MuninderCoder/VaultIQ ? reverse-engineered prompt

Build me a secure enterprise knowledge platform where people can sign up and log in, upload documents like PDF, Word, text, and markdown, then search across them and chat with an AI assistant that answers using only the uploaded content and shows source citations. I want a clean dashboard where users can see their documents, upload status, file details, and basic stats, plus pages for search, chat, settings, and login. It should support multiple organizations, so users can switch workspaces, only see documents they have access to, and have role based permissions like owner, admin, editor, and viewer. Please include document processing in the background, text extraction, semantic search, and a conversation history that saves chats. Also make it production ready with JWT auth, MongoDB, file size limits, safe file storage, audit logs, and a nice modern React interface. If you need to, look up current docs online for any libraries you use.
