Quick Verdict
Microsoft Copilot is excellent in Teams, solid in Word and Outlook, underwhelming in Excel, and inconsistent in PowerPoint. Teams meeting summarisation — real-time transcription, action item extraction, and queryable meeting history — is genuinely the best implementation of AI in any productivity suite. Word drafting and Outlook email management work well enough to save meaningful time for heavy users. Excel AI remains unreliable for anything beyond basic formula generation. PowerPoint creates functional but visually uninspired slides.
Worth £30/user/month? For organisations with 50+ people who live in Microsoft Teams and use Word and Outlook daily, yes — the meeting AI alone justifies a significant portion of the cost. For smaller teams, lighter M365 users, or anyone whose primary AI needs are writing quality and analytical depth, a £20/month standalone assistant (Claude Pro or ChatGPT Plus) delivers better output at lower cost. The details matter — read on for the full breakdown.
The Copilot Landscape
“Copilot” is Microsoft’s brand name for at least five different AI products that share a name but deliver very different experiences. Understanding which is which matters — because “I tried Copilot and it wasn’t great” might mean you tried the wrong one.
Microsoft 365 Copilot is the premium add-on ($30/user/month on top of M365 E3/E5) that embeds AI inside Word, Excel, PowerPoint, Outlook, and Teams. This is what most enterprise buyers evaluate and what this review primarily covers.
Copilot Chat is the free conversational assistant available to M365 business users. It answers questions using web data but doesn’t access your organisation’s emails, files, or meeting history. Starting April 15, 2026, Microsoft is removing Copilot Chat from Word, Excel, PowerPoint, and OneNote for users without a paid Copilot licence — a significant change that restricts free AI access in Office apps.
Copilot in Windows is built into Windows 11, offering system-level AI assistance (settings management, file search, general Q&A). Useful but limited — more of a convenience feature than a productivity tool.
Copilot in Edge/Bing provides AI-powered search and web page summarisation in Microsoft’s browser. Genuinely useful for research and web browsing, available free to all Edge users.
GitHub Copilot is the developer-focused code completion tool — a separate product with separate pricing ($10–39/month). It’s unrelated to M365 Copilot beyond the name. For a full review, see our Best AI Coding Assistants comparison.
What’s Actually Working
Three Copilot features reliably deliver value in daily use — and they’re all about reducing the time you spend on routine information processing rather than creative generation.
Teams meeting summarisation is genuinely excellent. This is Copilot’s standout feature and the one most consistently praised by enterprise users. Copilot transcribes meetings in real time, generates structured summaries with key decisions and action items, identifies who committed to what, and lets you query the meeting afterwards (“What did we agree on the timeline?” or “What concerns did Sarah raise about the budget?”). For professionals who attend 5+ meetings per day, this alone can save 30–60 minutes of daily note-taking and follow-up. The January 2026 update added meeting scheduling from Copilot Chat — finding available times, booking rooms, drafting agendas — which further reduces calendar management overhead.
Word drafting has improved significantly. The new Agent mode (rolling out through March 2026) helps refine documents through multi-step iteration rather than one-shot generation. Instead of producing a single draft and leaving you to edit, Copilot now asks clarifying questions (audience, tone, level of detail), generates a structured first draft, and then responds to conversational refinement — “make the executive summary more concise” or “add a risk section after the financial projections.” The output quality for internal documents — reports, memos, proposals, meeting agendas — has reached a level where the drafts require 15–20 minutes of editing rather than an hour of writing from scratch.
Outlook email management works. Copilot summarises long email threads accurately, drafts replies that match your communication style, prioritises your inbox by sender importance and content urgency, and handles the “schedule a meeting with everyone on this thread” request that previously took 10 minutes of calendar checking. The recent expansion to include your entire inbox and calendar context makes Copilot in Outlook meaningfully more contextual than the earlier version that only worked with the current email.
Across all apps, the organisational grounding is the unique advantage. Because Copilot connects to Microsoft Graph — your emails, files on SharePoint and OneDrive, Teams conversations, and calendar — it understands your organisational context in a way that ChatGPT and Claude fundamentally cannot. “Summarise what our team discussed about the product launch this week” pulls from Teams chats, meeting transcripts, emails, and shared documents automatically. No standalone AI assistant can replicate this without you manually providing every piece of context.
What’s Still Overhyped
Four areas where Copilot’s daily reality doesn’t match Microsoft’s marketing.
Excel AI is inconsistent and untrustworthy. This is Copilot’s weakest application and the one where the gap between demo and reality is widest. Copilot generates formulas from natural language prompts — “calculate the year-over-year growth rate for each product” — and it works for straightforward requests. But complex multi-sheet logic, conditional calculations, and data transformation tasks produce unreliable results that require manual verification. Users consistently report needing to double-check Excel Copilot’s output more than in any other app. For data analysis where accuracy matters, Claude Pro’s file upload and analysis (or ChatGPT’s code interpreter) produces more thorough and reliable analytical output. Excel Copilot is adequate for formula suggestions; it’s not a data analyst replacement.
PowerPoint creates functional but uninspired presentations. Copilot generates slides from prompts or existing documents with correct content structure and clean layout. But the designs look like competent corporate templates — they lack the visual sophistication of dedicated AI presentation tools like Gamma or Beautiful.ai. For internal presentations and routine updates, the output is acceptable. For client-facing decks, investor pitches, or any context where visual impression matters, you’ll spend significant time refining the design — or use a dedicated presentation tool for the 20% of decks that need to look impressive.
Output quality feels generic for creative tasks. Copilot excels at information processing — summarising, organising, extracting, and reformatting existing information. It’s weaker at generating genuinely original content. Marketing copy, creative writing, thought leadership, and strategic analysis produced by Copilot tend to sound corporate and template-driven compared to output from Claude or ChatGPT. The organisational context that makes Copilot strong for information retrieval doesn’t help when the task requires original thinking rather than synthesis.
The “Copilot everywhere” promise is fragmented. Despite the unified branding, each Copilot instance (M365, Windows, Edge, GitHub) works differently, has different capabilities, and doesn’t share context between them. A conversation in Copilot Chat doesn’t inform what Copilot does in Word. A GitHub Copilot code suggestion has no connection to your M365 Copilot experience. The “one AI that works across everything” marketing message doesn’t match the reality of several distinct products that happen to share a name.
Is Copilot for M365 Worth £30/User/Month?
The ROI calculation depends entirely on how much your team uses Teams meetings and how deeply embedded you are in the Microsoft ecosystem.
When it’s worth it: organisations where professionals attend 4+ Teams meetings per day (meeting summarisation alone saves 30+ minutes daily — worth far more than £1/day), teams that do most of their document work in Word and Outlook (the drafting and email management features provide consistent time savings), and enterprises where organisational grounding — Copilot understanding your company’s files, emails, and conversations — creates genuine value that standalone assistants can’t replicate.
When it’s not worth it: teams where meetings primarily happen on Zoom or Google Meet (Copilot’s meeting features only work in Teams), small teams of fewer than 20 where the £30/user/month premium adds up faster than the time savings justify, organisations where the primary AI need is writing quality or analytical depth (Claude Pro at £20/month produces better output for these tasks), and teams that use M365 lightly — if your workflow centres on Slack, Notion, and Google Docs with occasional Word use, Copilot’s value proposition collapses.
The cost reality: for a 50-person company, Copilot costs £18,000/year on top of existing M365 licensing. Microsoft reports that only about 3% of M365 commercial users pay for Copilot (15 million out of 450 million). A Recon Analytics survey found that when workers have access to ChatGPT, Claude, Gemini, and Copilot, only 8% choose Copilot as their primary tool. These adoption numbers suggest the market hasn’t yet validated Copilot’s premium pricing for most use cases.
Copilot vs Alternatives
Copilot vs ChatGPT Plus ($20/month) for the same business tasks: ChatGPT produces higher-quality writing, more versatile output (images, voice, plugins), and more creative content. Copilot wins on organisational context (it knows your company’s data) and native Office integration (no copy-paste between apps). For a hybrid approach, many professionals use Copilot for in-app convenience and meeting AI, then switch to ChatGPT for quality-sensitive work.
Copilot vs Claude Pro ($20/month) for document analysis: Claude produces more thorough, better-reasoned analysis with superior writing quality. Upload a 50-page report to Claude and ask for an executive summary — the output is consistently stronger than Copilot’s equivalent in Word. Copilot’s advantage is that it can pull from your SharePoint and OneDrive files without manual upload, and the output appears natively in Word. Claude’s advantage is that the analysis is deeper and the writing is better.
The optimal combination: Copilot for Teams meetings and in-app Office convenience + Claude Pro or ChatGPT Plus for quality-sensitive writing, analysis, and creative tasks. This costs £50/user/month total but covers every AI need at the appropriate quality level. For most professionals, this hybrid outperforms either tool alone.
Frequently Asked Questions
Is Copilot for M365 included in my subscription?
Not automatically. The free Copilot Chat is currently included with qualifying M365 business subscriptions, but starting April 15, 2026, Microsoft is restricting Copilot Chat access in Word, Excel, PowerPoint, and OneNote for users without a paid licence. Full Microsoft 365 Copilot requires an additional licence: $30/user/month for organisations with 300+ users, or $21/user/month for businesses with 300 or fewer users. This is on top of your existing Microsoft 365 subscription. Personal and Family plan users get limited AI credits rather than the full enterprise Copilot experience.
Can I try Copilot before paying?
For enterprise: Microsoft offers pilot programmes, typically 30–90 days with a limited number of seats, before requiring a full contract. Contact your Microsoft account representative to arrange a trial. For individual evaluation: Copilot Chat (the free, web-grounded version) is available now to all M365 business users, though with reduced functionality after April 2026. This lets you experience Copilot’s interface and basic capabilities, but doesn’t demonstrate the full organisational grounding and in-app features that the paid version provides.
Is Copilot getting better over time?
Yes — measurably so. The January 2026 Agent mode update for Word, Excel, and PowerPoint improved the editing experience significantly, moving from one-shot generation to iterative refinement. Outlook’s expanded context window now includes your full inbox and calendar. Teams meeting features continue to add capabilities (meeting scheduling, cross-meeting search). The trajectory is clearly positive. However, the pace of improvement varies by app — Teams and Word are improving rapidly, while Excel’s AI capabilities remain the weakest link. Microsoft’s investment in Copilot is massive and sustained, so continued improvement is expected. The question for buyers is whether the current state justifies the current price, or whether waiting 6–12 months for further maturation would be more prudent.
