FAQ
Questions and answers
Will my highlights show in Adobe Acrobat or Preview?
Yes. They are standard PDF annotations, the kind every PDF reader shows and can list.
Can I change or delete a note later?
Yes: click it to open its card with the author, the date, the color and the comment, and change it or delete it.
Can I highlight text in a scan?
Recognize the text of the scan first, then highlight it like any other text. Or draw over it with the Pen.
Do I need an account?
Not to annotate: a guest’s notes are signed “Guest”. To download the PDF, create a free account.
