The big idea
An AI agent runs a loop: read what is happening, plan a step, do the step, check the result, then repeat until done.
Some examples
- Like a robot vacuum: see, decide, move, check, repeat.
- Like a chef: read recipe, do step, taste, fix, continue.
- AI agents do this with code and web pages instead of food.
- The loop is what makes it an 'agent' instead of just chat.
Try it!
Watch a robot vacuum at home or online. Notice the read-decide-move loop. AI agents work the same way.
