One click calendar scheduling plus powerful email management tools.

The unified productivity engine for tasks, email, and calendars in a single-pane workflow.

Legend (formerly Moo.do) is a sophisticated productivity architecture designed for users who require a high-density, centralized workspace. By 2026, Legend has positioned itself as the premier solution for 'Context Switching Reduction,' integrating Gmail, Outlook, and iCloud directly into a hierarchical outliner. Its technical core revolves around a multi-pane interface that allows for the simultaneous viewing of tasks, emails, and calendar events in a unified, synchronized environment. Unlike standard task managers, Legend treats every piece of data as a node, enabling deep nested hierarchies and cross-linked references. The 2026 iteration features 'Legend AI,' which utilizes local-first LLM processing to automatically prioritize tasks based on email sentiment and calendar availability. The platform's architecture is built for performance, utilizing a local-first data model that ensures zero-latency interactions even with massive databases of over 100,000 items. This makes it an essential tool for project managers, developers, and executives who need to bridge the gap between communication (email) and execution (tasks) without leaving a single interface.
