.1.
What resolution does Krea 2 render at?
Krea 2 renders at 2K in RenderChat, with auto + 7 fixed ratios.
Can I keep refining a Krea 2 result in chat?
Yes. Each follow-up is sent to Krea 2 as a fresh request built from your latest image and instructions, so restate the constraints that matter.
How do I select Krea 2 in RenderChat?
Use the start button on this page — it opens a new chat with Krea 2 selected — or choose it from the model menu in the chat composer.
How rough can the sketch be?
Rough is fine if the perspective is legible. The looser the drawing, the more the AI fills in, so describe materials and key elements in words.
Can I keep the hand-drawn character?
Yes. Ask for a painterly or watercolor rendering that keeps the linework instead of a photoreal image.
