AI Agent Examples: 16 Real-World Use Cases

AI agents are systems that can reason, use tools, and take actions on a user’s behalf. Unlike chatbots that only answer questions, agents pull data from multiple systems, maintain context, and complete tasks that go beyond a single prompt.

Not all AI agents behave the same. Some respond to one request at a time, while others remember context, plan multi-step workflows, or operate with deep, industry-specific expertise. Understanding these differences helps teams design agents that work in production environments instead of breaking under real-world conditions.

The AI agent examples below illustrate real-world use cases across industries, demonstrating how each type operates and what it depends on to remain reliable.

What Types of AI Agents Are There?

AI agents fall into five categories based on their capabilities:

1. Reactive agents: Respond to individual requests without memory of past interactions.
2. Memory-based agents: Store context across sessions, enabling continuity and personalization over time.
3. Contextual and tool-using agents: Combine LLM reasoning with API calls to synthesize data and take actions across multiple systems.
4. Autonomous multi-step agents: Plan, execute, and iterate on complex workflows without requiring human prompts at each step.
5. Vertical industry-specific agents: Add deep domain expertise and integrate with specialized tools in environments like healthcare, finance, legal, and manufacturing.

What Are Examples of Reactive AI Agents?

Reactive AI agents respond to each request in isolation, without retaining memory or carrying context between interactions. The following AI agent examples show how this model works in single-step workflows.

1. FAQ and Knowledge Response Bots

These agents answer user questions by retrieving information from predefined knowledge bases. A customer asks about return policies, the agent searches indexed documentation, finds the relevant section, and generates a response. 

The agent has no awareness of what the same customer asked yesterday. Each question gets treated as an independent retrieval task.

Use case: 

Shopify uses AI agents to handle merchant questions about platform features. It pulls answers from help center articles and product documentation to resolve common inquiries without human support intervention.

2. Basic Support Deflection Agents

Support deflection agents triage incoming requests and route tickets without multi-step reasoning. A customer submits a complaint, the agent classifies the issue type, determines urgency, and assigns it to the appropriate queue. 

These agents need access to routing rules, classification taxonomies, and historical ticket data to improve classification accuracy.

Use case: 

Zendesk's intelligent triage categorizes incoming tickets by intent, language, and sentiment. It routes billing issues to finance teams and technical problems to engineering support without manual sorting.

3. Simple Data Lookup Agents

Lookup agents fetch information from a single system. When an employee requests their remaining PTO balance, the agent queries the HR system and returns the balance. 

The data requirements seem minimal, but authentication adds complexity. The agent needs secure access with credentials that respect user permissions, otherwise an employee asking about their own PTO balance could accidentally see someone else's records.

Use case: 

Bank of America's Erica assistant lets customers ask natural language questions about their balance and spending, then pulls the relevant data from their account to respond. The assistant delivers instant answers inside the banking app.

What Are Examples of Memory-Based AI Agents?

Memory-based AI agents store context across sessions and workflows. They remember what happened in previous interactions and use that history to inform current decisions. Here are some examples:

4. Personal Task Assistants

Personal assistants track tasks, preferences, and ongoing projects for individual users. The assistant remembers the preference for morning meetings, knows the quarterly report is due Friday, and flags that the user needs to follow up with a client. 

The agent needs user-specific memory and integrations with calendars, email, and task tools. That raises privacy concerns because the memory stores sensitive personal data for each user.

Use case: 

Microsoft Copilot in Outlook learns individual communication patterns, drafts contextual email replies based on past conversations, and suggests meeting times based on calendar availability and historical preferences.

5. Multi-Session Customer Support Agents

Multi-session support agents recall previous conversations. When a customer reaches out, the agent knows they already contacted support last month about the same integration issue and that the previous resolution failed. 

To do this safely, the agent must store conversation history tied to individual users, with access controls that ensure each session only surfaces data from the current customer.

Use case:

Intercom's AI agent maintains conversation context across sessions and recognizes returning customers. It references previous issues, so customers don’t have to repeat themselves.

6. Research Agents With Knowledge Persistence

Research agents working on extended projects need to remember what they have already found. When analyzing a market over several days, the agent should build on previous findings, identify knowledge gaps, and focus on unanswered questions. 

The memory architecture includes the facts discovered, sources consulted, and conclusions drawn.

Use case:

Claude's Projects feature lets users upload research documents and maintain context across conversations, so the agent builds on previous analysis rather than starting fresh each session.

What Are Examples of Contextual and Tool-Using AI Agents?

Contextual AI agents combine LLM reasoning with the ability to call external tools and APIs. Besides retrieving information, they take actions, synthesize data from multiple sources, and produce outputs. The following use cases show how this works in practice.

7. Customer Support Resolution Agents

Resolution agents solve customer issues end-to-end. When a customer reports a billing problem, the agent pulls ticket history, retrieves CRM details, checks invoices, reviews policies, and drafts a reply. 

The challenge is that systems use different auth methods, APIs, and rate limits while agents require fresh data. This makes custom integrations slow to build and difficult to scale.

Use case: 

Klarna's AI assistant handles customer service chats. It resolves refund requests and payment disputes by accessing order history, payment records, and merchant policies.

8. Sales Research and Personalization Agents

Sales agents research prospects and generate personalized outreach. Before contacting a lead, the agent queries the CRM for past interactions, pulls email threads, checks LinkedIn activity, reviews website visit logs, and synthesizes everything into a briefing or personalized email.

These agents depend on data freshness to prevent generic outreach that prospects ignore.

Use case: 

Salesforce’s Einstein analyzes prospect engagement across emails, website activity, and CRM data to score leads and generate personalized talking points. This helps sales reps prioritize outreach based on buying signals.

9. Operations and IT Assistants

IT operations agents diagnose and resolve infrastructure issues. When an alert fires, the agent reads log files, fetches configuration details, queries monitoring dashboards, correlates with past incidents, and proposes a fix. 

To work effectively, the agent needs access to system records and log data. Its permissions must satisfy security teams while still allowing investigation and action.

Use case: 

Datadog's Bits AI investigates alerts by correlating logs, traces, and metrics across the infrastructure, then surfaces root causes and suggests remediation steps based on patterns from past incidents.

What Are Examples of Autonomous Multi-Step AI Agents?

Autonomous AI agents plan, verify, and iterate without requiring human prompts at each step. They receive a high-level objective and figure out how to accomplish it. Real-world deployments show how these agents operate in practice:

10. Workflow Orchestration Agents

Orchestration agents decompose complex objectives into subtasks and coordinate execution. When asked to onboard a new employee, the agent creates accounts across systems, provisions hardware, schedules orientation, assigns training, and notifies team members. 

These agents need both read and write access across enterprise systems and must handle failures when something breaks mid-workflow.

Use case:

Workday's orchestration capabilities automate employee lifecycle workflows across HR systems, IT provisioning, and payroll. They coordinate complex processes, such as promotions, across multiple departments simultaneously.

11. Analysis and Reporting Agents

Reporting agents pull data from multiple tools, perform analysis, and produce formatted outputs. A weekly business review agent queries revenue data from billing, pipeline information from CRM, satisfaction scores from support, and usage metrics from analytics. 

The agent compares results against targets, identifies trends, and generates a report.

Use case: 

Tableau's AI features turn dashboard data into clear narratives, pulling insights from multiple data sources to create executive briefings that would take analysts hours to put together.

12. Data Cleanup and Reconciliation Agents

Reconciliation agents identify mismatches between systems and propose corrections. When customer records in CRM do not match billing data, the agent flags discrepancies, determines which source is authoritative, and either corrects the error or queues it for human review. 

The infrastructure requires ongoing access to multiple sources with the ability to detect changes since the last run, using change data capture or incremental sync.

Use case: 

Stripe’s Revenue Recognition reconciles payment data against invoices and accounting records. It flags mismatches and proposes adjustments for the finance team review.

What Are Examples of Vertical AI Agents?

Vertical AI agents combine deep domain expertise with integrations into industry-specific tools and data formats. They operate in regulated environments where teams must prioritize accuracy, auditability, and compliance. Here are some examples:

13. Healthcare Documentation Agents

Healthcare documentation agents transform clinical conversations into structured medical notes. A physician speaks during a patient encounter, and the agent captures symptoms, diagnoses, treatment plans, and follow-up instructions. 

The output conforms to required documentation standards and integrates with electronic health record systems.

Use case: 

Nuance DAX Copilot listens to physician-patient conversations and generates clinical documentation in Epic and other EHR systems. This reduces documentation time while maintaining compliance standards.

14. Financial Monitoring and Reconciliation Agents

Financial agents monitor cash positions across accounts, flag unexpected movements, and reconcile transactions. Data sovereignty matters since many institutions cannot send transaction data to third-party cloud infrastructure. 

The agent needs access to banking feeds, ERP systems, and market data. It operates within controlled environments that meet SOC 2 and PCI compliance requirements.

Use case:

Ramp’s AI monitors company spending as transactions happen and flags unusual activity. It also automates expense coding and reconciliation workflows within a PCI-compliant infrastructure.

15. Legal Contract Review Agents

Contract review agents analyze legal documents to flag risks, extract obligations, and compare clause variants against standard language. 

When a new vendor contract arrives, the agent flags unusual liability provisions and highlights deviations from approved templates. It also extracts key dates and financial terms, producing a summary that speeds up legal review.

Use case:

Ironclad's AI reviews contracts against company playbooks, flags non-standard terms, and suggests approved fallback language. This reduces legal review cycles from days to hours.

16. Manufacturing Predictive Maintenance Agents

Predictive maintenance agents interpret sensor data from equipment, forecast potential failures, and recommend maintenance actions before unplanned downtime occurs. 

These agents process sensor data and integrate with manufacturing execution systems to plan maintenance at the right time. Because many factories restrict internet access to operational technology, teams often run them in air-gapped environments.

Use case:

Rockwell Automation's FactoryTalk Analytics GuardianAI monitors equipment using sensor data from variable frequency drives and detects anomalies linked to likely failure causes. This gives maintenance teams time to schedule repairs before unplanned downtime occurs. The software analyzes data locally without requiring cloud connectivity.

Frequently Asked Questions

What types of AI agents benefit most from context engineering infrastructure?

All AI agents benefit, but contextual tool-using agents and autonomous multi-step agents see the biggest gains. These agents pull data from multiple systems, require fresh information, and need permission-aware retrieval. Without proper infrastructure, teams spend weeks building custom integrations instead of improving agent behavior.

Why do AI agents fail in production?

Most failures trace back to data access problems. Agents work with stale information because pipelines break overnight. They expose sensitive data because permission models were never implemented, and they hallucinate because the right context never reached the model. Fixing the data foundation fixes most production failures.

How do row-level permissions affect AI agent performance?

Agents without permission-aware retrieval risk exposing data users should not see. A support agent answering customer questions might accidentally surface another customer's records. Row-level and user-level access controls scope every retrieval to what the current user can access, keeping agents compliant without custom security code.

What makes multi-system data access difficult for AI agents?

Each SaaS tool uses different authentication methods, API structures, rate limits, and schemas. Building custom scripts for Notion, Slack, and Google Drive means handling OAuth flows, token refresh, and format normalization separately for each one. When vendors change their APIs, those scripts break and agents stop working until someone fixes them.
