What is AI Agent?
An autonomous software system that perceives its environment, makes decisions, and takes actions to achieve goals without continuous human direction.
Detailed Explanation
An AI agent is a software entity that uses artificial intelligence to perceive its environment through sensors (APIs, browsers, files), process information using language models or other AI techniques, and act upon that environment through effectors (code execution, API calls, browser automation). Unlike traditional software that follows rigid instructions, AI agents can adapt their behavior based on context, learn from outcomes, and pursue open-ended goals. Agents range from simple task executors to complex systems with persistent memory, tool use, and hierarchical planning.

Frequently Asked Questions
What is the difference between an AI agent and a chatbot?
A chatbot responds to individual messages in isolation. An AI agent maintains state across sessions, uses tools to interact with external systems, and pursues multi-step goals autonomously.
Can AI agents replace human workers?
AI agents augment human capabilities rather than replace them. They excel at repetitive, data-intensive tasks but require human oversight for strategic decisions, creative work, and ethical judgment.
What makes an agent 'autonomous'?
Autonomy means the agent can set sub-goals, select tools, handle errors, and adapt its approach without waiting for human approval at every step. The degree of autonomy varies by implementation and safety constraints.
