Chat with PDF
Chat with any PDF and get answers with citations
Upload a PDF and ask questions in plain language. Doxy reads your document and answers with citations, so you can find and verify exactly what you need.
Upload a PDF and just ask
Drop in a PDF — a contract, research paper, manual, textbook or report — and Doxy converts it to clean text and reads the whole thing. Ask questions in plain language and get answers in seconds, without scrolling through hundreds of pages or using Ctrl+F to guess at keywords.
Every answer cites the source
Unlike a general chatbot, Doxy answers only from the PDF you give it and shows the exact passages it used. That means grounded, verifiable responses you can trust — you can click straight through to the source to double-check every claim.
What you can ask
- “Summarize this PDF in five bullet points.”
- “What does section 4 say about cancellation?”
- “List every date and deadline mentioned.”
- “Explain this concept like I'm new to it.”
- “Compare the conclusions of these two papers.”
Beyond PDFs
Doxyisn't limited to PDFs. Add Word, PowerPoint and Excel files, images, audio, HTML, CSV, ZIP and EPUB, or paste a web link or YouTube URL, then chat across all your documents at once. It's great for document Q&A, works as an AI research assistant and a great NotebookLM alternative.
Guides: chat with your PDFs
Want to go deeper before you upload your first file? Our guide How to Chat With a PDF Using AI walks through the whole workflow step by step, from creating a project to reading the citations under each answer. If your problem is length rather than complexity, How to Summarize Long PDFs With AI shows how to condense a 100-page report into key points you can question further. And if you're curious why the answers stay grounded in your file instead of being made up, What Is RAG? explains retrieval-augmented generation — the technique behind every cited answer — in plain language.
Frequently asked questions
How do I chat with a PDF?+
Create a project, upload your PDF, and type a question. Doxy reads the document and answers with citations pointing back to the exact source passages.
Is there a free way to chat with a PDF?+
Yes. Doxy has a free plan that lets you upload a few documents and ask a monthly allowance of questions. Pro and Business plans raise the upload and question limits.
Is my PDF private?+
Your documents are scoped to your account and to the project they live in — context never leaks between projects or users. See the Privacy Policy for details on storage and processing.
How big a PDF can I upload?+
The free plan accepts files up to 10 MB, Pro up to 50 MB and Business up to 200 MB per file. Larger documents are split into chunks so you can still ask about any part of them.
Can I turn a PDF into a quiz or practice exercises?+
Yes. On the Pro and Business plans, Doxy can generate a multiple-choice quiz or open-ended practice exercises from the PDFs you select. It's a quick way to test yourself on a textbook chapter or paper after you've read the summary.
Can I chat with a PDF and other sources together?+
Yes. Add PDFs, Office files, images, audio, web links or YouTube videos to the same project and ask one question across all of them. Doxy pulls the most relevant passages from whichever source holds the answer.
