Question: Can you recommend a tool that uses Stable Diffusion to generate images with various models and extensions?

For creating images with multiple models and extensions using Stable Diffusion, ThinkDiffusion is a great option. This cloud-based service lets you generate creative content without writing any code or worrying about setup. It has multiple interfaces for different skill levels, 200GB of persistent storage, and a variety of preinstalled extensions like Wav2Lip and Loopback Wave. With support for advanced techniques like lip syncing and multi-stage morphing clips, it's geared for creatives, agencies and businesses.

Another option is GRAVITI Diffus, a web interface that makes Stable Diffusion easier to use for digital art creation. It includes AUTOMATIC1111/Stable Diffusion WebUI and options like ControlNet for conditioning input images and prompts, as well as One Click Face Swapper. The service offers free and paid accounts, including an API for developers, so it's good for both casual and serious users.

If you prefer an open-source option, Picture it is an AI art editor that offers fine-tuning controls and prompt suggestions to optimize image quality. It also includes guided drawing, outpainting and inpainting tools, so it's a good option for digital artists and designers. The community-run project is actively maintained with new features and contributions.
