Full explanation
An AI agent is more than a chatbot. It can take a goal, break it into steps, use tools (browsers, APIs, files), and deliver a result with little supervision.
Agents can write code, send emails, generate marketing posts, analyze data, or build full products. You give them a mission and the right tools, and they get to work.
For a founder, agents are like a remote team that never sleeps. The cost is much lower than hiring, and you can scale work up or down at any time.
Concrete example
You ask an AI agent to find 50 potential customers, write each of them a personalized email, and put the results in a spreadsheet. It takes 20 minutes instead of 2 days.
