This tool is one small part of Leo
Leo is an intelligent working environment. It understands how an organisation works, keeps track of projects, tasks, meetings and matters, and helps turn what you know into coordinated action. You stay in control of every consequential decision.
Know
Leo holds the context: people, systems, commitments and live work.
Decide
It reads situations, sets out options and prepares plans for you to approve.
Act
Approved plans become coordinated work across people and agents.
