What is it?

Invoke is a creative engine for generating visual media with AI image models. It runs a locally hosted web server and React-based UI, so users work in a browser against models installed on their own machine. The project is distributed through a launcher and supports Windows, macOS, and Linux.

The Unified Canvas supports text-to-image, image-to-image, in-painting, and out-painting, with brush tools for refining existing pictures or sketches. A node-based workflow editor lets users build and share custom generation pipelines, and a gallery with boards stores outputs with embedded metadata so prompts and settings can be recalled.

The project supports a long list of model families, including SD 1.5, SDXL, SD 3.5, and several Flux variants, along with embedding and model managers, upscaling tools, and SAM/SAM2 segmentation. Some models are available only through external APIs.
