What is an AI agent, and what can it actually do?
A practical explanation of AI agents, how they differ from chatbots, and which jobs are suitable for automation.
An AI agent is software that can understand an instruction, use approved tools and carry out a sequence of steps toward an outcome. The useful distinction is not how intelligent it sounds. It is whether it can safely complete work.
Agent versus chatbot
A chatbot mainly responds inside a conversation. An agent can also act outside that conversation, such as checking a calendar, updating a record, searching approved sources or preparing a document.
The boundary matters. A good agent is not given unlimited access. It receives only the tools, data and permissions required for its agreed role.
The five parts of a useful agent
- A clear role and measurable outcome.
- Instructions covering priorities, tone and boundaries.
- A suitable AI model for the difficulty and cost of the work.
- Approved tools and integrations, such as Telegram, email or a CRM.
- Human approval for actions that are sensitive, expensive or difficult to reverse.
Good first jobs
Start with work that is repeated, time-consuming and easy to verify. The best first agent usually handles one defined job well rather than attempting to run an entire business.
- Summarising an inbox and preparing follow-ups.
- Producing a daily plan from calendars and task lists.
- Qualifying enquiries before a person responds.
- Preparing regular reports from structured data.
- Researching a topic and returning a sourced briefing.
Jobs that still need a person
High-impact medical, legal, financial, employment and safety decisions require qualified human judgment. Agents can help organise information, but they should not become the sole decision-maker.
A sensible way to begin
Choose one outcome, define the information the agent may access, decide which actions require approval and test the workflow with realistic examples. Expand its responsibilities only after the first workflow is dependable.
