With Google Drive, you can create spreadsheets, documents, presentations and drawings that you can share with others. The URL widget in Justinmind Prototoyer, lets you add a live view of your docs which can be edited in real time! (if the user has editing permissions).
Just follow these easy steps:
1. Create your doc in Google Drive and get the link to share.
2. Shorten your link here: http://goo.gl/, or by using any other URL shortener https://bitly.com/
3. Insert a URL widget in Prototyper with the shortened link
Try adding your own stuff using the URL Widget and the HTML Widget. Your prototypes can embed Videos, Google Maps, Forms,… whatever you want!
