V0 is a generative user interface system powered by AI that generates copy-and-paste friendly React code based on Shadcn/UI Tailwind CSS. It uses AI models to generate code based on simple text prompts, giving users three choices of UI designs to choose from. Users can refine the generated UI by selecting individual parts and fine-tuning them further before copying and pasting the final product into their projects. V0 is trained using custom code mixed with open-source synthetic datasets, but no customer data or code will be used for training or improving its models during beta testing
