The Public Preview feature of Quintype allows you to share individual stories with people outside the Quintype platform, for example - sharing a story with a sponsor for review. Clicking on the preview icon in the workspace page will open the story preview page in a new tab.
Simply share the URL of your current story with someone - over mail or chat. They can open the link in their browser to see the content, but will not be able to edit or comment the content in any way.
