Summarize a long PDF the way you need it
There is no single summarize button. Upload the PDF, then ask for the summary you want: a chapter in ten points, the argument of section four, the conclusion in plain words.
Ways to ask for a summary
A long PDF is not one summary problem but several. Sometimes you want the shape of the whole thing: what it covers, in what order, where the weight sits. Sometimes you want one chapter compressed into ten points. Sometimes you only need to know whether a section says anything you did not already know. A fixed summarize button answers one of those and ignores the rest, which is why summarizing here is a conversation rather than a click. You ask in the words you would use — outline this in ten points, what does section four argue, give me a paragraph on the method — and you can ask again at a different length or a different level of detail without starting over. The second reply is a different summary, not the first one reworded.
A sensible order of asking helps more than a clever prompt. Start by asking what the document covers and where each part sits; that answer comes back with page references, which gives you a map you can click. Then summarize only the parts the map says matter, section by section, because one answer stretched over four hundred pages is thin by arithmetic while a chapter at a time gives you something you can revise from. When a point in a summary surprises you, follow its page reference and read the original sentence before you write it into your notes. A summary is a compression, and compression loses things: treat one as a map of where to read closely, not as a substitute for having read.
What you get, on every document
- Answers that cite the page
- Replies name the pages they came from, as chips that scroll the viewer straight there so you can read the source yourself.
- Grounded in your document
- It answers from the file you uploaded and says so plainly when your question is not covered, rather than inventing something plausible.
- PDFs up to 25 MB
- One document per chat, shown beside the conversation with real text selection — highlight a passage and ask about that exact part.
- Scans read automatically
- Pages with no selectable text are read with OCR instead, page by page, so a scanned or photographed document still works.
- Six interface languages
- English, Bangla, Spanish, Indonesian, Arabic and German — and replies come back in whichever language you ask in.
- Turn it into practice
- The same document can become practice multiple-choice questions, spaced-repetition review and mock exams once you have read it.

PDF summaries FAQ
Is there a one-click summarize button?
No. You upload the PDF and ask for the summary you want in the chat beside it. That costs a sentence rather than a click, and in return you get a summary at the length and level of detail you asked for, covering the part of the document you named, with page references you can follow back into the text.
Can I summarize one section or a range of pages?
Yes, and it usually beats asking about the whole document. Name the part you mean — the second chapter, the discussion, pages 40 to 60 — and the answer stays inside it. A series of narrow summaries read in order gives you a far more usable picture of a long document than a single summary trying to cover everything at once.
Can the summary come back in a different language from the PDF?
Yes. Ask in one of the languages the interface supports and the summary arrives in that language, even where the document itself is written in another. The document is not translated: what comes back in your language is the summary and the answers, so a page you then open to check will still be in the original wording.
Should I summarize before reading or after?
Both, for different reasons. Before, a summary of what the document covers and in what order tells you which parts you actually need, which can be the difference between reading two hundred pages and reading thirty. After, summarizing a section you have already read is a way of testing yourself: compare what comes back with what you would have written, then reread the pages where the two disagree.

Upload the PDF, name the section and the length you want, and follow the page references back into the text.
