Everything you need to study a PDF
A clean reading experience with the tools students, researchers and professionals actually use.
Personal library
Import PDFs from Files and organize them with covers, titles and authors you can edit.

Dynamic bookmarks
Bookmarks remember the chapter and the first line of the page, so you always know where you were.
Chapter detection
Automatic chapter indexing to navigate and to group your highlights and summaries.
Export
Export your highlights and notes to use in your study workflow.
Private by design
Your library, highlights and notes are stored on your device. No account needed.
Smart Summary
Summarize exactly what you need, in the format you need it.
- Any scope: a page, a chapter, a page range, a selection, your highlights or the whole document.
- Any format: summary, key points, explain simply, or study questions.
- Flashcards: turn study questions into flashcards.
- Apple Intelligence on supported devices (iOS 26+).
- Offline fallback: summaries still work without Apple Intelligence.
Built for dual-panel reading
On supported dual-panel layouts, read the PDF on one side while summaries, highlights and notes stay on the other, aligned to the hinge. Fold back to a sheet without losing your place.
