ResearchGPT

ResearchGPT is an open-source FastAPI application that lets users have a conversation with a research paper instead of reading it start to finish. Users provide a link to a PDF hosted online or upload their own file, and the app extracts the text, splits it into chunks, and generates embeddings that are stored locally in Redis. When a user asks a question, the system retrieves the most relevant passages and sends them to the OpenAI API to produce an answer, citing the specific page number the response was drawn from so the user can verify the source in the original document. The project is aimed at students, researchers, and anyone who needs to quickly extract information from dense academic PDFs without manually skimming every section. Running it requires cloning the GitHub repository, installing the Python dependencies, setting up a local Redis instance, and supplying a personal OpenAI API key, since the tool does not host its own service or handle billing for API usage. It is released under the MIT license, making it free to modify and redistribute. One important limitation: the repository was archived by its creator in November 2023 and is no longer actively maintained, so it may not work with current library versions without manual fixes; the creator points users toward a successor project instead.
