ashisherikilla/DocIntel ? reverse-engineered prompt

Build me a web app that lets me upload PDF files, turn them into a searchable knowledge base, and then ask questions in plain English about what’s inside them.

I want the app to answer only from the uploaded documents, and show where each answer came from with the document name, page number, and the exact text chunk it used. If it can’t find a solid answer, it should say that clearly instead of guessing.

It should also let me see my uploaded documents in a simple library, view basic stats, delete a document, and upload it again if needed. The UI should feel clean and modern, work well on desktop and mobile, and show loading, processing, empty, and error states nicely.

Please build the full thing with a React frontend and a FastAPI backend, using Gemini for embeddings and answers, plus a vector database for semantic search. If you need current docs or setup details, look them up online and make it work end to end.
