About InvokeAI

InvokeAI, also called Invoke, is a creative engine for Stable Diffusion models aimed at professionals, artists and enthusiasts who want to generate and refine visual media. It runs a locally hosted web server with a React interface, and the project says it also serves as the base for several commercial products. The code is Apache-2.0 licensed, which the README describes as commercially friendly.

You download and install it on compatible hardware using the Launcher, then generate and iterate on images and build workflows. Features include a Unified Canvas for editing, and repository topics list text-to-image, image-to-image, inpainting and outpainting. It runs on Windows, macOS and Linux. Documentation covers installation, updates and tutorials, and the FAQ and Discord server handle common installation problems. Because generation runs locally, results depend on your GPU and the models you load.
