Ask ten people what Microsoft Copilot is, and you will get ten answers, because Microsoft attached the name to at least five different products. The free chatbot, the version inside your Office apps, the work version that reads company data, the agent builder, and a separate coding tool from GitHub all carry it. They cost different amounts and do different things. This review covers the assistant at copilot.microsoft.com and the Microsoft 365 versions built on it. Judged on capability alone, it is good rather than remarkable. Judged on where it sits, inside the apps most offices already run, it is hard to ignore.
What Is Microsoft Copilot?
Copilot is Microsoft’s AI assistant, and the name now covers a whole product family rather than one tool. It began as Bing Chat in 2023, was renamed, and then spread across almost everything Microsoft sells.
Three versions matter to most readers. The free consumer chat at copilot.microsoft.com works with a Microsoft account and answers questions using web data. Consumer Microsoft 365 subscriptions add Copilot inside the desktop Word, Excel, PowerPoint, and Outlook apps. Microsoft 365 Copilot is the work licence, and it is the only version that reads your organisation’s email, files, chats, and meetings through Microsoft Graph.
That last distinction is the whole product. Everything else Copilot does, a free chatbot can also do. Reading your actual inbox is what you are paying for.
One clarification, since search results mix them constantly: GitHub Copilot is a separate coding tool with separate pricing, and AWS Copilot belongs to Amazon. Neither is covered here.
| Best for | Main use | Pricing model | Platforms | Key limitation |
|---|---|---|---|---|
| Microsoft 365 organisations and subscribers | Drafting, email triage, meeting notes, data work | Freemium, paid plans from $9.99 per month (checked 8 Aug 2026) | Web, Windows, macOS, iOS, Android, Edge, Microsoft 365 apps | Business tiers require a separate paid Microsoft 365 licence |
How Does Microsoft Copilot Work?
In the free chat, you type a question and get an answer with web citations. Nothing needs setting up beyond signing in.
Inside the Office apps, Copilot appears as a side panel. In Word it drafts and rewrites. In Excel it explains formulas and builds analysis. In PowerPoint it turns a document into slides. In Outlook it summarises long threads and drafts replies.
The work version adds a retrieval step. Before answering, it searches your permitted organisational content, then writes a reply grounded in what it found. Microsoft calls this layer Work IQ. Because it respects existing permissions, Copilot should only surface files you could already open. That also means messy permissions become visible fast, which catches some companies out during rollout.
Above that sit prebuilt agents such as Researcher and Analyst, and Copilot Studio for building your own. Agent usage is metered in Copilot Credits rather than covered by the seat licence.
Key Features
- Work data grounding. Answers built from your own emails, documents, meetings, and chats, within existing permissions.
- Copilot in Office apps. Drafting in Word, analysis in Excel, slide generation in PowerPoint, thread summaries in Outlook.
- Meeting recap in Teams. Summaries, action items, and answers about what was said in a call you missed.
- Copilot Vision. Visual assistance that answers questions about what is on your screen or camera.
- Prebuilt agents. Researcher produces cited reports and Analyst handles data work, both on licensed plans.
- Copilot Studio. Build custom agents for your organisation, billed through Copilot Credits.
- Image generation. Included on the free tier with limits, with higher allowances on paid consumer plans.
Performance And Experience
Chat responses arrive fast. Anything that scans your mailbox or document library is slower, since retrieval happens before generation.
Quality is uneven by app rather than by model. Outlook summaries and Teams recaps are consistently the strongest work, because summarising is what the retrieval step does best. Word drafting is competent but generic. Excel is the weakest, and complex requests often need reworking. Users regularly report that Copilot cannot find a file they know exists, which usually traces back to indexing or permissions rather than the AI.
The interface is familiar, since it lives in apps people already use. The confusion is upstream. Plan names changed twice in a year, the standalone Copilot Pro subscription was retired, and features vary by licence, so many users cannot tell which capabilities they should have.
One buried limitation deserves attention. On Microsoft 365 Family and Premium, the AI features belong to the subscription owner only. Five other household members get the Office apps but not Copilot.
Pricing And The Real Cost
| Plan | Monthly | Yearly | What it adds |
|---|---|---|---|
| Copilot (free) | $0 | $0 | Web chat, limited image generation, Copilot Vision. No access to your files. |
| Microsoft 365 Personal | $9.99 | $99.99 | Copilot inside desktop Office apps, 1 TB storage, one person. |
| Microsoft 365 Family | $12.99 | $129.99 | Up to six people and 6 TB, but AI features stay with the owner alone. |
| Microsoft 365 Premium | $19.99 | $199.99 | Highest usage limits, AI agents for research and analysis, priority model access. |
For organisations, the picture is different. Microsoft 365 Copilot is roughly $30 per user per month on an annual commitment, with a lower Business tier for companies under 300 users. Both are add-ons. You need a qualifying Microsoft 365 plan underneath, so a realistic all-in figure lands closer to $60 or more per user. Copilot Chat, the web-grounded version, comes free with eligible business plans but cannot see internal data. Business pricing has moved several times in 2026, so confirm current rates before budgeting.
Our Microsoft Copilot Verdict: Is It Worth Using?
Copilot is best understood as a distribution win rather than a technology win. Microsoft did not build the strongest assistant, but it put a capable one inside the apps hundreds of millions of people open every morning, and connected it to their real work. For summarising a forty-message email thread or catching up on a missed meeting, nothing else is close.
The frustrations are equally clear and largely self-inflicted. The naming is a mess, and the widespread public complaints about Copilot often turn out to be people using a different product than they think. Pricing is opaque because business seats sit on top of licences you must already hold. Quality varies sharply between apps, with Excel well behind Outlook. And the family sharing restriction is buried in footnotes where buyers will not see it. Worth it if your work already lives in Microsoft 365. Hard to justify otherwise.
Suggestions For Improvement
- Rename the product family so free chat, app Copilot, and work Copilot are clearly distinguishable.
- Show users in-product which version they have and what data it can currently reach.
- State the AI sharing restriction on family plans at the point of purchase, not in a footnote.
- Publish a single all-in price example showing base licence plus Copilot together.
- Improve Copilot in Excel, which lags the other Office apps by a visible margin.
- Give clearer errors when a file cannot be found, separating permission issues from indexing delays.
