The list is accurate and not much help when you are deciding what to build,\nbecause almost every product now claims most of it. One question sorts them faster: what\nhappens to the output?\n\nA chatbot's output is words. Someone reads them and decides what to do. An AI agent's output is\nactions. It looks something up, changes a record, sends a message, then looks at the result and\ndecides what to do next, without waiting for a person in between. That single difference moves\nthe risk, the cost and the work needed to run it safely, and it is the right place to start.\n\n## The difference between an AI agent and a chatbot in one line\n\nA chatbot answers; an AI agent acts. Both may use the same language model underneath. What\nseparates them is whether the model's output stops at a person or goes straight into your\nsystems.\n\n| | Chatbot | AI agent |\n|---|---|---|\n| Output | Text a person reads | Actions in other systems |\n| Who acts on it | The person reading | The agent itself |\n| Typical tools | None, or read-only lookups | Read and write access to the systems it works in |\n| Shape of the work | One question, one reply | A goal, broken into steps, repeated until done |\n| A mistake looks like | A wrong or invented answer | A wrong change, sent message or completed transaction |\n| What limits the damage | The reader's judgement | Permissions, approvals, limits and logs you build |\n\nA chatbot can be wrong in a sentence. An agent can be wrong in your database. Everything else\nin this comparison follows from that.\n\n## What a chatbot is, and what an AI chatbot added\n\nA chatbot is software that holds a conversation. Older ones followed scripts: buttons, keyword\nmatches and decision trees that broke as soon as a question arrived in an unexpected form. AI\nchatbots replaced the script with a language model, so they understand questions phrased in\nany way and can answer from documents you give them, such as a help centre, a policy library\nor a product catalogue.\n\nWhat an AI chatbot still does not do is act. It can explain the returns policy, summarise a\ncontract or draft a reply. The customer, the employee or the support agent decides whether to\nuse what it said. That human step is also its safety margin: a wrong answer reaches a reader\nwho can question it before anything changes.\n\n## What makes something an AI agent\n\nAn AI agent is given a goal rather than a question, and it has tools it can use to reach it. It\nplans a step, uses a tool, reads what came back and decides on the next step, repeating that loop\nuntil it judges the goal is met or it runs out of options.\n\nFour things make a system an agent rather than a chatbot with extras:\n\n- **A goal, not a prompt.** \"Reschedule every appointment affected by Friday's closure\" rather\n  than \"what is the policy for closures?\"\n- **Tools that do things.** Access to a calendar, a CRM, an inbox, a payment system or a\n  database, through interfaces that change something when called.\n- **A loop.** The agent decides its own next step from the result of the last one, so the path\n  through the task is not fixed in advance.\n- **Permissions.** Whatever credentials the tools run under define the most the agent can do.\n  That limit is set by whoever builds it, not by the model.\n\nBuyers most often skip the last item, yet it sets the ceiling on the damage a confused or\nmanipulated agent can do.\n\n## AI agent vs chatbot vs assistant\n\nAn AI assistant sits between the two. Like an agent, it can use tools: it can find a time in\nyour calendar, fill in a form or prepare a refund. Like a chatbot, it stops before anything\nchanges, and a person confirms each action. In practice the three are points on one line rather\nthan separate categories:\n\n1. **Chatbot:** answers from what it knows or has been given. A person does everything.\n2. **Assistant:** prepares actions with tools. A person approves each one.\n3. **Agent:** takes actions within limits. A person reviews exceptions and samples the rest.\n\nMost useful systems in production sit at step 2, or at step 3 for a narrow set of actions that\nare cheap to undo. Moving along the line is a decision made per action, not per product.\n\n## What is the difference between an AI agent and ChatGPT?\n\nChatGPT is a product; \"AI agent\" describes what a system is allowed to do. Used in a browser to\nask questions and draft text, ChatGPT works as a chatbot or an assistant: it writes, and you\ndecide what to do with the result. General-purpose chat products increasingly add features\nthat browse the web or carry out tasks for the user, which moves them toward the agent end of\nthe line for those tasks.\n\nFor a business, the more useful question is not which product it is but what it would be\nconnected to. A chat product with no access to your systems cannot change them, however capable\nit is. A modest model wired into your order system with write access can. The difference is\nmade by the integration and its permissions, which is why it has to be designed rather than\nbought as a feature.\n\n## Agentic AI vs AI agents\n\nAgentic AI describes a degree of autonomy; an AI agent is a system that has some. The terms\nare often used interchangeably, but the distinction is practical. \"Agentic\" is a property you\ncan turn up or down: how many steps a system may take on its own, how many tools it can call,\nand how often it must stop for a person. An AI agent is one system built with some of that\nautonomy, usually for one kind of task.\n\nThat framing helps when a proposal promises \"agentic AI\". Ask how much autonomy, over which\nactions, with what limits. A system that drafts and waits for approval is agentic in a small\nway, and often that is the right amount.\n\n## Where each one fails\n\nBoth fail. They fail differently, and the difference decides how much protection you need.\n\n**Chatbots fail in what they say.** They can state something false with confidence, answer\nfrom an outdated document, or answer a question they should have handed to a person. These\nfailures are real, but they pass through a reader first, and the fixes are about content and\nscope: better sources, clear limits on what it answers, and an easy route to a human.\n\n**Agents fail in what they do.** The same false belief, inside an agent, becomes a cancelled\norder or an email to the wrong customer. Two risks matter most, and both appear in the OWASP\nTop 10 for LLM Applications 2025:\n\n- **Prompt injection**, where text the system reads changes how it behaves. The indirect form\n  is the one that matters for agents: instructions hidden in a web page, a document or an\n  incoming email that the agent processes as part of its task\n  ([OWASP, LLM01:2025 Prompt Injection](https:\u002F\u002Fgenai.owasp.org\u002Fllmrisk\u002Fllm01-prompt-injection\u002F)).\n  A chatbot that reads a poisoned email may give a strange answer. An agent that reads it may\n  follow it.\n- **Excessive agency**, where a system can take damaging actions because it has more\n  functionality, permissions or autonomy than its task needs. OWASP's recommended defences\n  include giving it the fewest tools possible, the least privilege, acting in the user's own\n  context, enforcing authorisation in the downstream systems rather than trusting the model,\n  and requiring a person's approval for high-impact actions\n  ([OWASP, LLM06:2025 Excessive Agency](https:\u002F\u002Fgenai.owasp.org\u002Fllmrisk\u002Fllm062025-excessive-agency\u002F)).\n\nOctober is Cybersecurity Awareness Month in the US\n([CISA](https:\u002F\u002Fwww.cisa.gov\u002Fcybersecurity-awareness-month)), and agents are a good reason to\nadd AI systems to the review: an agent is another account with access to your systems, and it\nreads untrusted text for a living.\n\n## What an agent really costs: control\n\nAn agent's model calls are rarely its biggest cost. The work that makes one safe to run is:\nscoped credentials for every tool, approval steps for actions that matter, limits on how much\nit can do in a period, a log of every action with the reasoning behind it, a way to undo what\nit did, and a test set that is re-run whenever the prompt or the model changes.\n\nA chatbot needs some of this too, mostly around sources and scope. An agent needs all of it,\nand needs it before the first real task rather than after the first incident. When comparing\nthe two, compare the full cost of running each one safely, not what each can do in a demo. If\npeople will review an agent's work, [designing that review step](\u002Fblog\u002Fhuman-review-queues-for-ai-workflows)\nis part of the build, and so is [what any AI feature needs before it ships](\u002Fblog\u002Fwhat-an-ai-feature-needs-before-it-ships).\n\n## AI agent or chatbot: how to decide which you need\n\nFour questions settle most cases:\n\n1. **Does the job end in an answer or an action?** If someone needs information to decide, a\n   chatbot is enough, and adding actions only adds risk.\n2. **Can the action be undone?** Drafting, tagging and scheduling are cheap to reverse.\n   Payments, deletions and messages to customers are not. Irreversible actions stay with a\n   person, or wait for one.\n3. **How varied are the requests?** If the steps are the same every time, ordinary software or\n   a rules engine will do it more cheaply and predictably than either.\n   [Whether a task needs AI at all](\u002Fblog\u002Fai-agent-rules-engine-or-conventional-software) is\n   worth settling before choosing between these two.\n4. **Who answers for the result?** Someone has to own each action an agent takes. If nobody can\n   be named, the action is not ready to be automated.\n\nSome illustrative cases, to show how the questions play out:\n\n| Job | Fits | Why |\n|---|---|---|\n| Answering customers' questions about delivery times and returns | Chatbot | The job ends in an answer, and the customer acts on it |\n| Preparing a refund for a support agent to approve | Assistant | Action prepared by AI, confirmed by a person |\n| Tagging and routing incoming support tickets | Agent | Narrow, high volume, easy to correct if a tag is wrong |\n| Rescheduling appointments after a closure | Assistant, then agent | Start with approval; automate once the logs show it is reliable |\n| Issuing refunds or changing prices on its own | Neither, yet | Irreversible and costly to get wrong; keep a person in the decision |\n\n## Start smaller than you think\n\nThe safest route to an agent usually starts as a chatbot. Let it answer, then let it prepare\nactions for a person to confirm, then hand it one action at a time, read-only before write,\nreversible before irreversible, each with its own permission and log. You learn what it gets\nwrong while the cost of a mistake is still a sentence, and every new action has evidence behind\nit rather than a promise.\n\nIf you have a process where you are weighing a chatbot against an agent, explore AI and\nautomation with us: we will look at where the job really ends, which actions are safe to hand\nover, and what it would take to run them under control.
