Summarize PDF FAQ
Is Summarize PDF free?
Yes. A summary uses one of your 3 free advanced uses a day, or two with the Detailed style, and each follow-up question uses one more. Free works with PDFs up to 15 pages with Fast and 10 pages with Detailed. There are no ads on the page, so you can read in peace.
Is my document private when I summarize it?
Your PDF text is used only to create your summary and answer your questions. The text is read from the file in your browser, then sent over a secure connection, and temporary data is removed after processing. For very sensitive files, keep only the pages you need with Extract Pages before you summarize.
How accurate are the summaries?
Summaries are written from your PDF text only, so they stick to what the document says. For important decisions, such as a contract or a medical letter, use the summary as a map and check key figures against the page. A follow-up like "What is the notice period?" takes you straight to a specific detail.
Can I summarize a research paper or lecture notes?
Yes. Research papers, lecture notes, and textbook chapters are some of the best uses. Choose Long and Detailed to keep methods, findings, and conclusions, or Short for a quick recap before class. Then ask follow-ups like "What were the main results?" or "Explain this in simpler words."
Can I summarize a PDF on my phone?
Yes. Summarize PDF works in any modern browser on iPhone, Android, Mac, and Windows, with no app to install. On a phone, the summary and chat fill the screen so you can read comfortably and type follow-up questions with one hand, even on the go.
How long can my PDF be?
Free summarizes PDFs up to 15 pages with the Fast style and 10 pages with Detailed, which suits most reports, articles, and chapters. For a whole book or a long case file, split it into chapters with Split PDF and summarize each one for a clearer overview.
What if my PDF is a scan or a photo?
Scanned pages are pictures, so there is no text to summarize yet. Run the file through OCR PDF first to add a searchable text layer, then upload the new PDF here. As soon as the text can be selected, Summarize PDF can read it and write your overview.
What is the difference between Summarize PDF and Chat with PDF?
Summarize PDF starts with an overview, which is ideal when you need the big picture first. Chat with PDF skips the summary and goes straight to your questions. For exam prep, Generate Questions turns the same PDF into multiple-choice, true-or-false, or open-ended quiz questions.
