Invoke

Invoke is an open-source, professional-grade image generation platform that gives artists and developers full control over the creative process. Unlike typical AI image tools, Invoke provides a layer-based editing environment similar to Photoshop, allowing users to compose, refine, and iterate on generated images with precision. Its core capabilities include regional prompting, which lets you apply different prompts to specific areas of an image, and full support for custom models, enabling you to work with your own fine-tuned or community models. The platform can be self-hosted for maximum privacy and customization, or accessed via a cloud service for convenience. Invoke is designed for professional artists, designers, and developers who need a reliable, controllable, and extensible tool for production workflows, whether for concept art, marketing materials, or experimental generative art.
