labring/FastGPT ? reverse-engineered prompt

Build me a web app like FastGPT, where people can create AI assistants that answer questions from their own documents and knowledge bases.

I want a clean dashboard where users can upload files, add content from URLs or text, organize knowledge bases, and then use that content in a chat experience with citations. It should also let users visually build simple AI workflows, chain steps together, and test or debug how the agent responds. Include a way to share a chat without login, embed it in another site, and view conversation history and usage logs.

Make it feel like a real product, not just a demo, with a polished admin area, good empty states, and sensible defaults so it works right away. If you need anything unclear, look up the current docs online first.
