NMKD Stable Diffusion is a free AI image generation tool that supports text-to-image, image-to-image, instruction-based editing, custom models, and text masking, and provides a convenient installation method.

Gradio is a lightweight Python library for quickly creating interactive web interfaces for machine learning models. Developers can use it to showcase, test, and share models, and it can also be embedded in Notebooks.

OpinioAI is an AI-powered research platform that can help researchers find insights, data, and opinions in a scalable way. They use language models instead of traditional survey and polling methods. They also offer a tool to build an AI version of a buyer persona. DeepOpinion is another AI automation tool that can be used to create custom models for intelligent text and document processing.

Lobe is a free and easy-to-use machine learning modeling tool that lets users train custom models by providing example data, making it suitable for people who want to quickly build intelligent features without dealing with complex processes.

Civitai (C-site) is an online platform and community focused on the creation and sharing of artificial intelligence image drawing and artistic works. Users can upload and share custom models trained on their own data (mainly based on Stable Diffusion), and can also browse and download models created by other users, then use these models together with AI image generation software to create unique artworks.
