It Depends
Every Nigerian business owner is asking the same question right now: do I need an AI agent, or just an AI tool?
Well, it depends.
How comfortable are you giving an AI a goal like this: ‘Make me the most money you can, selling my product to Nigerians through our website, social media, and email.’ And then letting AI go and do it however it thinks best?
Or would you rather tell AI what to do and how to do it?
If yes to the first, you need an AI agent. If yes to the second, you will be more comfortable with a tool. Because that is the key difference between an AI agent and an AI tool.
Agency. Autonomy. Trust.
Most of us, me included, are not that comfortable giving up our autonomy to anyone, even our spouse, not to talk of a piece of computer code, most likely written by someone else.
Before we can say definitively what a Nigerian business needs, let’s define what an agent is.
What Is An Agent
An agent is a piece of software, that you give a goal and the agent decides what to do to achieve it and does it, without you spelling out how the agent should achieve the goal. If you tell it how to achieve the goal, then the software is a tool not an agent.
For a piece of code to be called an agent, the following three things have to be true:
- The software receives a goal not a task. You tell it what outcome you want but not how to get there.
- An agent decides what steps to take. It chooses the tools and the steps to take, but it adjusts based on the results it sees.
- An agent acts. It doesn’t just suggest. It does. It sends emails, updates databases, navigates websites, calls APIs, responds to customers, and manages your inbox.
Let’s take a real world analogy so we can understand the distinction better. Imagine a chef and a recipe. If you give the chef your grandmother’s recipe for amala abula, and he makes it exactly using the recipe, that’s automation and your chef is simply a tool. No offence to our imaginary chef.
However, if you tell the chef, make me amala abula the way they used to make it in Abeokuta in the old days. And the chef goes off and makes it however he thinks the old Abeokuta way was, the chef has graduated and become an agent.
For an agent to work, it has to be able to do all of the following:
- Tool Use: It is able to use the tools at its disposal like call APIs, browse the web, query databases, send messages.
- Planning: It can break a goal into a series of multiple steps. So, book my flight to Abuja for Friday, becomes: search flights → compare options → check my calendar → pick the best option → confirm with me → book → save confirmation.
- Memory: It remembers past interactions. For example, it remembers you prefer morning flights, because an agent builds context over time.
- Self-correction: When something fails, it tries something else. If the flight booking site is down, it checks for an alternative site. An agent doesn’t just stop. It adjusts.
Sounds like the perfect assistant? Yes and no.
Agents in 2026 are real but imperfect. They are powerful and can be useful. But they are not infallible. They do get stuck. They still hallucinate. They sometimes make the wrong decisions. You are still responsible for final decisions because the buck does stop with you.
How It All Started
In 1950, Alan Turing published a paper proposing that for an artificial system to be regarded as intelligent it needed to be able to act as a human would in any situation. And for about 50 years from 1950 to the 1990s, AI agents existed as an idea.
Almost everything we do or use today started as an idea.
The 1990s saw early intelligent agents in software, autopilot programs, basic e-commerce bots, that worked but were narrowly specified. The 2000s to 2010s saw the advent of deep learning which enabled AI agents to perform complex tasks such as image recognition, language translation and game-playing.
In March 2016, DeepMind’s AlphaGo program played Lee Sedol, one of the greatest Go players in history, in a five-game match in Seoul. AlphaGo won 4-1 while the world watched live. Go is an ancient Chinese board game and for many years it was considered the hardest game to program a computer to play. By contrast, Chess fell to a computer in 1997 when IBM’s Deep Blue beat Garry Kasparov, while Go held out for nearly 20 years until 2016.
What made AlphaGo historic was how it won. In game two, AlphaGo played a move that broke 3,000 years of Go theory. Human commentators thought it was a mistake but the move turned out to be brilliant. For the first time, AI was making decisions that surprised even its creators. That principle, give the system a goal and let it figure out how to achieve it, became the foundation of every AI agent we have today.
In 2017, Google introduced the transformer architecture which became the foundation for subsequent AI models like ChatGPT and Claude that we know today. The transformer architecture allowed machines to understand language well enough that we could tell them what to do in plain English. Up to this point our commands had to be translated to machine language for computers to understand us.
In November 2022, OpenAI released ChatGPT, the first large language model chatbot, to the public. But ChatGPT was still a chatbot you could only ask questions like write an email. It was not yet an agent you could tell to do things like send the email.
2023 brought Tool Use, where AI models could now call external tools, APIs, databases, web browsers. This finally allowed AI models to not only write emails but to also send them. Our Build page uses this capability because it calls the Claude API.
2025-2026 has seen AI agents become real products. From OpenAI’s Operator which could interact with websites to Google’s Project Mariner that browses the web for you. But still these agents were narrowly defined, intended to run in well-structured familiar environments.
In spite of the milestones in the development of AI agents, and there have been some real wins, it is worth noting that there have also been some disasters.
In July 2025, an AI agent on the Replit coding platform was directed to build a software application. Instead, it deleted an entire production database, apologised for it and then advised that the data could not be recovered. Thankfully, the developer ignored the agent, rolled back and got his data back.
Another example is McDonald’s experimenting with AI drive-thru orders. The AI couldn’t handle different accents, background noise, or customers who deliberately tried to break it. One famous TikTok video showed it adding 260 McNuggets to an order while the customers begged it to stop.
These failures do not take away from the many successes of AI agents. They just reinforce the principle that agents have to be designed properly by experienced developers with the appropriate level of autonomy to match the right kind of work.
What Do You Need
The critical difference between an AI tool and an AI agent is that an AI agent is a grown up AI tool.
An AI tool is a young child who still needs to hold mummy’s hand while an agent is a teenager who feels it is all grown up and doesn’t hold mummy’s hand. But mummy still has ultimate responsibility.
The progression from tool to agent is as follows:
- Pure Tool – Single shot input to output. No memory, no decisions. e.g. our Job Scam Checker where you paste in the job listing, the tool scans it and produces a risk rating score of how likely the job listing is to be a scam.
- Tool with Options – A pure tool with branching logic and user controls. e.g. a job scam checker with parameters like industry, job level, location and type of job, so it can give you a more accurate risk rating of the job listing.
- Workflow / Multi-step Tool – The tool has multiple steps in a fixed repeatable sequence. Basically, automation. You’ve used these many times even if you didn’t know what to call them. e.g. Nigerian customer service banking apps that pick up your calls and respond to you based on the options you select. These are called IVR systems, Interactive Voice Response, in the industry. You know them as ‘press 1 for English.’ When you need more sophisticated responses or a response that has not been preprogrammed, you have the option of speaking to a live representative.
- Agent – The system decides what steps to take based on the goal. Different inputs lead to different paths. Same inputs can lead to different paths too. Remember our Agent Chef. An agent would be a customer service app that can respond to you based on what you say or write without presenting a fixed menu of options to pick from. Hello, what is my bank balance? Done. Hello, can I move money from my savings to my current account? Done.
What level a Nigerian business needs depends on what work they do and how they do it. To be honest, most Nigerian businesses need simple AI tools or tools with options. Some need workflows.
A growing number of Nigerian businesses could benefit from agents, and that number is going to grow fast as more people see what’s possible.
What’s Next
This is an introduction to the world of AI agents and tools for the Nigerian business and the Nigerian developer. The goal is to understand the concepts so we know what we need when.
OpenAI, Anthropic, Google all have agent platforms ready to use. The challenge is they’re all AI agents built for Silicon Valley not for businesses in Lagos, Abuja, or Kano, nor for businesses across Africa. But we at Kade Labs can build exactly what you need, how you need it, and when. Because we would have done it for ourselves first.
At Kade Labs, we have built tools, the Job Scam Checker, the School Financial System, the WAEC JAMB Exam Success app, to name a few. Next, we are building agents, first for ourselves, then for you.
Kade Labs exists to create real value for Nigerian businesses, and to teach young Nigerians how to build that value themselves. Tool or agent, we build both, and we teach both.
If you run a Nigerian business and would like us to study your operations and build something specific for you, you can reach out to us. We want to spend some time watching how you actually run things. The first three people who reach out, we will work with.
If you want to learn to build these tools yourself, the Kade Labs Learning Path takes you from AI Explorer to AI Builder.
