If you’ve decided AI might be worth a try but you’re staring at a wall of names — Claude, ChatGPT, Gemini, Copilot — and wondering which AI you should use for your business, you’re asking exactly the right question. The tools all look similar from the outside, the marketing all sounds the same, and it’s genuinely hard to tell what suits a small West Coast business from what suits a Silicon Valley tech firm. This guide breaks down the main options in plain English, so you can make a sensible choice based on what you actually do each day rather than the hype. (If you’re still weighing up whether to bother with AI at all, our guide on how to start using AI in your business is the better place to begin — this one is about picking a tool once you’ve decided to.)
The main AI assistants, in plain English
Most of the “AI” people talk about for everyday business use comes down to a handful of chat assistants. You type a question or request, and they write back — a bit like messaging a very fast, very well-read colleague. Here are the four you’ll hear about most.
- ChatGPT (OpenAI). The one that started the fuss and the name most people recognise. It’s a strong all-rounder for writing, brainstorming, summarising and answering questions.
- Claude (Anthropic). Excellent at writing that sounds natural, working through longer documents, and giving careful, well-reasoned answers. Many people find its tone the most human of the bunch. It’s the assistant I use most day to day.
- Gemini (Google). Google’s assistant, which ties in neatly with Gmail, Google Docs and the rest of Google Workspace if that’s where your business already lives.
- Copilot (Microsoft). Microsoft’s assistant, built into Windows and the Microsoft 365 apps — Word, Outlook, Excel and Teams. If your office runs on Microsoft, this one meets you where you already work.
Here’s the reassuring part: for most small-business tasks, all four are very capable. You are not going to ruin anything by picking the “wrong” one. The differences matter more as you lean on them harder.
Which AI should I use for my business? Match the tool to the job
The honest answer to “which AI should I use for my business” is: start with what fits how you already work, then judge it on results. A few practical steering points:
- If your business runs on Microsoft 365, try Copilot first. Having AI built straight into Outlook and Word, on files you already have, saves a lot of copying and pasting.
- If you live in Gmail and Google Docs, Gemini will feel the most at home for the same reason.
- If your main job is writing — emails, quotes, website copy, social posts, newsletters — Claude and ChatGPT are both superb, and it’s worth spending an afternoon with each to see whose tone you prefer.
- If you just want to try AI with no commitment, the free version of ChatGPT or Claude is the easiest front door. Open it in your browser and start asking.
You don’t need to overthink this. Pick the one closest to where you already spend your day, give it a fortnight of real tasks, and you’ll quickly get a feel for whether it earns its place.
Free versus paid — what you actually get
Every one of these tools has a free tier, and for many owners the free version is genuinely enough to start with. You can draft emails, tidy up writing, summarise a long document and answer everyday questions without paying a cent.
The paid plans (usually around NZ$30–$40 a month per person) generally give you three things: access to the smarter, more capable version of the assistant, higher usage limits so it doesn’t cut you off mid-task, and extra features like handling images, files and spreadsheets. Microsoft and Google also sell their AI as an add-on to your existing 365 or Workspace subscription.
There’s one difference that matters more than the features, though: what happens to what you type. On the free versions, the information you enter can be used to help train the AI — so anything sensitive could, in theory, end up shaping future models. You can usually switch this off in the settings (look for “Data Controls” or similar), but it’s often switched on by default and easy to miss. Paid business accounts usually have this switched off by default, which is one of the main reasons to upgrade once you’re using AI for real work.
My advice is the same as always: start free, get comfortable, and only upgrade once you can clearly see the tool saving you time or money. There’s no prize for paying early, and no shame in staying on the free tier if it does the job.
Keeping your business data safe
This is the part worth slowing down for. As a rule of thumb, treat anything you type into a free, public AI tool as though it could be stored and looked at. That means no customer details, no financial records, no passwords, and nothing private or commercially sensitive.
The good news is that the paid business versions — particularly Microsoft Copilot and the business plans from OpenAI and Anthropic — come with much stronger privacy commitments, including promises not to train their models on your data. If you’re going to use AI on anything involving customer or business information, that’s the sort of setup you want, configured properly — we cover this in depth in is my information safe when using AI?. It’s also where a little local guidance pays off, so you’re confident your obligations under the Privacy Act are covered. If you’d like a hand weighing up the options, that’s exactly what our AI consulting is for.
How to choose without overthinking it
If you take one thing from this article, let it be that choosing an AI tool is not a permanent, high-stakes decision. It’s more like choosing which supplier to trial. Here’s the simple path:
- Pick the one closest to your existing tools — Microsoft, Google, or a standalone like Claude or ChatGPT.
- Use the free version on real tasks for a fortnight — the boring, repetitive jobs, not clever party tricks.
- Judge it on time saved, not on how impressive it feels.
- Only pay when the value is obvious, and switch tools freely if another suits you better.
None of this needs a big budget or a technical background. And just as a tidy, well-managed website makes everything else online run more smoothly, the right AI tool — chosen for good reasons and set up safely — quietly gives you time back each week. If your foundations need attention too, our website management service keeps that side ticking over from $49 a month.
A local hand to help you choose
There’s no single “best” AI, only the one that fits your business, your budget and the way you like to work. If the choice still feels murky, you don’t have to sort it out alone. As a local business myself, I’m happy to give you an honest, plain-English steer — including telling you if a tool isn’t worth it for you yet.
