Convert sketches to photorealistic renders

Overview

Sketch AI transforms hand-drawn sketches, line drawings, and rough floor plans into photorealistic renders. Upload your sketch and the AI generates a realistic interpretation. You can specify a design style and provide a reference image for style matching. Perfect for architects and designers who want to quickly visualize rough concepts.

Tips

1Works with pencil sketches, pen drawings, architectural line drawings, and even rough digital sketches.
2Include a "prompt" to help the AI understand what the sketch represents.
3Use "style_transfer" with a reference photo to match a specific visual style from a magazine or portfolio.
4Clean, high-contrast sketches on white backgrounds produce the best results.
