What is an AI agent?

An AI agent is a software program that uses a large language model to understand a goal, decide what to do, and take actions like sending a message, calling an API, or updating a record, often across multiple steps and with limited human input.

The difference between an AI agent and a chatbot is action. A chatbot replies with text; an agent can actually do the work: look up an account, book an appointment, process a change, and write the result back to a business system. It does this by calling "tools" (functions and APIs) the way a person would click through software.

Good agents run with guardrails: a defined scope, safety rules, and human-in-the-loop approval for sensitive actions, so a person can review or step in before anything irreversible happens.

How Tether AI does this

Tether AI lets companies build agents that work across calls, texts, and email, call real business tools mid-conversation, and update the system of record, all with human-in-the-loop controls.
