A chat window does not determine which one you have: an agent can be presented as a chatbot, and a chatbot can use tools without controlling a broader workflow.
What is the difference between an AI chatbot and an AI agent?
The useful distinction is who controls the work. A chatbot typically responds to a prompt with an answer, draft, summary, or idea. An agent uses a model to help decide how to pursue a goal: which step to take, whether to use a tool, and what to do after seeing the result.

OpenAI draws the line at workflow control: an application that uses a language model but does not use it to control workflow execution—such as a simple chatbot or single-turn application—is not an agent under its definition. Anthropic similarly distinguishes fixed workflows, whose paths are predefined in code, from agents, in which the model dynamically directs the process and tool use. See OpenAI’s practical guide to building AI agents and Anthropic’s guide to building effective agents.

These are design patterns, not universal product categories. Vendors may use the word “agent” differently, and real systems can mix conversational responses, fixed steps, and model-directed decisions.
#1 Best Overall
How the three approaches compare
| Dimension | Chatbot or single-turn app | AI agent | Fixed workflow |
|---|---|---|---|
| Who directs the steps? | Usually the user prompts; the system responds. | The model may choose the next step based on the task and what it observes. | Code specifies the steps and paths in advance. |
| Typical fit | One-off answers, drafting, brainstorming, or exploration. | Multi-step goals that require decisions or adaptation. | Stable, well-defined processes where consistency matters. |
| Tool use | May be absent or limited. | Can select tools to gather information or take authorized actions. | Tools and actions are prescribed by the workflow. |
| Adapting to results | Usually responds within the current interaction. | Can inspect results and change its approach. | Changes generally require changing the defined logic. |
| Oversight | A person evaluates the response and decides what to do. | Guardrails and human check-ins can bound execution. | Prescribed paths make behavior easier to anticipate. |
| Main tradeoff | Direct and simple for conversational tasks. | More flexible, but may add cost, latency, and complexity. | Predictable for clearly specified work, but less adaptable. |
These are tendencies rather than guarantees. Tool access by itself does not make an application agentic: the important question is whether the model directs execution, rather than merely invoking a predetermined capability.
What does an AI agent do that a chatbot usually does not?
An agent can work through a loop: plan a step, act, observe what happened, and adjust or continue. It may select among approved tools as the state of the task changes, then stop when it has completed the work or needs a person’s input. Anthropic describes this plan–act–observe–adjust pattern in Trustworthy agents in practice.
Rank #2
For example, a chatbot can explain how to prepare a report. An agentic system could retrieve information from approved sources, draft the report in a required format, check for missing fields, and then hand the draft to a person or take another authorized step. This illustrates a possible design; it is not a claim about what any particular product can do.
“Agent” does not mean unlimited or reliably independent. Its behavior remains bounded by its instructions, available tools, and safeguards. A well-designed system can pause, ask for clarification, or hand control to a human instead of proceeding.
How can you tell whether a product is really agentic?
Look at observable behavior rather than the label. Ask:
- Does the system only generate a response, or does it control a sequence of steps toward a goal?
- Can it decide which step or tool to use next, or are those choices fixed in advance?
- Does it inspect tool results and adjust what it does?
- Which actions can it take, and are they limited to approved tools and permissions?
- When does it pause or return control to a person?
A product may combine patterns: for instance, a fixed workflow can include a chatbot, or an agent can present its progress through a chat interface. The presence of a conversation is not proof either way.
Rank #4
When should you use a chatbot, a fixed workflow, or an agent?
Choose chat for one-off or open-ended work
Use a conversational system for tasks such as brainstorming, exploratory writing, or asking for an explanation when a person can review the answer and decide what happens next. OpenAI Academy likewise describes regular chat as often better suited to open-ended thinking and one-off tasks in its Workspace agents overview.
Choose a fixed workflow when the process should stay consistent
When a task is well-defined and the same sequence should run each time, a prescribed workflow can make behavior more predictable. If the process changes, the workflow logic can be updated deliberately rather than asking a model to improvise each step.
Consider an agent when the task needs flexible, multi-step decisions
An agent may be appropriate when a goal involves selecting tools, responding to changing results, or deciding what step comes next. Its flexibility is worthwhile only if it solves a real need; additional model-directed steps can bring more complexity, latency, and cost than a simpler approach.
Bound consequential actions
For any system that can affect other tools or records, define what it may do, what requires approval, and when it must stop for a person. OpenAI’s guide discusses guardrails and halting or transferring control; Anthropic’s account also describes checking in for human input. The level of oversight should fit the consequences of an incorrect action.
