Messaging Agents

AI agents that manage your calendar

Calendar work is the most common capability in the whole set, just ahead of task management. The useful distinction is between agents that read a calendar and agents that write to it, because almost all of them do the first and far fewer do the second well.

What the claim actually covers

Reading is straightforward: the agent sees your week and answers questions about it. Writing means creating events, moving them, and dealing with the consequences when two things collide.

The harder version is conflict resolution and multi-party scheduling, where the agent negotiates with other people rather than just editing your grid. Catch states that it resolves scheduling conflicts and works across multiple calendars; several group agents coordinate times between several people, which is the same problem in a different shape.

Google Calendar is named by 44 of the 66 listings that name any integration, beside Gmail's 45.

What these connect to

Named by the agents that state this capability. An agent that names none is not necessarily unconnected, it may simply not say.

Other jobs people hand over

Most of these agents do several of these, so the same product turns up under more than one.

Building one instead? The infrastructure side is a separate half of this site: every provider that carries these messages, what they charge, and what the headline price leaves out. The guides cover getting an agent into iMessage, WhatsApp and SMS.
