When you use ChatGPT for the first time, you may be surprised by its response speed, language capabilities, and amount of information. It is like an all-knowing and all-powerful online encyclopedia assistant that can write articles, modify resumes, generate marketing copy, and even write a piece of code. For many people, such tools are enough to change their work habits and lifestyle.
But if you are an entrepreneur, PM or freelancer, you will soon find that although ChatGPT can help you "make things", it cannot "complete the task". You have to direct every step yourself, as if you were working with a very smart but passive assistant. At this time, the concept of AI Agent emerged.
AI Agent is not a simple chatbot, but an intelligent system that can actively understand goals, plan task processes, and perform multi-step actions. You just need to tell it "I want to increase the conversion rate of the website", and it will automatically help you analyze website problems, make copywriting suggestions, perform A/B testing, and finally report the results. Such capabilities not only subvert our expectations of AI, but also mark the starting point for the next wave of AI revolution.
Today’s article will take you from the most basic definition to an in-depth understanding of what AI Agent is, what it can do, what are the representative tools and frameworks, and why it is the new trend that deserves your attention after ChatGPT. Let’s read on!

When a small or medium-sized enterprise begins to expand, the first problem it faces is usually not the market or product, but a lack of staff. Imagine that you are the person in charge of this company today. You may need to perform three duties: replying to customers, writing copy, and handling customer reviews at the same time.
And in the midst of these tedious but important tasks, you start hearing about a new helper that could change the way you do your job: Artificial Intelligence, or more specifically: Large Language Models (LLMs).
