Claude, Copilot or ChatGPT?

The question I get asked more than any other right now. Three serious AI tools, three different strengths, and a straight answer about which one your team should actually be using, and why it might be more than one.

Almost every week, a business owner asks me some version of the same question: "We want to get serious about AI, should we be on Copilot, ChatGPT, or this Claude thing everyone keeps mentioning?" It's a fair question, and the honest answer is more interesting than the one most people expect. These aren't three versions of the same product fighting over the same job. They're three good tools that are genuinely best at different things, and the businesses getting real value have usually worked out which is which.

So here's how I actually think about them, in plain English, without the vendor noise.

Microsoft Copilot: the one that lives where your work already is

Copilot's superpower has nothing to do with being the cleverest model in the room. Its superpower is location. It sits inside Microsoft 365, inside Word, Excel, Outlook, Teams and your actual company data, and that proximity is worth more than a few IQ points on a benchmark. It can summarise the meeting you just sat in, draft the reply grounded in the thread it can already see, and pull from your real documents without you copying anything anywhere.

That also makes it the safest starting point for most organisations, because the data never leaves the Microsoft tenancy you've already secured and paid for. If your team lives in Office every day, and most do, Copilot is the AI that meets them where they are. The trade-off is that it's most powerful inside that Microsoft world and less of a free-roaming generalist. For day-to-day business productivity, that's usually a feature, not a limitation.

ChatGPT: the generalist that set the pace

ChatGPT is the one that put this whole category on the map, and it's still a brilliant generalist. It's the tool I'd point someone to for the widest range of everyday tasks: brainstorming, explaining, drafting, turning a rough idea into something structured. The ecosystem around it is deep and moves fast: custom GPTs you can shape for a specific job, a huge community, voice and image features.

Where you have to be deliberate with ChatGPT is governance. Used through a personal account, your team's prompts and pasted content are sitting outside your business's control, and that's exactly the kind of quiet data-leak that turns into a compliance problem later. The answer isn't to ban it (that never works), it's to put it on the right business footing with the right settings, so people get the capability without the exposure.

Claude: the one we reach for when the thinking is hard

Claude, from Anthropic, is the one I reach for when the work is genuinely demanding: long, dense documents that need to be held in one piece, careful reasoning, serious writing, and code. It's very good at staying coherent across a large amount of material without losing the thread, and it has a measured, considered tone that suits high-stakes writing where you don't want a confident-sounding mistake.

For knowledge-heavy work, like picking apart a long contract, reasoning through a messy problem or drafting something that actually has to be right, it's often the strongest of the three. It's less about living inside your email and more about being the sharpest thinking partner when the question is hard. That's why it's earned a permanent place in how our own team works.

The honest answer: most teams end up using more than one

Here's the part the vendors won't tell you, because each of them wants to be your single answer: the businesses getting the most out of AI rarely pick just one. They use Copilot inside Microsoft 365 for the daily flow of email, documents and meetings; they reach for ChatGPT or Claude when they need a heavyweight generalist or a serious thinking partner for a specific task. The tools aren't really competitors in your business; they're a small toolkit, and the skill is knowing which one to pick up.

That's also the bit that doesn't come in the box. Handing your team three logins doesn't make them productive any more than handing someone a full toolbox makes them a builder. The value is in the judgement: what to use when, how to brief it well, what to keep out of it, and where the guardrails go.

So how do you actually choose?

Start with where your team already works. If that's Microsoft 365, and for most businesses it is, get Copilot working properly first, because it's the lowest-friction win and the safest with your data. Layer a business-grade ChatGPT or Claude on top for the heavier, more open-ended work, with the governance set up so it's an asset and not a leak. Then spend the real effort not on the licences but on the habits, because that's where the gap between a clever toy and a genuine advantage actually lives.

The businesses pulling ahead with AI didn't pick the right tool. They learned which tool to pick up, and when. And that's a skill, not a subscription.

If you want a shortcut, that's exactly what our AI training and workshops are for. We'll show your team all three in the context of your actual work, sort out the governance so nothing leaks, and leave them knowing which tool to reach for and how to get the most from it. No hype, just the practical judgement that turns AI from a novelty into something that quietly compounds.
