What is the difference between a chatbot and an AI agent?
Where the answer comes from and what it can do with it. A chatbot answers from what is written in your documentation: it handles the questions whose answer is the same for everybody. An agent also reads the account state of whoever is asking and can run actions, so it resolves the questions that depend on that specific customer too.
Short answer
Where the answer comes from and what it can do with it. A chatbot answers from what is written in your documentation: it handles the questions whose answer is the same for everybody. An agent also reads the account state of whoever is asking and can run actions, so it resolves the questions that depend on that specific customer too.
In detail
The exact boundary
"How do I change plan?" is a chatbot question: the answer is written down and it is the same for everyone. "Why was I charged €340?" is not, because it depends on that account, that month and that plan. No article, however well written, answers the second, and writing more articles does not change that.
Why the split matters
At a SaaS, the second group is usually close to half the volume, and it is the expensive half: the one that today makes somebody open the admin panel, check three things and come back. A documentation bot does not touch any of it, however good it is.
How to know which you need
Take a hundred real conversations and sort them into two piles: answered with general information, and needing the account checked. That percentage decides, and it takes an afternoon. If the first pile is the majority, a well-built chatbot covers most of it. If it is the second, a chatbot will disappoint you.
The word "agent" means two things
In support, an agent was the person answering. Since 2023 it is also the software that answers with nobody involved. It is worth saying "AI agent" for the second: both live on the same team, and sentences like "the agent escalates to the agent" help nobody.

Other questions in this thread
Can an AI agent see each customer plan and data?
Only if you connect it, and that is exactly the line separating a documentation bot from an agent. By default an AI system sees only what you give it: give it documentation and it answers documentation; give it read access to your API as well and it can check the plan, the usage or the last invoice of whoever is asking, and answer with that fact.
Is a knowledge base the same as a help centre?
Almost. The knowledge base is the content — the articles — and the help centre is the public site where they are published, with its search and navigation. In daily conversation the two are used interchangeably and it rarely matters, except when comparing tools: some sell the first and some the second, and the price is not the same.
Does an AI helpdesk replace my support team?
No, and anybody telling you otherwise is selling something. It replaces one specific part of the work: the repeated, the documented, and a good share of what gets resolved by checking one account fact. Anything needing judgement, anything angry and anything nobody had seen still belongs to a person — usually the part you hired that person for.
