An AI agent is a software system that can pursue a goal and complete complex, multi-step tasks on its own.

The Key Difference: Autonomy

AI agents have a higher degree of autonomy than traditional bots or AI assistants.

• A Bot simply follows pre-defined rules.
• An Assistant helps a user with a task by responding to requests.
• An Agent, however, can make decisions, plan, and take action independently to achieve a goal.

This ability to handle complex workflows that involve multiple systems and decisions is the core value of AI agents.

Why We Need AI Agents

The limitations of traditional automation created the need for a more intelligent, autonomous system. The AI agent, with its ability to plan and use tools, is designed to solve this exact problem.

Core Capabilities of an AI Agent

An AI agent has several core capabilities that allow it to function autonomously:

• Planning: The ability to break a large goal into smaller, actionable steps.
• Tool Use: Connecting to software, APIs, or databases to perform actions (e.g., sending an email, updating a database).
• Memory: Retaining information from previous steps to maintain context across multiple interactions.
• Reflection: Evaluating its own performance and correcting errors.

Real-World Applications

These capabilities allow AI agents to automate complex workflows across a variety of business functions.

• In IT Support: Troubleshoot technical issues, handle password resets, and process software requests.
• For Human Resources: Screen candidates, schedule interviews, and onboard new hires across multiple systems.
• In Finance: Approve expenses, generate reports, and assist with fraud detection.
