What is an AI Tool? The Simple Guide to LLMs & AI Tools (2026)

Many people wonder what an AI tool is. While many people assume that they are complex software, they really are simple. Grasping what they are will cement your place among the greats who will take advantage of the great AI revolution that began several years ago. We now recognize that grasping artificial intelligence including its tools is what will separate the haves and the have-nots in the near future.

The internet courtesy of the burst in AI technologies has seen many people coining different terms for defining AI tools. While these definitions are useful, they tend to miss the mark in help the every-day internet use fully understand the fuss about artificial intelligence. This post breaks down AI tools in a way that is easy to understand.

In long-form an AI tool is an Artificial Intelligence Tool. Therefore, an AI tool is a structure or program that harnesses a large language model to craft or design desired solutions. This therefore brings us to defining what a large language model is. A large language model (LLM) refers to software that accepts instructions from humans or computers and provides output in the form of the natural language that you and I speak. Let’s paint a picture that will help you to understand what an AI tool is and how it relates to a large language model (LLM).

Imagine fishing in an ocean using a canoe or boat and a fishing rod. The ocean, in this case, is akin to a large language model, while the fishing rod is akin to the artificial intelligence (AI) tool. Using this imagination, the ocean comprises of so many resources including different types of fish. The ocean, just like the large language model, is a resource, which when utilized using an artificial intelligence tool (fishing rod), provides useful output or food resources. One would use the fishing rod to capture the fish in the same way one would utilize an Artificial intelligence tool to create pre-determined results. This analogy helps us understand what an AI tool is and its relationship to a large language model. Let us proceed to the next section where we elaborate some popular examples of AI Tools.

Examples of AI Tools

Based on the above analogy, it comes without saying that there are different types of AI tools with their own unique strengths and weaknesses. For example, ChatGPT understands human language and gives output in the form of natural language. To this concept, one can key in a question in ChatGPT and it will provide an output in a manner similar to what we have on different search engines like Google, Yahoo Search, and so much more. This section breaks down the popular examples of AI tools to introduce your mind to popular AI tools.
