ChatPDF

What is ChatPDF?

ChatPDF lets you chat with documents the way you would with a general AI assistant. Drop in a PDF, Word file, PowerPoint, Markdown or text file, ask a question, and the answer comes back with clickable citations that scroll the document to the passage it came from. The chat and the file stay side by side, so checking a claim takes one click. You can group files into folders and ask questions that span several documents, upload in one language and ask in another, and share a read-only link with someone who has no account. Students use it for study and homework, researchers for papers, and professionals for contracts, reports and manuals. The site also has an academic search tool, an AI Writer, a YouTube chat and desktop and mobile apps. The free plan analyzes 2 documents a day, and ChatPDF Plus lifts that to unlimited documents, though the Plus price is not shown on its public pages, so check ChatPDF for current pricing.
