Our Verdict

SoftGist Rating


In our Scribble Diffusion review, we were impressed by its simple and intuitive user interface. It’s a free and open-source project that turns sketches into refined images using AI. Inspired by Stable Diffusion, users can enter text prompts to describe their desired image output, like specific colors, paint types, and other elements.

It's an excellent tool for independent artists and digital art hobbyists since it allows quick and unlimited image generation, enabling them to experiment efficiently with various scribbles and prompts.

However, one of the tool’s downsides is its lack of photo editing and customization features. It produces average-quality images, which makes it less ideal for professional use. Also, non-artistic users might need time to generate their desired image since the tool requires an accurately drawn sketch to work effectively.

Is Scribble Diffusion Right for You?

We recommend Scribble Diffusion if:

  • You want to create fast generative art using unique scribbles
  • You want to experiment with various scribble styles and text prompts
  • You’re a digital artist looking to discover new art inspirations and styles using scribbles

Scribble Diffusion is not ideal for users who:

  • You want more control over the image creation process
  • You’re a non-artistic user who struggles with drawing accurate sketches
  • You want a unique AI-generated image with personalized filters and effects

Pros & Cons of Scribble Diffusion


Free and open-source software

Scribble Diffusion is a free and open-source project by Replicate, a cloud-based platform that hosts machine learning models. Users can access the tool through its official site.


The tool has a simple interface where users can draw scribbles and input a brief description of the output image. After a few seconds, the tool produces a realistic photo that mimics the scribble input.

Images can be customized using text prompts

Besides inputting accurate scribbles, users can customize the output image by entering detailed text prompts, which include their desired painting style, color themes, etc.

Unlimited image generation

As a free tool, Scribble Diffusion allows unlimited image generation, making it an ideal digital canvas for users experimenting with different scribble and art ideas.


Generated images lack originality

Since the tool is trained on existing images online, it provides fewer original images than human-made art.

Relies on accurate scribble inputs

Users ideally need to draw an accurate scribble to get their desired result, meaning non-artistic users could struggle using the tool.

Lacks photo editing Features

Scribble Diffusion lacks photo editing features (e.g., resizing, color and contrast adjustment, etc.), limiting the amount of customizations a user can make.

What Sets Scribble Diffusion Apart

Unlike other AI image-generating tools that use diffusion techniques, Scribble Diffusion has various input conditions, such as detecting key points or edges in the sketch to provide its AI with a deeper understanding of the elements and composition included in the sketch. It allows for more accurate image generation outputs. The app is also free, user-friendly, and open-source.

Key Features

Scribble Diffusion has a straightforward and easy-to-use interface, where you’ll be required to draw a raw scribble of any object, person, place, or animal you want the tool to create. It has a text prompt field where you can input a description of the image. You can enter specific elements, like colors, type of painting, or other objects you want to include in the photo:

For instance, we’ll use a cat, a default scribble from the site. However, we’ll input a more specific prompt, such as: “oil painting of a cat colored orange and white”. Here is its initial output:

We’ll ask the tool to regenerate the image, which produces the following image:

While it initially generated a literal image of an orange cat beside an orange fruit, the tool constantly produced a realistic image.

Another example that we can try is a scribble of two mountains with a sun behind them. We’ll enter the prompt: “abstract painting of a sun setting behind the mountains”. Here’s what it generated initially:

We’ll ask the tool to regenerate the scribble with the same prompt. Here’s the result:

It generated a more refined image the second time, depicting the scribble accurately.

Overall, we enjoyed generating images from our input scribbles and text prompts. However, it lacks photo customization features, which are needed for resizing the photo, adjusting its contrast, and other editing tasks.


Scribble Diffusion is a free and open-source software that AI image generator hobbyists and digital artists can use for art inspiration. Users can access it via the tool’s official site.

Final Thoughts on Scribble Diffusion

Scribble Diffusion is an interactive AI image generator tool that enables users to create generative art using a scribble and a brief image description. We liked its scribble input, which allows digital artists to use the tool as a canvas for art ideas. It also offers unlimited image generation, making it an excellent platform for generative art hobbyists experimenting with various scribble styles.

We gave the tool an overall rating of 4.2/5, mainly due to its ease of use and speed in creating output images. However, the tool may generate fewer unique images since it's trained on existing images online. It also lacks photo editing features, which is a downside for users wanting to customize output photos.

We highly recommend this tool for digital artists and generative art hobbyists who desire to create art from scribbles.

Got Questions?

How is Scribble Diffusion used in digital art?

Scribble Diffusion can be used for precise drawing inspirations since it considers a scribble of the user’s desired image and a text prompt. The tool is free, easy-to-use, and AI-powered, allowing for quick and unlimited photo-realistic image generation. Users can explore various scribble ideas and styles, undo mistakes in their work, and generate an image until they get their desired result.

Is Scribble Diffusion completely free?

Yes. Scribble Diffusion is a free, generative art tool you can use on their official website.

What are alternatives to Scribble Diffusion?

Some popular Scribble Diffusion alternatives are Playground AI, Stable Diffusion, and AI Picasso. These freemium tools use powerful AI algorithms similar to Scribble Diffusion but produce more high-quality and customizable images.

What are the limitations of Scribble Diffusion?

While Scribble Diffusion is a free, interactive AI image generator with an easy-to-use interface, it has a few limitations, which include limited image customization options and mediocre image quality on outputs. It also relies heavily on the accuracy of your scribble input, which means that non-artistic users can take time to achieve an accurate result.

Is Scribble Diffusion suitable for beginners?
