AI agent
Last updated June 29, 2026 · by Tal Gerafi
An AI agent is a system built on a large language model that pursues a goal across multiple steps — deciding actions, using tools, and reacting to results — rather than answering a single prompt in one shot.
An AI agent is more than a chatbot. A chatbot answers; an agent acts — it breaks a goal into steps, chooses what to do next, calls tools, observes the outcome, and adjusts. The model is the brain; the agent is the brain plus hands and a loop.
How it works
A large language model decides the next action based on the goal and what it has seen so far. Tools give it reach — searching files, running commands, querying an API. After each action it reads the result and decides again. A coding agent is one kind of AI agent specialized for software; the same pattern powers research, support, and operations agents.
Why it matters for B2B sites
Agents are how AI moves from "draft me some text" to "do the task." For a website, that means an agent can plan content, build a page, or audit SEO end to end. The trade-off is reliability: more autonomy means more room for a confident mistake, so consequential steps need a human-in-the-loop. Greeto runs a small team of focused agents, each owning one step — described in Building websites with Claude Code.
