AI agent examples
Eight practical AI agent examples for service, research, documents, sales, marketing and operations—with permissions, safety and measurement guidance.
An agent is different from a simple chatbot when it can act on systems or information rather than only produce a reply. Because actions create risk, strong implementations define permissions, review points, logs and clear fallback paths.
1. Customer service triage agent
The agent classifies incoming requests, retrieves approved account or knowledge-base information, drafts a response and routes sensitive or unusual cases to a person. It should not make unsupported promises or expose information from another customer.
2. Research and monitoring agent
A research agent can watch selected sources, extract changes, compare claims and produce a cited summary. Useful controls include an approved source list, freshness requirements, quotation limits and human review before external publication.
3. Document processing agent
This agent reads invoices, forms or contracts, extracts defined fields, validates them against rules and sends exceptions for review. It is most valuable when the workflow includes repeatable checks and a reliable system of record.
4. Sales preparation agent
An agent can combine CRM notes, public company information and past interactions into a concise meeting brief. It may suggest questions or next steps, while the salesperson verifies the information and controls communication.
5. Marketing operations agent
The agent can organise a campaign brief, generate channel adaptations, check links and naming, and prepare draft assets. Brand, legal and factual review should remain explicit before anything is published or spending is activated.
6. Website quality agent
A website agent can crawl approved pages, flag broken links, missing metadata, accessibility issues or content changes, and create a prioritised report. Automatically changing a live site requires stronger permissions and rollback than monitoring it.
7. Internal knowledge agent
Connected to approved company documents, an agent can answer policy or process questions with citations. Access must follow user permissions so retrieval does not reveal documents the requester could not otherwise open.
8. Workflow coordination agent
An agent can monitor task states, request missing information, update records and alert an owner when a deadline or dependency is at risk. It should make routine, reversible updates and escalate ambiguous decisions.
How to choose a good AI-agent use case
- The goal and success criteria can be defined.
- The process has repeatable steps but still benefits from language or judgment.
- Required data and tools can be permissioned safely.
- Errors are detectable and recoverable.
- A human owner can review important outcomes.
- The time or quality benefit is worth operating and monitoring the system.
Agent, automation or chatbot?
Use normal automation for fixed, predictable rules. Use a chatbot when the primary job is conversation or retrieval. Consider an agent when the system must plan across changing inputs and choose from several approved actions. More autonomy is not automatically better.
Safety and governance checklist
- Give the minimum tool and data permissions required.
- Separate drafting from irreversible or public actions.
- Require confirmation for payments, deletion, publication and sensitive communication.
- Log sources, actions, tool results and responsible owners.
- Test prompt injection, bad data and unavailable-tool scenarios.
- Provide a clear stop, rollback and human-escalation path.
- Monitor quality, cost, latency and real business outcomes after launch.
How to measure an AI agent
Measure task completion, accuracy, escalation quality, time saved, cost per successful outcome and error severity. Include user trust and operational burden. A fast agent that creates hidden correction work is not successful.
Frequently asked questions
Do AI agents work without humans?
They can handle bounded tasks independently, but accountable owners and review paths remain important, especially for sensitive or external actions.
Can an AI agent use business software?
Yes, when the software offers an approved interface and permissions are limited appropriately. Every integration expands the security and reliability surface.
Where should a company start?
Start with one high-volume, low-risk workflow that has clear inputs and measurable outcomes. Run it in assistive mode before increasing autonomy.
