About researchgpt
ResearchGPT is an open-source, LLM-based research assistant that enables users to have a conversation with a research paper in PDF format. Built as a FastAPI application, it allows users to either provide a link to a PDF hosted online or upload their own PDF. The tool extracts text from the PDF, creates embeddings from that text, and uses the OpenAI API to generate responses to user questions. It also returns the source text and page number used to generate each response. The project is no longer actively maintained; its creator notes that a more advanced version is available at chat.portal.so and will be open-sourced soon. ResearchGPT requires a local Redis instance for storing embeddings and an OpenAI API key for operation.
