Yes, you can use Author-it to create training material, including Student and Instructor Guides (PDF), HTML5 elearning and assessments, and HTML5 presentations. All of this is created from the same content source. There's good documentation on our knowledge center here: http://kc.author-it.com and feel free to reach out to us directly via the Contact form on our website. Hope this helps!
