Copilot or ChatGPT: which one for a small office?
Short answer: use the one that lives where your work already lives. Here’s how to tell which that is, and a fair way to test them before you pay.
This question comes up in almost every office I visit, usually because someone’s nephew swears by one and the IT person swears by the other. The honest answer is less exciting than either of them: they’re all good now, and the best one for you mostly depends on software you already use.
These products change quickly, including names, features and prices. The general picture below holds, but check the current details before you buy.
The short answer
- If your office runs on Microsoft 365 (Outlook, Word, Excel, Teams), start with Copilot.
- If your office runs on Google Workspace (Gmail, Google Docs, Google Drive), start with Gemini, which is built into Workspace.
- If you use a mix, or mostly use other software, start with ChatGPT, which works well on its own and doesn’t care what else you use.
That’s the right starting point for most small offices. The rest of this page is for when it isn’t obvious.
What actually differs
| Copilot | ChatGPT | Gemini | |
|---|---|---|---|
| Best fit | Microsoft 365 offices | Mixed setups, or standalone use | Google Workspace offices |
| Where you use it | Inside Outlook, Word, Excel and Teams, or in its own chat window | In its own app or website | Inside Gmail, Docs and Drive, or its own app |
| What it can see | With the paid version, your email, files and meetings, if you allow it | What you paste or upload, plus files you connect | With Workspace, your email and Drive files, if you allow it |
| Business privacy | Work accounts come with business data protections | Business plans don’t train on your data by default | Workspace plans don’t train on your data by default |
Where you use it matters more than which is “smartest”
The biggest difference isn’t how clever the answers are. It’s how many steps it takes to use. If drafting an email reply means copying it out of Outlook, pasting it into a chat window, and copying the draft back, you’ll use it less than if a button inside Outlook does it for you. Tools that live where you already work get used. Tools that need a separate window get forgotten.
What it can see changes what it can do
A chat tool that only knows what you paste in is a very good writer. A tool that can see your email and files, with permission, can answer questions like “what did we quote the Hendersons last spring?” That’s powerful, and it’s also why the setup and permissions deserve a careful afternoon.

Cost
All three have free versions that are fine for learning. For business use, plan on roughly $30 to $45 CAD per person per month for any of them, often less if it’s bundled into a plan you already pay for. Check what’s already included in your current Microsoft or Google subscription before you buy anything. You may already have more than you think.
When the short answer is wrong
- You’re on Microsoft 365, but your team already loves ChatGPT. Habit beats features. A tool people already use well is worth more than a better one they won’t open.
- You mostly need writing help, not searching your files. Any of the three will do; pick the one that feels easiest.
- You work alone. Take the one with the free or cheapest plan that matches your email, and don’t overthink it.
- You handle sensitive information (health, legal, financial). Choose based on privacy terms and settings first, features second, and get it set up properly before real client information goes in.
A fair two-week test
If you can’t decide, test them on your real work instead of reading more comparisons.
- Pick three real jobs you do every week. For example: replying to a common customer question, summarizing a long email thread, and drafting a quote or proposal.
- Do each job in both tools for a week, with customer names removed.
- Keep a simple tally: which draft needed less fixing, and which one was quicker to get to.
- Ask whoever does the admin. Their vote counts double. They’re the one using it every day.
At the end of two weeks, the answer is usually obvious, and it’s based on your work, not someone’s review.
The mistake to avoid
The most common mistake isn’t picking the wrong tool. It’s buying seats for everyone, giving no guidance, and waiting for magic. Three months later, two people use it and everyone else has forgotten the login.
Whichever you pick, give everyone the same starting point: the three jobs it’s for, a few instructions that work, and what never goes in. That’s the difference between a tool you pay for and a tool you use.
If ChatGPT wins, ChatGPT for small business: which plan, and what it costs in CAD shows which plan to buy. A good first job to test both on is a quote, and How to write quotes faster with AI walks through it.
