The one sentence difference
A chatbot answers. An agent acts. A chatbot takes a message and returns text; a person decides what to do with it. An agent is given a goal and a set of tools (search, a CRM, an email system, a spreadsheet) and decides for itself which tools to use, in what order, until it judges the goal met.
That difference sounds small and is not. The moment software can act, the questions change from "is this answer good?" to "what is it allowed to do, who checks it, and what happens when it is wrong?"
Four things that get called "AI" in business
Anthropic's engineering guidance draws a useful line between workflows, where language models and tools follow predefined code paths, and agents, where the model directs its own process and tool use. Adding the simpler chatbot and assistant categories gives four options.
Chatbot, assistant, workflow and agent compared
| Criterion | Chatbot | Assistant | Workflow with AI steps | Agent |
|---|---|---|---|---|
| What it does | Answers questions in a conversation | Helps one person with tasks when asked | Runs fixed steps, with AI doing some of them | Chooses and uses tools to reach a goal |
| Who decides the next step | The user | The user | The designer, in advance | The model, at run time |
| Can it take actions? | Usually not, or only narrow ones | Only when the user asks | Yes, the predefined ones | Yes, any its tools allow |
| Predictability | High | High | High: same path every time | Lower: path varies by case |
| Cost per task | Low | Low | Low to moderate | Higher: more model calls per task |
| Oversight needed | Content review | The user reviews as they go | Test once, monitor runs | Permissions, approvals, logs and ongoing checks |
| Marketing example | Website FAQ bot answering delivery questions | Drafting a campaign email with a marketer | New lead is enriched, scored and added to the CRM | Researching a list of target accounts and deciding who to contact and why |
Why agents cost more to run safely
More model calls, more cost
Agents plan, call tools, read results and plan again. Anthropic has published that, in its own research system, agents used roughly four times the tokens of a chat interaction and multi agent systems roughly fifteen times. That can be worth it for high value tasks. It is waste for a task a fixed workflow could do.
More ways to go wrong
OWASP's security guidance for language model applications lists "excessive agency" as a named risk: giving a model more tools, permissions or autonomy than the job needs, so that an unexpected or manipulated output leads to a damaging action. A chatbot that gives a wrong answer is embarrassing. An agent with send permissions that emails the wrong list can be a data protection incident.
More projects fail
Gartner predicted in June 2025 that over 40% of agentic AI projects would be cancelled by the end of 2027, citing escalating costs, unclear business value and inadequate risk controls. That is a forecast, not a measurement, but it matches the pattern above: agents chosen for novelty rather than fit.
So, is there an agentic shift?
Yes, in a specific sense: tools that could only talk can now act, and most major business software is adding agent features. HubSpot, Zapier, Make and n8n all now offer agent capabilities. What has not changed is which problems need that ability. The shift is in what is available, not in what every business should buy.
A decision rule you can use
Ask four questions about the process you want to improve.
- • Can you write the steps down in advance? If yes, you need a workflow, not an agent. Most lead routing, reporting and content publishing is like this.
- • Does each case need different steps? If inputs vary so much that no fixed path works (open ended research, messy inbound requests), an agent may help.
- • Is the value per task high enough to pay for more calls and more checking? Researching a strategic account, yes. Tagging a newsletter signup, no.
- • Can you limit what it may do and review what it did? If you cannot restrict its permissions and read a log of its actions, do not deploy it.
If the answers are no, yes, yes, yes, an agent is a reasonable choice. Anything else points to a chatbot, an assistant or a workflow.
What this looks like in marketing
AfM's published automation case records follow one pattern: a workflow with one agent step inside it. The inbound lead system, work Jakub delivered in 2025 before founding AfM, uses a fixed path (form, enrichment, CRM, notification) with a Relevance AI agent doing only the research step, and leads it cannot enrich confidently are flagged for a person rather than pushed through. That is a deliberate design: the agent's freedom is limited to the one step that needs judgement about messy inputs.
The same principle runs through how AfM works as a managed service. Our internal system supports research and production; a person decides priorities and reviews what ships. For the longer view of how far autonomy can go, see autonomous marketing systems explained.
FAQ
Is ChatGPT a chatbot or an agent?
In ordinary use it is an assistant: it answers and helps when asked. Some of its features, such as tools that browse or carry out multi step tasks, behave more like agents. The label matters less than what it is allowed to do.
Can a website chatbot become an agent?
Yes, if it is connected to tools such as booking, order lookup or refunds and decides when to use them. At that point it needs the permission limits, logging and escalation to a person that any agent needs.
Are AI agents safe to let send emails to customers?
Only with limits: a restricted list, templates or approval before sending, and a log of every send. Most businesses should keep a person approving outbound messages until the agent has a long checked record.
Do I need an agent to use AI in marketing?
No. Most of the value available today comes from assistants helping people draft and analyse, and from workflows with an AI step. Agents are one option for variable, high value tasks.
