Two example prompts sit above the box. ### From doodle to print Finish the piece here, then double its size with the Upscaler for a print-ready file. ### Model choice Kontext is fast and faithful to the lines; Nano Banana follows a long description of the finish more closely. ## Every image model in one place Pick any of these from the Model menu above; the price is shown before you generate.

Faint lines give the model room to invent shapes you did not draw. ### Say what has to stay Add “keep every element and the exact layout” when the drawing is precise. Leave it out when you want the model to take liberties. ### Upscale for print The finished piece comes back around 1K. Double it before printing.

No. It keeps the layout, proportions and every element; only the rendering changes. ### ### What sketch quality do I need? Anything from a rough doodle to a detailed drawing. Higher contrast lines give more faithful results. ### ### Can I keep it black and white? Yes, ask for "finished in black ink only" or "graphite shading, no color". ### ### Is it big enough to print? Run the result through the Image Upscaler for twice the pixels; two passes give four times. ### ### What happens if a generation fails? You are only charged when an image comes back. If the model fails or times out, nothing is deducted and you can simply run it again. ### ### Can I use the results commercially? You keep ownership of what you upload and what you generate, on every plan; see the Terms of Service. Free downloads carry a small watermark, paid plans download without one. ## Finish the drawing Upload a sketch at the top of the page and describe the medium.
