Prompt-based AI inpainting
Select an area of an image and describe the desired change with a prompt, producing a generated edit for that region.
Scumble
Freemium
Free, open-source desktop image editor for AI-assisted inpainting with layers and PSD export.
What is Scumble?
Scumble is a free, open-source desktop image editor focused on AI inpainting. Its central workflow is to select an area, enter a prompt, and generate a colour-matched layer for the edit. The project combines generative image editing with a layered document workflow and supports PSD export for continued work in compatible software.
The repository lists FLUX 3 Image, FLUX.2, GPT Image, Nano Banana, Seedream, and Qwen as model options. These can be used through an API key or through the user’s own ComfyUI setup. Scumble also advertises MCP support, although the available source does not describe the full command set or integration procedure.
What can Scumble do?
Colour-matched layers
The project is designed to place generated inpainting results as colour-matched layers, supporting further adjustment within the document.
Multiple model options
The repository names FLUX 3 Image, FLUX.2, GPT Image, Nano Banana, Seedream, and Qwen as supported model options.
API key or ComfyUI workflows
Connect to supported providers with an API key or use your own ComfyUI setup as the image-generation backend.
Layered and PSD-based editing
Work with layers in the editor and export documents in PSD format for continued editing in compatible image applications.
MCP support
Scumble includes MCP support, providing a route for use with compatible Model Context Protocol tooling; detailed capabilities are not specified in the available source.
Use Cases
“Targeted image corrections”
Select an unwanted or incomplete area, describe the replacement, and use inpainting to make a localized change without rebuilding the whole image.
“Layered generative exploration”
Try alternate AI edits while keeping generated results in a layer-oriented document workflow, making it easier to compare or refine variations.
“ComfyUI-based image work”
Use an existing ComfyUI setup as the generation backend when a user prefers to work with their own ComfyUI environment rather than only an API-key connection.
“PSD handoff”
Export layered work as PSD when the image needs to move into another compatible editor for additional compositing or finishing.
