Typewriter, Text Box and Callout tools let you add text comments anywhere on the page. You can use the Text Box tool to type text in a box that is movable and resizable. Unlike a pop-up note, it always remains visible on the document.

You can use the Typewriter tool to add additional text directly on the page. Different from Text Box, the Typewriter box is hidden after you finish typing.

The Callout tool serves to create a callout box with an arrow pointing to a particular spot on the page. The callout box expands vertically as you type so that all text remains visible. It can be useful especially when you want to associate a comment with a related section of text or image.
