What it actually is
Copilot is Microsoft’s assistant, and it exists in several forms at once: a web chatbot, a sidebar in Edge and Windows, and a deeply integrated layer inside Word, Excel, Outlook and Teams. That sprawl is confusing, but it reflects the strategy — Microsoft is not trying to win the chatbot comparison, it is trying to make AI unavoidable inside software you already pay for.
What it’s genuinely good at
- Working inside documents. “Turn this into a two-page summary” in Word, or “explain what this formula does” in Excel, is genuinely useful because it already has the file open.
- Email and meetings. Summarising a long thread in Outlook, or pulling action items out of a Teams call, removes real drudgery.
- Enterprise compliance. For organisations, the data-handling and compliance story is stronger and easier to get past a security review than most alternatives.
- No adoption problem. It is already installed. Whatever its merits, nobody has to decide to start using it.
Where it falls short
As a chatbot it is mid-pack. For open-ended questions, drafting or analysis, ChatGPT and Claude are both noticeably better.
The pricing is genuinely confusing. Free Copilot, Copilot Pro, and Microsoft 365 Copilot are different products at different prices with overlapping names. Work out which one you are actually buying before you pay.
It is pushed aggressively. Prompts appear across Windows and Office whether you want them or not, which some users find actively irritating.
Value depends entirely on your ecosystem. If you do not use Office heavily, most of what makes Copilot distinctive is irrelevant to you.
Who should use it
People and organisations already committed to Microsoft 365, particularly those who spend their day in Word, Excel and Outlook. Also the pragmatic choice for businesses where compliance and admin control matter as much as capability.
Choose something else if: you want the best raw model quality (Claude or ChatGPT), you live in Google Workspace (Gemini), or you mainly need a chatbot rather than an Office assistant.
Pricing
A free tier exists with limited access. Copilot Pro, around $20 a month for individuals, adds priority model access and some Office integration. Microsoft 365 Copilot is a separate per-user business add-on costing considerably more, and is the version with full document integration — check which tier provides the features you actually want, because the naming does not make this obvious.
Alternatives worth considering
- ChatGPT — the better general assistant, with a far wider ecosystem.
- Google Gemini — the equivalent choice if your files live in Google rather than Microsoft.
- Claude — the strongest option for writing and careful analysis, if you do not need Office integration.
Our verdict: a mediocre chatbot and a genuinely useful Office assistant. Whether it is worth your money depends almost entirely on one question — how much of your working day happens inside Microsoft apps. If the answer is “most of it”, the integration is worth paying for; if not, use a better chatbot for free.
Frequently asked questions
Is Copilot free?
Partly. There is a free tier with limits. Copilot Pro adds priority access for individuals, and Microsoft 365 Copilot is a separate, more expensive business add-on.
What is the difference between Copilot Pro and Microsoft 365 Copilot?
Pro is an individual subscription mainly for the chatbot and some app features. Microsoft 365 Copilot is a per-user business add-on that works inside your own documents and mail — a substantially different product.
Copilot or ChatGPT?
Copilot if the work happens in Word, Excel or Outlook. ChatGPT for breadth, better general answers, and a much larger ecosystem.
Is my company data safe with Copilot?
For business tenants, data handling and compliance commitments are comparatively strong, which is why many organisations standardise on it. Confirm the specific terms for your licence rather than assuming.
