About OP Vault ChatGPT

OP Vault ChatGPT is an open-source tool that gives ChatGPT long-term memory by using the OP Stack (OpenAI + Pinecone Vector Database). It allows users to upload their own custom knowledge base files—including PDF, TXT, and EPUB—via a React frontend, and then ask questions about the uploaded content. The backend is built with Go and leverages Pinecone for vector storage and OpenAI for understanding queries. Users receive answers along with the specific filename and section that informed the response, making it ideal for extracting knowledge from books, letters, and other human-readable documents. The tool can be self-hosted, giving full control over data and configuration.
