AI agent
AY-eye AY-jent
An AI system that can plan, reason, and take autonomous actions to complete tasks. Goes beyond chat to actually do things.
An AI agent is a system that does not just answer questions. It takes actions. It plans. It reasons through multi-step problems. It calls APIs, writes code, searches the web, and executes workflows. A chatbot waits for you to ask a question. An agent goes and does the work.
The distinction matters for marketers because agents change how software gets discovered and purchased. A developer does not browse your pricing page. An agent evaluates your API documentation, checks your rate limits, compares your pricing to competitors, and makes a recommendation. The agent is the new buyer. Your website needs to be readable by machines, not just humans. This shift is what agentic commerce describes.
GitHub Copilot started as autocomplete. Now it is an agent that can plan a code change across multiple files, run tests, and open a pull request. Cursor's agent mode lets you describe a feature in natural language and watches the AI implement it. The trajectory is clear. Agents will do more. Humans will supervise more.
Examples
A developer uses an AI agent to build a feature.
A developer types "Add Stripe payment processing to the checkout page" into Cursor's agent mode. The agent reads the codebase, installs the Stripe SDK, creates the payment form component, adds the API route, and runs the tests. The developer reviews the diff.
An AI agent handles DevOps tasks.
An on-call engineer gets a 3 AM alert about high latency. An AI agent triages the alert, checks recent deployments, identifies a bad database query, suggests a fix, and drafts the rollback PR. The engineer reviews and approves instead of debugging from scratch.
An agent evaluates software for procurement.
A procurement agent compares three API providers. It reads their documentation, tests their endpoints, benchmarks response times, and calculates cost per request at projected volume. It delivers a comparison table. No human visited a single website.
