Learnosity Author is comprised of two parts:

Author API

An embeddable Javascript API provide a best-in-class authoring UI and UX experience, designed to be seamlessly embedded into your own Content Management System, or into your teacher or instructor facing front end platform or Learning Management System.

Author Site

A hosted authoring platform, built on top of the Author API, designed to provide an out-of-the-box authoring experience for those who need their own internal platform for assessment content creation.

In this section, ("What is Learnosity Author") we'll dive into a little more depth on the use cases where each of these tools is most useful, and help you decide when to use one or the other.
