Agentic commerce

Definition

Commerce transactions initiated, researched, or completed with an AI agent acting on the shopper's behalf, rather than a human clicking through a storefront unassisted.

Defined in The Agentic Commerce Glossary.

How else it gets framed

The same term carries different emphasis depending on the surface it’s used on. Both readings are correct.

Commerce where an AI agent — on-site (a Brand Agent, on-site AI search) or off-site (ChatGPT, Perplexity, Rufus) — reasons over a store's product data on the shopper's behalf, and in some flows completes the purchase itself. The store's job shifts from persuading a human eye to answering a machine's questions correctly.
