My Simpleshow is a tool for building short "explainer" videos. It includes a number of template storylines that users can select as a starting point. For example, their educational templates include "explain a mathematical formula," "interpret literature," "introduce a biological process," and others. There are also professional storylines (like "introduce your startup") and personal storylines (like "invite someone to an event"). After selecting a storyline, users flesh out the template script with their specific details, select illustrations, and graphics, and select a soundtrack. A number of sample explainer videos can be found under "examples" in the menu at the top right of the site. My Simpleshow is free for personal or classroom use. A variety of paid plans are also available for business use. My Simpleshow works in any modern browser.
