When not File size limits.
A web tool that lets users upload any PDF document and have a natural language conversation with its contents using AI. Users ask questions about the document and ChatPDF retrieves and synthesizes relevant passages to generate a direct answer with page references. It works for research papers, legal contracts, financial reports, textbooks, manuals, and any other document-based content. The tool handles documents up to several hundred pages and retains context across multiple questions in the same session, making it possible to explore a complex document through conversation rather than linear reading. A summary is auto-generated when a document is first uploaded. Free plan covers 2 PDFs per day up to 120 pages each; Pro is $5/month for more PDFs, larger files, and higher message limits. Popular with students reading academic papers, lawyers reviewing contracts, and analysts processing reports.
