Manarfekih/Saas_Platform ? reverse-engineered prompt

Build me a full stack SaaS app where users can sign up, log in, upload documents, and then chat with them like a smart assistant. I want it to handle common file types like PDFs, images, Word files, text, and slides, pull the text out automatically, organize it into searchable pieces, and let users ask questions in natural language and get answers based on their own files.

It should also be able to summarize documents, classify them, and show document status as it processes each upload. Each user should only see their own documents, with protected login and basic account management. Please include a clean web interface for uploading, browsing, and chatting, plus a solid backend that stores documents and searchable embeddings in a database so retrieval feels fast and accurate.

If anything is unclear, make sensible choices and look up current docs online if you need to.
