What is ChatPDF?
ChatPDF is an AI document assistant that lets users ask questions about PDFs and receive answers based on their contents. It can summarize documents, explain specific passages, compare information, and provide citations that link responses back to the source material. The service is designed for academic papers, books, reports, contracts, manuals, presentations, and other text-heavy files.
Despite its name, ChatPDF supports more than PDF files. Users can also upload Word documents, PowerPoint presentations, Markdown files, and plain text files. Documents and questions can use different languages. ChatPDF is available through a web browser, with desktop and mobile apps also promoted on its site.
Key Features
- Document chat: Users can upload a supported file and ask questions about its content through a conversational interface.
- Summaries and analysis: ChatPDF can condense research papers, academic articles, reports, and other documents into key points.
- Source citations: Answers include references connected to the original document, helping users check the supporting text in a side-by-side view.
- Multi-file conversations: Registered users can organize files into folders and ask questions across several documents within one chat.
- Multilingual support: The tool accepts documents in different languages and can answer in the user's preferred language, including a language other than the source document's.
- Sharing and privacy controls: Documents remain private by default, while optional links allow users to share selected PDFs and revoke access later.
Use Cases
- Reviewing scientific papers and locating evidence for academic research.
