Questions
How do I summarize a chapter?
Upload the chapter as a PDF, .docx, or EPUB, take a photo of a page, or paste the text. Press Summarize the chapter. You get up to 6 sections, each with a heading and a short summary.
Can I summarize a whole book?
It works best one chapter at a time. A long file is read up to a limit on the free tool, and the result tells you when it stopped early. Split a book into chapters for a better summary of each.
Does it work on an ebook?
Yes. EPUB files work, as long as they are not locked with copy protection. Word, OpenDocument, RTF, Markdown, and plain text work too.
What if I only have the printed book?
Take a photo of the page. Hold it flat, use good light, and fill the frame. The AI reads the text and summarizes it.
Can I get a shorter version?
Switch to the outline view for a quick scan, or press Key points under the summary for the main facts as a list. It can also read the summary aloud where your browser supports it.
Is it free?
Yes, no account and no card. There is a small daily limit on free runs. Sign up free to keep the summary with flashcards and a quiz from the same chapter.
