Sketch to Image AI with Controlnet Scribble

Seedance 2.5 IS HERE · Nano Banana 2 & GPT Image 2.5 UNLIMITED UNTIL October 10Upgrade

Overview

Controlnet Scribble is a sketch-to-image AI that converts rough line drawings into detailed, finished visuals using a text prompt to fill in style and content. On Picasso IA, it solves a specific problem: you have a clear spatial idea in your head but lack the vocabulary to describe it precisely in words. A scribbled outline of a room, a character, or a landscape gives the model a concrete spatial framework to work from. The result is an image that actually matches what you had in mind, not just a generic interpretation of a written description.

How It Works

Upload your sketch or scribbled drawing as the input image.
Write a text prompt describing the subject, style, lighting, or mood you want in the final image.
Optionally add a negative prompt to exclude unwanted elements like blurriness or extra limbs.
Set the fidelity scale and number of steps, then choose how many variations to generate.
Hit generate and receive one or four images that follow the structure of your sketch.

Frequently Asked Questions

Do I need programming skills or technical knowledge to use this? No, just open Controlnet Scribble on Picasso IA, adjust the settings you want, and hit generate.

Is it free to try? Yes, you can run the model on Picasso IA without paying anything upfront. Check the current credit policy on the platform for details on free usage limits.

How long does it take to get results? A single 512-pixel image typically processes in 15 to 30 seconds depending on the number of steps you set. Generating four samples at once takes proportionally longer.

What output formats are supported? The model returns standard image files you can download directly. The resolution options are 256, 512, and 768 pixels, suitable for digital use, presentations, and rapid prototyping.

Can I customize the output quality or style? Yes. The fidelity scale controls how closely the output follows your sketch lines. The number of steps affects sharpness and detail. Your text prompt controls the visual style, and the negative prompt removes elements you do not want to see.

What if my sketch is very rough or messy? Controlnet Scribble is specifically designed for rough scribbles, not clean technical drawings. A simple outline with basic shapes is enough for the model to work from. The text prompt does most of the heavy lifting for style and subject matter.

Where can I use the outputs? The images are yours to download and use however you need. They work for concept presentations, mood boards, social content, or as a starting point for further editing in other tools.

Features

Everything this model can do for you

Sketch-based input

Use any rough line drawing as the spatial input instead of relying on written descriptions alone.

Text prompt control

Combine your sketch with a written description to set the style, mood, and subject matter of the output.

Fidelity control

Adjust how closely the output follows your sketch lines, from loose interpretation to strict line adherence.

Multi-sample output

Generate up to four image variations from one sketch in a single run to compare results.

Negative prompt support

Specify what to exclude from the output to keep results clean and on target.

Resolution options

Choose 256, 512, or 768-pixel output to match your project's quality and speed requirements.

Seed control

Reuse a seed value to reproduce a specific result or iterate from a known starting point.

Fine-tune with quality and detail prompts

Use Cases

Convert a hand-drawn character outline into a finished illustration by adding a text description of the style and colors you want
