This runs in the Acrobat app - there is no separate API for this task.
In Acrobat, a comment is usually text-based feedback, like a sticky note or a text box. An annotation is more about marking up the document visually, such as highlighting text, underlining, or drawing shapes. Both are used to give feedback and are part of the 'Comments and Annotations' feature set.
Yes, if you share a PDF that has comments and markups, the other person will see them. Comments are a separate layer of data within the PDF. To make sure your personal notes do not leak, you must 'flatten' or 'sanitize' the document before sharing. Use the 'Protect > Sanitize' option in Acrobat to remove all review notes and comments.
It is important to sanitize a PDF to protect your privacy and prevent unwanted information from being shared. Comments, highlights, and other markups are often internal review notes. If you send a 'final' version without sanitizing, these notes could be seen by others. Sanitizing removes this extra data, making the document clean and truly final.
