Intercom
LeaderIntercom ships Fin, a native AI agent that can resolve support requests without human involvement, and it works well out of the box. For teams building custom agents, the APIs expose full conversation history, user attributes, and the ability to send replies programmatically. The Custom Bots framework lets you define decision trees and actions that connect to external systems. Handoff is where Intercom stands out: when your agent hits its limits, it transfers context to a human agent with the full conversation visible and no context lost. The pricing reflects the premium positioning; this is enterprise tooling, and smaller teams may find it excessive for basic ticket management.
