Tango is a process capture tool that takes screenshots of the steps in your Workflow and automatically transcribes descriptions of each step. For example, when you click a "Submit" button, Tango will take a picture of the button you click and label it "Click on Submit", but it won't record you moving the mouse over to press the button.
On Tango Pro and Enterprise plans, you can transform any process you've captured into an embedded video, which users can then watch, rather than scroll or click through. You can learn more here.
