Chat & Assistants
Microsoft Copilot
AI built into Windows and Microsoft 365 — drafting in Word, formulas in Excel, meeting notes in Teams, all with your organisation's own data
Overview
What is Microsoft Copilot and what can it do?
Microsoft Copilot is an AI assistant embedded directly into the tools hundreds of millions of office workers already use daily: Word, Excel, PowerPoint, Outlook, Teams, and Windows itself. Rather than being a separate destination you have to visit, Copilot drafts documents inside Word, builds formulas and analyses data inside Excel, summarises unread email in Outlook, and produces meeting notes and action items automatically in Teams. For organisations, the Microsoft 365 Copilot tier connects the assistant to company data through Microsoft Graph — respecting existing access permissions — so answers and drafts can reference internal files, emails, and conversations rather than only general knowledge.

Our take on pricing
The free tier is a fine way to try Copilot but skips its best feature — in-app integration. Pro at $20/month is worth it the moment you rely on Word, Excel, or Outlook daily. Microsoft 365 Copilot at $30/user/month is a genuine organisational investment that only pays off with proper rollout and training, but the Graph-grounded answers are hard to replicate elsewhere.
Evaluation
Microsoft Copilot pros and cons
Pros
- Deeply embedded in the Office apps hundreds of millions of people already use daily
- Grounds answers in your organisation's own emails, files, and meetings via Graph
- Meeting summaries and action items in Teams save real, measurable time
- System-level presence in Windows extends assistance beyond any single app
- Copilot Studio allows building custom internal agents without writing code
Cons
- Most valuable features require a paid Microsoft 365 subscription on top of Copilot itself
- Little benefit outside the Microsoft ecosystem — Google Workspace users gain almost nothing
- M365 Copilot enterprise tier is expensive at scale across a large organisation
- No public developer API for building Copilot into third-party products

Verdict
Is Microsoft Copilot worth it in 2026?
Microsoft Copilot is not trying to be the most creative or the most technically impressive assistant — it is trying to be the most useful one inside the software you already spend your workday in, and largely succeeds at that goal. For individuals, the $20/month Pro plan pays for itself quickly if you regularly draft documents, build spreadsheets, or manage a busy inbox. For organisations, Microsoft 365 Copilot is a serious investment that requires real change management to pay off, but the Graph-grounded answers are a genuine differentiator no consumer-facing assistant can match. Outside the Microsoft ecosystem, there is little reason to choose Copilot over a general-purpose assistant.

Microsoft Copilot Review 2026: The Complete Guide to AI Inside Office
Microsoft Copilot takes a fundamentally different approach to the AI assistant market than ChatGPT or Gemini: rather than asking you to visit a new destination, it inserts itself into the software you are already using for work. This review examines what Copilot actually delivers across Word, Excel, Outlook, and Teams, and where the organisational Microsoft 365 tier earns its price.
How Copilot works across the Office suite
Copilot appears as a contextual panel or sidebar inside Word, Excel, PowerPoint, Outlook, and Teams, tailored to what each app actually does. In Word, it drafts and rewrites text based on a prompt or existing document content. In Excel, it can explain, build, and debug formulas, and generate charts and summaries from raw data. In Outlook, it summarises long email threads and drafts replies. In Teams, it automatically produces meeting notes, highlights action items, and can catch a user up on a meeting they missed entirely.
The system-level integration in Windows extends this further, allowing Copilot to take actions and answer questions about the operating system and installed applications rather than being confined to a browser tab.
Microsoft Graph: Copilot’s biggest differentiator
The single feature that separates Microsoft 365 Copilot from general-purpose assistants is Graph grounding. Rather than answering purely from general training data, Copilot can reference an organisation's actual emails, documents, spreadsheets, and Teams conversations — strictly within the requesting user's existing access permissions. Ask it to summarise "what happened on Project X this week" and it can pull from real emails and meeting transcripts rather than requiring you to paste that context in manually.
This is powerful, but it also means Copilot's value scales directly with how much of an organisation's work already lives inside Microsoft 365. Companies using a different core stack will find this advantage largely irrelevant.
Who should use Copilot?
Individual Office power users who spend significant time in Word, Excel, or Outlook see clear time savings from the Pro plan, particularly for repetitive drafting and data analysis tasks.
Organisations already standardised on Microsoft 365 get the most value from the enterprise tier, particularly teams that generate large volumes of email and meeting content that Copilot can summarise and act on.
Teams outside the Microsoft ecosystem will generally find less value here than in a general-purpose assistant, since Copilot's core advantages depend entirely on deep Office and Windows integration.
Copilot vs. ChatGPT and Gemini
ChatGPT and Gemini are built to be general-purpose assistants usable regardless of your software stack, with broader developer APIs and third-party integrations. Copilot deliberately trades that breadth for depth within a single ecosystem — if your organisation lives in Word, Excel, Outlook, and Teams, Copilot's Graph-grounded answers and in-app presence are difficult for a general assistant to replicate. Outside that ecosystem, the comparison tilts sharply back toward ChatGPT or Gemini.
Conclusion
Microsoft Copilot in 2026 is best understood not as a chatbot but as an operating layer across the software most office workers already use every day. For individuals embedded in the Office ecosystem, the Pro plan is an easy recommendation. For organisations, Microsoft 365 Copilot is a genuine investment that requires change management to realise its full value, but the Graph-grounded answers remain a capability no general-purpose competitor currently matches.
