About ChatPDF

ChatPDF lets you upload any PDF and ask questions about it in natural language. Originally built for students to analyze research papers and textbooks, it has grown to serve professionals reading legal contracts, financial reports, and technical documentation. Simply upload a PDF up to 120MB, and ChatPDF processes it into a conversational AI interface — ask 'what are the main findings?', 'summarize page 15-20', or 'what does the contract say about liability?' It supports 50+ languages and works on any device.
