Upload your own documents and ask questions that only draw on those sources.

ChatPDF
Upload a PDF and ask it questions, with answers that point to the page they came from.
Quick take
- Drop in a PDF and start asking questions. No account needed for the basics.
- Answers come with citations that jump to the right page, so you can check them.
- Free covers 2 documents a day. Plus removes the limits.
- NotebookLM does the same free with more features, so ChatPDF wins mainly on speed and simplicity.
What is ChatPDF?
ChatPDF does one thing simply: you upload a PDF and ask it questions. It answers in a chat next to the document, with citations that jump to the page the answer came from. It also handles Word, PowerPoint, Markdown and text files, works in any language, and you can put several files in a folder and ask questions across all of them.
You don't need an account to start, which makes it handy for a quick question about a manual, a report or a contract. A free account saves your chat history and adds multi-file chats, and you can share a document chat with someone by link. It also has a desktop app and an API, plus newer extras like summaries, flashcards and slides.
The catch: the free plan is limited to 2 documents a day, and Google's NotebookLM does the same job free with more features, such as audio summaries. Claude and ChatGPT can also read PDFs if you already pay for one. Pick ChatPDF for speed when you don't want to sign in to anything.
