PDFs & slides

Write right
on the slides.

Import your lecture slides and readings, highlight what matters, and make room under any slide for the things your professor only said out loud.

How it works

From the slide deck to your notes.

01Import

Bring in slides, readings and worksheets as PDFs or images, from your files or the share menu.

02Annotate

Every pen and the highlighter work on the page. The PDF’s own text stays searchable.

03Make room

Add blank space under any slide, or a blank page between two of them.

04Ask about it

The margin reads your slides along with your notes, so its answers can point to the slide.

Up close

Room for what wasn’t on the slide.

Pull a slide open and blank paper appears underneath it, in the same notebook paper you chose. Your notes stay attached to that slide when you print or export.

FAQ

About PDFs.

Can I import PowerPoint or Keynote slides?

Export them as a PDF first, which PowerPoint, Keynote and Google Slides all do from their File menu. Importing slide files directly is planned.

Is the original PDF changed?

No. Your ink sits on its own layer. You can export the PDF with or without your notes.

Can I search inside imported PDFs?

Yes. Search finds text in your PDFs as well as your handwriting and typed notes, and opens the right page.

Is there a size limit?

Long readings and full slide decks are fine. If a file ever fails to import, tell us and a person will look at it.
