Zendesk AI agents are AI-powered chatbots that interact with your customers on messaging, email (including API and web form), and voice (EAP) channels. They can have conversations with customers and perform actions in authorized systems autonomously, automating and resolving issues so that your human agents can focus on more complex work.

About AI agent functionality
Zendesk AI agent functionality covers all levels of automation, from quick, self-service workflows to more complex workflows integrated with other platforms. You can start automating in just minutes with AI agents that answer customer questions based on content from your trusted knowledge sources.
From there, you can move on to more advanced features such as goal-oriented generative procedures, scripted dialogues, authorized actions, and API integrations with systems you already use. Through it all, advanced analytics are available to help you measure your automation success.
AI agents use agentic AI to solve complex user requests with limited direct human supervision. They’re capable of autonomous decision-making, planning, and adaptive execution throughout the course of a conversation. AI agents interact with your customers in a natural, human-like way, engaging in small talk and working through complex or vague issues by identifying the necessary next steps and asking follow-up questions where needed.
Usage of AI agent functionality is measured through automated resolutions. This means you pay only for customer requests that were successfully resolved by an AI agent, without any escalation to a human agent. Each account includes an allowance of automated resolutions based on their plan, and you can buy more if needed.

Zero-training AI agents
Zero-training AI agents are a previous generation of Zendesk AI agents that used generative AI–based use cases to understand customer requests and link to scripted dialogues. Much of the configuration performed for zero-training AI agents (such as use cases) remains the same for the current, agentic AI generation of Zendesk AI agents. The important distinction is that AI agents with agentic AI can also use generative procedures.
Important date to know:
- As of May 11, 2026, zero-training AI agents are considered legacy functionality. These types of AI agents can no longer be created, but you may have already created some that you continue to maintain.
For more information, see Using AI agents.
