DiffusionBee

DiffusionBee is a free macOS desktop app for artists, creators, and beginners who want to generate and edit AI images locally using Stable Diffusion.

It includes a set of creation and editing tools designed for on-device workflows:

• Text to Image and Image to Image generation with advanced controls such as negative prompts and diffusion steps
• Generative Fill (inpainting) for adding or removing objects in selected regions
• Image Upscaler and Image Variants to enhance resolution and explore multiple outputs from a source image
• Extra modules such as Video Tools, Control Images, Illusion Generator, and the ability to train custom models on personal datasets

Pricing: Free.

What makes it notable is its 100% offline design, prompts, models, and generated images stay on the user’s device with no cloud dependency. It also provides public resources such as documentation, a video tour, and an active Discord community, and it has been referenced in multiple AI tool reviews and comparisons.
