Tango is a tool designed to help users create step-by-step guides, called "Tangos," to document processes or share knowledge efficiently. It captures processes on a screen, turning them into interactive workflows that can be shared without needing meetings, screen shares, or videos. Tango allows users to create process guides by capturing browser or desktop actions, annotate images, blur sensitive information, and share guides through various formats, such as URL links or embedded in other tools.
