Easily annotate a variety of media.

Annotations can be added quickly and easily using the built-in annotation editor.

Easily annotate video, audio, images, source code, text, and maps* using Scalar’s built-in media annotation tools. Video and audio annotations appear superimposed live on the page as media plays, and you can embed links directly to the annotated portion of a media file. And, because annotations are also pages in their own right, they can contain not only text, but media as well making it possible to annotate just about anything in your book with anything else. Want to annotate source code with poetry? Or audio with video? Scalar makes it possible.

* Map annotation support via integration with HyperCities.
