ChatPDF

What it does

ChatPDF lets you ask questions about documents in plain language and get written answers. It accepts PDF, Word, PowerPoint, Markdown, and text files, and you can also paste text or links to start a chat. Answers include built-in citations that point back to the source passage, so claims can be checked directly.

A typical session starts with dropping in a file, then asking for a summary, a translation, or a specific fact. You can create a folder and add several files to compare content in one conversation. Documents can be in any language, and you can ask questions in a different language from the file. A side-by-side view keeps the chat and the document open together, with clickable citations that scroll to the matching passage.

The product is aimed at researchers, students, and professionals working through papers, study materials, contracts, financial reports, and manuals. A free plan allows two document analyses per day and requires no account to start, while a free account adds saved history and multi-document chats. Queries are routed between GPT-4o and GPT-4o-mini, so verifying important answers against the cited passages is sensible.
