ChatPDF is a web application that utilizes powerful AI to enable users to chat with and extract information from various types of documents, including PDF, TXT, CSV, MD, DOCX, PPT, EXCEL, JPG, JPEG, PNG, JSON, and web pages.

The tool is designed to provide a chat-like experience and can be used to communicate with documentation in different formats.

It offers several features such as chatting with documents, web pages, Twitter, Slack, Github, Reddit, and Discord.

ChatPDF utilizes Azure OpenAI Service to create embedding vectors from documents and retrieve the most relevant document to answer user questions.

It employs AI models like text-embedding-ada-002, GPT-3, and ChatGPT to extract matching answers for user queries.

The tool also supports knowledge base management, including knowledge base indexing, sandboxing, data extraction, and document summarization.

The application uses an instruction-based model (similar to text-davinci-003) and chat-based deployment (text-embedding-ada-002, GPT-3, and gpt-35-turbo AI models) for Q&A and chat experiences.

It integrates with users' own online knowledge bases, allowing them to chat with and extract information from PDFs, TXT, JPEG, JPG, and PNG files within their knowledge base.
