What Is Agentic AI?
Agentic AI is a type of AI system that can receive a goal and work toward completing it by planning steps, choosing tools, executing actions, and checking its own results.
What Is Agentic AI?
Agentic AI refers to AI systems that can act with some degree of autonomy to complete goals.
A traditional AI tool responds to your input and gives you an answer. An agentic AI system goes further: it receives a goal, decides what to do next, takes an action, checks the result, and continues until the goal is finished.
The key word is 'agent'. In everyday language, an agent is someone who acts on behalf of someone else. A travel agent books flights for you. A real estate agent finds you a property.
An AI agent works the same way: you give it a goal, and it acts on your behalf to complete it.
Simple comparison:
Traditional AI: You ask, it answers.
Agentic AI: You give a goal, it plans, acts, and delivers a result.
Two Different Workflows
Generative AI workflow:
User sends request
AI model generates content
Result is returned
Agentic AI workflow:
User provides goal
Agent understands the goal
Agent creates a plan
Agent selects a tool
Agent executes an action
Agent observes the result
Agent updates its state
Agent continues or finishes
The second workflow is what this course teaches. The agent does not just generate text. It takes real actions in the real world.
Everyday Agentic AI Examples
- Customer support agent: receives a complaint, looks up the account, checks order history, issues a refund, and sends a confirmation email automatically
- Research agent: receives a topic, searches multiple sources, collects results, summarises findings, and delivers a structured report
- IT support agent: detects a server alert, runs diagnostics, applies a known fix, and escalates to a human if the fix does not work
- Scheduling agent: receives a meeting request, checks calendars, finds a free slot, sends invites, and confirms attendance
- Software agent: receives a bug report, reads the codebase, identifies the cause, proposes a fix, and creates a pull request for review
