ASTROCODES8/ResearchAI ? reverse-engineered prompt

Build me a full research paper assistant where people can upload PDF papers, get an automatic summary, and then ask natural language questions about the papers later.

I want a clean modern web app with signup, login, saved session, upload history, query history, and a page to view each paper’s details. After a PDF is uploaded, the app should extract the title, authors, date, summary, and key concepts, then let users ask questions and get answers with citations and source snippets. It should also show an interactive knowledge graph so users can explore how concepts and entities connect.

Please wire up the frontend and backend so the whole flow works end to end, including storing paper data, search results, and user history. Use the existing API and data flow in the repo, and look up current docs online if you need to. Make it polished, responsive, and good looking in dark mode too.
