Lovable builds and edits full-stack web apps from natural language. Describe an app and Lovable creates a project, writes the TypeScript, Tailwind, and shadcn/ui code, and returns a live preview you can watch build. Follow-up messages refine the app, and you can inspect the generated code and diffs, add a PostgreSQL database and third-party connectors, manage reusable project knowledge and skills, and publish the finished app to a public URL.
