The Personal Assistant
A regular chatbot: You ask, it answers. That's it.
An AI Agent: You give a goal, it figures out the steps AND does them!
You: "Book me a flight to Tokyo next week under $800"
Agent:
1. Searches flight sites
2. Compares prices
3. Finds a good option
4. Books it for you!
The Difference
Chatbot (LLM): "Here are steps to book a flight..."
Agent: Actually books the flight
Agents can:
- Use tools (search, email, code)
- Make decisions
- Complete multi-step tasks
- Take real actions
How They Work
Goal → Plan steps → Execute each step →
Observe results → Adjust → Repeat until done
The AI thinks: "What should I do next to achieve this goal?"
Examples
- Coding agents: Write AND run code
- Research agents: Search, read, summarize
- Task agents: Manage calendars, send emails
In One Sentence
AI agents are autonomous assistants that don't just answer questions—they take actions to complete tasks for you.
