What is Alpaca?

Alpaca is a Photoshop plugin that integrates Stable Diffusion directly into Adobe's design software. It allows designers and artists to generate, edit, and manipulate images without leaving Photoshop, using text prompts to create new content or modify existing work. The plugin bridges the gap between traditional image editing and generative AI, making it useful for professionals who already work within Adobe's ecosystem and want to add AI capabilities to their workflow.
