    Routine

    Routine is a work operating system that helps individuals and teams organize and manage their work efficiently. Routine centralizes work (tasks, meetings, tickets, clients etc.) from third-party services (GitHub, Salesforce, HubSpot, Slack, Dropbox etc.) into a graph-based unified workspace allowing seamless cross-referencing, 360-degree overview, data enrichment and visualization. By integrating with existing tools, Routine connects and enriches fragmented information, allowing users to track projects, collaborate efficiently, and make better decisions without having to constantly switch between multiple apps. Its data-driven and local-first approach ensures the information remains accessible and performant even without cloud connectivity.
