What is an AI agent?
An AI agent is software that understands natural language and acts— it books a meeting, qualifies a lead, takes a payment — where a classic chatbot only answers. This page defines the term, contrasts it with a chatbot, and shows what an agent does on a website.
Definition of an AI agent
An AI agent combines four things: a language model (LLM) to understand and respond, a knowledge corpus (your pages, FAQ, documents) to stay accurate, a set of tools to act in the real world (calendar, payment, CRM), and memory to keep context across the conversation. That combination is what turns a passive responder into an active agent.
Chatbot vs AI agent: the difference that changes everything
| Chatbot | AI agent | |
|---|---|---|
| Core behaviour | Answers | Answers and acts |
| Logic | Scripted flows / FAQ lookup | Reasons over your content (LLM) |
| Language | Predefined intents | Open natural language, multilingual |
| Outcome | “Here is our phone number” | Books the meeting in the chat |
| Tools | None or rigid integrations | Calendar, payment, CRM, recommendations |
| For agents (A2A) | Invisible to other AIs | Discoverable via MCP |
What an AI agent can do on a website
Beyond answering questions 24/7, an AI agent can qualify a visitor and capture a lead, book a meeting in your calendar, take a payment, recommend products, and escalateto a human when needed — including over the phone via voice.
How an AI agent works
Your content is injected into the model’s context so it answers from your material rather than improvising. When the visitor asks for something actionable, the agent calls the matching tool — check availability, create a booking, take a payment. Through the Model Context Protocol (MCP), the same agent can also be discovered and used by other AIs: this is the agentic web.
AI agents, GDPR and hallucinations
A trustworthy AI agent runs on EU-friendly hosting, asks for consent before collecting personal data, and shows an “AI-generated” disclaimer. Grounding it in a curated corpus and forcing it to cite sources keeps hallucinations marginal, and a human hand-off covers the edge cases.
How to create an AI agent for your site
You describe your business, choose the actions the agent may take, and install it with one line of script — no code. Our step-by-step guide walks through it:

What is an AI agent in simple terms?
An AI agent is a piece of software that understands natural language, reasons over a body of knowledge you give it, and takes real actions on your behalf — answering questions, qualifying leads, booking meetings or taking payment. Unlike a basic chatbot, it does not just reply: it acts.
What is the difference between a chatbot and an AI agent?
A chatbot answers — it follows scripts or pulls from a FAQ. An AI agent acts: it understands open language, reasons over your content, and triggers actions through tools (calendar, payment, CRM). The chatbot is an answering machine; the agent is an assistant that moves work forward.
Can an AI agent act on its own, like booking a meeting or taking payment?
Yes, within the actions you allow. Connected to a calendar it books meetings; connected to Stripe it can take a payment; connected to your CRM it logs a lead. You decide the scope — the agent never acts outside the tools you have enabled.
Do you need to code to have an AI agent?
No. Modern platforms let you create an AI agent from a dashboard: you describe your business, pick the allowed actions, and install it with one line of script (or a plugin on WordPress). No development is required.
Is an AI agent GDPR compliant?
It can be, and should be. Look for EU hosting, the ability to route AI processing to European providers, explicit consent before collecting personal data, and an “AI-generated” disclaimer. These controls make an AI agent compatible with GDPR.
What is the agentic web?
The agentic web is the shift from pages browsed by humans to services consumed by AI agents. Via standards like the Model Context Protocol (MCP), your agent becomes discoverable and usable by other AIs (Claude, Cursor), not just by visitors on your site.
Can an AI agent hallucinate?
It can, but the risk is largely controllable: ground it in a well-structured knowledge corpus, use tools that force it to cite sources, show a disclaimer, and escalate to a human when it leaves its scope. Properly framed, hallucinations become marginal.
How much does an AI agent cost?
Entry-level agents are free for low volumes (e.g. 50 conversations/month). Paid plans typically run from around €29/month for a single site up to a few hundred euros per month for agencies managing many agents with white-label.
