Upload a sketch, doodle or line art and describe the finished image — an architectural render, a product photo, a 3D toy or a coloured illustration. Your lines and proportions stay.
Quick answer
Updated
Kenerate's sketch to image AI turns a drawing into a finished image: upload your sketch, doodle or line art and describe the result — a photoreal render, a product photo, a 3D figure or a coloured illustration. Seedream 5.0 Pro (up to 2K, up to 10 reference images) kept the shapes most faithfully in our tests; Flux 2 Dev (free plan, up to 2048 px) is a quick way to start, and Z Image Base lets you set how much changes with a strength slider.

In depth
What works, what to avoid, and how to pick a model.
Reference-based models read your sketch as a guide for shape and composition, then draw a finished image from your description. Noise-based models like Z Image Base redraw the sketch itself, with strength deciding how far they move from it.
Architects turn concept sketches into client renders, product designers check colourways, illustrators colour line art, and parents turn children's drawings into toys — all from the same upload-and-describe flow.
We only publish real, verified reviews — never invented quotes. Send a line about your result (and whether we may quote you), and it will appear here.
