Tango auto-generates step-by-step how-to guides with annotated screenshots directly from browser actions, eliminating manual documentation work for teams.
Tango is a workflow documentation platform that watches what a user does inside a browser or desktop application and automatically produces a formatted, annotated step-by-step guide complete with numbered screenshots, callout highlights, and descriptive text for each action taken. The core value proposition is the elimination of the manual documentation effort that traditionally follows any software process: instead of taking screenshots, pasting them into a document, annotating each image, and writing accompanying text, a team member simply performs the workflow once while Tango records it, and the finished guide is available immediately. This automation is particularly valuable for operations, customer success, and IT teams that maintain large libraries of internal SOPs and training materials that become stale as software changes and require constant rework to keep current.
