OpenTag serves as a versatile AI collaborator within Slack and Microsoft Teams, seamlessly integrating with the company’s context to alleviate the workload of teams rather than merely responding to queries. By mentioning it in a conversation thread, users can have it organize tasks, utilize integrated tools, execute the necessary work, and deliver the results back to the original conversation.
