4Choose the scope: This page or Whole document.
5Tap badges like "p. 12" in the answer to jump to that page; tap Listen to hear the summary aloud.

After the summary: ask, make cards

In the same chat you can ask things like "What is the termination clause?" or "Explain the formula in section 3"; follow-up questions cost a quarter of an Ai page. For class notes, Make study cards turns key facts into cards, and Make a quiz lets you test yourself.

For a letter, bill or official notice, use Explain document in the reader's ⋮ menu: it lists who sent it, what they want from you, the deadline and the amount in separate boxes.

Scanned PDFs and hard pages

In PDFs made of photos or scans, the text is first recognised on your device and then summarized. For a page with handwriting, tables or formulas, Read hard page in the reader's ⋮ menu has Ai read the page from its image.
