What is AI Agent?

Home > Glossary > AI Agent

An AI agent is a software system that can interpret a goal, decide what steps to take, use tools or data sources, and act with limited human intervention. In ecommerce, agents can assist with discovery, service, merchandising, procurement, and transactions.

Unlike a simple prompt-response chatbot, an agent works toward an objective across multiple steps. It can interpret context, choose a tool, inspect the result, decide what to do next, and repeat the process until the task is complete or a boundary is reached. In commerce, the useful part is not just reasoning but controlled access to real systems such as search, PIM, ERP, CRM, OMS, checkout, and support platforms.

An ecommerce AI agent commonly combines:

• A language or reasoning model that interprets goals and plans actions.

• Tools or APIs for retrieving data and performing approved operations.

• Memory or session context so the agent can keep track of the user, order, or workflow.

• Policies and guardrails that restrict data access, financial actions, and irreversible changes.

The distinction matters because an agent can create operational consequences. A wrong answer from a chatbot is a content problem; a wrong action from an agent can create an order, expose account-specific pricing, or trigger a refund. Mature implementations therefore pair autonomy with deterministic business rules, permissions, observability, and human review for high-impact decisions.

Example: A service agent can read an order, check the carrier status, apply the merchant’s return policy, and prepare a return request, while a deterministic tool decides whether the return is actually eligible.
