Overview
KnowledgeGPT is a document-based question-answering system that allows users to upload their documents and receive accurate answers with instant citations from the source text. Built on Streamlit for the user interface and Langchain for LLM tooling, it provides a straightforward way to interact with your documents using natural language queries. The tool integrates with OpenAI's API to process documents and generate responses, making it particularly valuable for researchers, students, and professionals who need to quickly extract information from large document collections. With support for various document formats and the ability to provide specific citations for each answer, KnowledgeGPT bridges the gap between document storage and intelligent information retrieval. The system runs locally via Streamlit server, giving users control over their data while leveraging powerful language models. Its open-source nature under MIT license makes it accessible for both personal and commercial use, with active development and community contributions. The tool supports Docker deployment for easy setup and scaling, and offers customization options like adjustable upload file sizes. While currently focused on document-based Q&A, the roadmap includes ambitious features like OCR support for scanned documents, webpage integration, and local LLM support.
