ChatPDF

Upload a PDF and ask questions with page references, with no sign-up for the first files

ChatPDF is the simplest way to question a long PDF: upload the file, ask in any language and get an answer with a page reference. It works with contracts, manuals, reports and research papers, and lets you group several files in a folder and ask across all of them. It suits a quick first look at a document before it is worth setting up NotebookLM or Claude.

• Check answers about amounts and dates on the cited page, because the model rounds
