How it works

1 · Upload your sketch

Any drawing works — pencil on paper, digital line art, or even a quick napkin sketch scanned with your phone.

2 · Describe the target style

Tell the model what you want: material, lighting, artistic style, and level of detail. The more specific, the closer the result to your vision.

3 · Generate the render

Mintdreamer processes your sketch and prompt together, producing a render that respects your original composition.

4 · Refine or iterate

Not quite right? Adjust the prompt or upload a cleaned-up version of your sketch and generate again. Each run takes seconds.

What it costs

Flux Kontext Pro starts at 8 credits per output at default settings. Check your settings and total in Studio before running.

Made for

Architecture and interior design

Architects can convert hand-drawn floor plans and facade sketches into client-ready renders without waiting for a 3D model, compressing concept approval cycles significantly.

Product and industrial design

Product designers can turn ideation sketches into photorealistic studio shots to share with stakeholders before committing to prototypes.

Character and concept artists

Game and animation artists can explore character designs by rendering multiple costume or style variations from a single pose sketch.

Illustrators and graphic designers

Illustrators can use their rough thumbnails as a starting point and let the AI handle rendering heavy lifting, freeing time for creative direction.

Students and hobbyists

Anyone learning to draw can see their ideas rendered at a professional level, which is motivating and useful for portfolio building.

Questions

Does my sketch need to be clean or detailed?+
No. The AI works with rough sketches too. Cleaner line art gives more predictable results, but loose gesture drawings also produce interesting renders.
Can I control the level of realism in the output?+
Yes. Prompt phrases like 'photorealistic', 'watercolor', 'cel-shaded', or 'technical illustration' steer the rendering style effectively.
What file formats are accepted for the sketch upload?+
JPG, PNG, and WebP are supported. Black-and-white line art on a white background typically gives the clearest results.
Will the AI change my composition?+
The flux-kontext-pro model is specifically trained to respect input structure, so your layout and proportions are preserved while rendering adds detail.
Can architects use this for client presentations?+
Yes. Many architects use sketch-to-render tools in early design phases to communicate concepts before 3D modeling begins.
