pdfGPT is a retrieval augmented generation application and chatbot designed to analyze PDF documents. It functions as a document analyzer and vector search interface, using large language models to answer questions grounded in the content of uploaded files. The system implements a pipeline that extracts text from PDFs, splits content into overlapping segments, and uses vector-based semantic search to retrieve relevant context. This process allows the application to provide responses with verifiable source citations, including page number references to the original document. The project also

BookStack is a self-hosted knowledge base platform designed for organizing, storing, and managing structured documentation. It utilizes a hierarchical content model that arranges information into nested trees of books, chapters, and pages, supported by a dedicated search index for rapid retrieval across the entire knowledge base. The platform distinguishes itself through deep integration with enterprise identity providers, allowing organizations to centralize authentication and access control via LDAP, SAML, or OIDC. It provides extensive administrative control over the content lifecycle, inc

This project is a self-hosted AI frontend and web-based chat interface designed to interact with large language model APIs. It functions as an API-based chat client and dashboard that enables users to send prompts and receive responses from generative AI models. The application serves as a self-hosted AI gateway, providing API key proxying to connect official model keys to a web interface. It includes security and traffic controls, such as interface access restrictions via a shared secret key and request volume limiting to prevent service abuse. The system covers conversation data management

PrivateGPT is a private AI document assistant and local knowledge base manager designed for querying private files and documents using retrieval-augmented generation. It functions as a local language model application and API gateway, allowing users to obtain cited answers from unstructured data without sending information to external servers. The system differentiates itself by acting as a tool integrator that connects language models to external functions, including web search, tabular data analysis, and custom action extensions. It provides a standardized API layer that allows local infere
