PDF Reading and Annotations

The PDF viewer inside a study session lets you mark up a document while you study it, not just read it.

How to use it

1. Open a file in a study session.
2. Select text to highlight or underline it, or add a sticky note at a point in the document.
3. Click the bookmark icon on a page to save your place.
4. Use the highlights/notes sidebar to jump between everything you’ve marked.

What you should see

Colored highlights and small sticky-note icons directly on the page, plus a list of all annotations and bookmarks for that file.

Good to know

• Annotations and bookmarks are saved per file, so they’re there the next time you open it in any study session.
• For a distraction-free, full-screen PDF reader without the study tools, use /camp/adobe-pdf instead.

If it doesn’t work

Highlight disappears after reloading: make sure you selected actual text, not an image region; scanned PDFs without a text layer can’t be highlighted.
