For most businesses, start with one general assistant and learn it well. ChatGPT is the safe all-rounder, Claude is the best writer and the strongest on long documents, Copilot makes sense if you live in Microsoft 365, Gemini if you are a Google Workspace shop, and Perplexity is for research with sources.
The worst move is spreading thinly across five tools. Pick one, get genuinely good, then add a second only when you hit its limits.
The single most common question I get is some version of "there are a hundred of these things, which one do I actually use?" It is a fair question, and the marketing does not help. Every tool claims to be the best at everything, which is a bit like every pub claiming to do the best Sunday roast in the county. Someone is fibbing.
So here is the plain version, based on using these tools every day rather than reading their press releases.
The five that matter
| Tool | Best at | Start here if... | Rough price |
|---|---|---|---|
| ChatGPT | General all-rounder, images, voice, huge feature set | You want the safe, popular default that does a bit of everything | ~£17/mo |
| Claude | Writing, long documents, careful reasoning, coding | Quality of writing and handling big files matters most to you | ~£14/mo |
| Microsoft Copilot | Working inside Word, Excel, Outlook and Teams | Your business runs on Microsoft 365 already | ~£19/mo add-on |
| Google Gemini | Working inside Gmail, Docs and Sheets | You are a Google Workspace business | ~£17/mo add-on |
| Perplexity | Research with live sources and citations | You need answers you can check and reference | ~£16/mo |
Prices move around and there are free tiers for all of them, so treat those figures as a guide rather than gospel. The differences that actually matter are about fit, not a couple of quid a month.
Do not start with five. Start with one.
The instinct, once you realise these tools are useful, is to sign up for everything and end up with five half-used subscriptions and a vague sense of guilt. Resist it. Every tool has its own quirks, its own way of being briefed, its own personality. You get far more from being genuinely fluent in one than from being a tourist in all of them.
Think of it like learning to drive. You do not learn in five different cars at once. You learn in one, get confident, and then any car feels familiar. AI tools are the same. The core skill, briefing them clearly and checking their work, carries across all of them.
How to actually pick
Forget the feature lists. Answer two questions. First, where does your work already live? If your team is in Outlook and Excel all day, Copilot sitting inside those apps removes friction you did not know you had. If you are a Google shop, Gemini does the same job. Second, what is the job you most want help with? If it is writing that reads like a human wrote it, Claude is hard to beat. If it is research you can trust and cite, Perplexity earns its place.
A sensible first-tool decision, in order
- Microsoft 365 business? Try Copilot first - it is already where you work
- Google Workspace business? Try Gemini for the same reason
- Neither, or you want the best standalone? ChatGPT for range, Claude for writing
- Research-heavy role? Add Perplexity as your second tool
- Still unsure? Start with the free tier of ChatGPT or Claude and upgrade what you actually use
Not sure which stack fits your business?
We help teams choose the right one or two tools and get properly good at them, rather than collecting subscriptions.
The mistake that costs the most
It is not picking the "wrong" tool. Honestly, any of the big five will serve most businesses well, and switching later is easy because the skill transfers. The expensive mistake is buying a tool, handing out logins, and assuming people will figure it out. They will not. They will use it like a slightly better Google, get underwhelmed, and drift back to the old way of doing things.
A short piece of proper training turns a tool your team ignores into one they cannot work without. That is the difference between a subscription you quietly cancel and one that pays for itself many times over. If you want a hand choosing and then actually embedding it, that is exactly what our programmes are for.
Pick one. Learn it well. Add the next when you hit a wall. That is the whole strategy.
Frequently asked questions
What is the best AI tool for a small business?
There is no single winner, but ChatGPT is the safest all-round starting point and Claude is the best if writing quality matters most. If you already use Microsoft 365 or Google Workspace, Copilot or Gemini remove friction by working inside the apps you use.
Is it better to use one AI tool or several?
Start with one and get fluent. The core skill of briefing and checking transfers across tools, so mastering one beats dabbling in five. Add a second only when you hit a clear limit, such as needing research with citations.
Should I use the free or paid version to start?
The free tiers are good enough to test whether a tool fits. Once one tool becomes part of someone's daily work, the paid version usually pays for itself within a week through saved time and better output.
Is ChatGPT or Copilot better for business?
Copilot wins if your business lives in Microsoft 365, because it works inside Word, Excel and Outlook. ChatGPT is the stronger standalone tool with more features. We compare them fully in ChatGPT vs Copilot for business.
How long does it take to get good at an AI tool?
Most people reach a genuinely useful working level within a few weeks of regular use, and a single focused training session gets them there far faster than trial and error.
