In short: The choice between Microsoft Copilot and Google Gemini is, in most cases, decided by which productivity suite your business already uses. If your team runs on Microsoft 365, Copilot is the natural AI layer. It works inside the apps your people already use and connects to your organisational data. If your business uses Google Workspace, Gemini is already included in your subscription and embedded across Gmail, Docs, Meet and Sheets. Running both platforms puts you in genuinely contested territory, and that is where the comparison below becomes useful.
ⓘ Note on Gemini’s business availability: Google restructured its AI pricing in early 2025. Gemini is now bundled into all paid Google Workspace Business and Enterprise plans at no additional cost. There is no longer a separate Gemini add-on for these tiers. An optional AI Expanded Access add-on (approximately £13 per user per month) unlocks higher usage limits and advanced features including Workspace Studio automations and greater image and video generation capacity.

Understanding each tool
Microsoft 365 Copilot
Copilot is Microsoft’s AI assistant embedded across the Microsoft 365 suite. It works inside Word, Excel, Outlook, Teams and PowerPoint, helping users draft, summarise, analyse and automate without leaving the application they are working in. Its key advantage is access to your organisational data via the Microsoft Graph. It can summarise email threads, generate meeting notes from Teams calls, surface relevant documents and draft responses with full context of your business. For businesses already invested in the Microsoft stack, including Dynamics 365, Business Central and the Power Platform, Copilot offers the most joined-up path to AI across your entire technology estate.
- Summarise Teams meetings and generate action items automatically
- Draft Outlook emails with context from prior correspondence
- Analyse Excel data and generate charts from natural language prompts
- Native AI integration across Dynamics 365 and Business Central
- Mature process automation through Power Automate and Copilot Studio
Google Gemini (in Workspace)
Gemini is Google’s AI assistant embedded across Google Workspace. For businesses that use Gmail, Google Docs, Sheets, Slides and Meet as their primary tools, Gemini is already present and active on Business Standard and above plans, included in the subscription cost with no additional add-on required. It offers writing assistance in Docs and Gmail, data analysis in Sheets, note-taking in Meet and, on higher tiers, image and video generation. Google’s Workspace Studio, introduced in 2026, enables no-code AI agent creation for teams that want to automate workflows within the Google ecosystem.
- AI writing and drafting across Gmail, Docs and Slides
- Automated meeting summaries and action items in Google Meet
- Natural language data analysis and formula generation in Sheets
- Included in all paid Workspace Business and Enterprise plans
- Workspace Studio for no-code automation and agent creation
Practical use cases: which tool for which task?
Copilot reads the full thread and drafts with Microsoft Graph context. Gemini does the same in Gmail.
Copilot, native to Microsoft Teams. Gemini provides the same functionality in Google Meet.
Gemini. Image generation is built into Workspace on higher tiers. Standard M365 Copilot plans do not include native image generation.
Copilot in Excel or Gemini in Sheets, depending on which platform your team uses.
Gemini. Included in Google Workspace Business Standard from approximately £11.80 per user per month with no AI add-on required.

Frequently Asked Questions — Microsoft Copilot vs Google Gemini
Common questions from UK businesses comparing Microsoft Copilot and Google Gemini, answered by Advantage, Microsoft Solutions Partner and Microsoft Copilot deployment specialist.
Is Microsoft Copilot better than Google Gemini for business?
The honest answer is that the comparison depends almost entirely on which productivity suite your business uses. For Microsoft 365 users, Copilot is the stronger AI layer. It connects to your Microsoft Graph data, works inside the apps your team already uses and integrates with Dynamics 365 and the Power Platform. For Google Workspace users, Gemini is already embedded in your subscription and has comparable functionality within the Google ecosystem.
Where the comparison becomes relevant is for businesses evaluating a platform switch, or those running both platforms at the same time. In that scenario, the cost structure favours Google. Gemini is included in Workspace plans whereas full Copilot carries an additional per-user cost. Advantage helps Microsoft-first UK businesses get the most from their existing Microsoft investment, including Copilot deployment and readiness.
Does Google Gemini work with Microsoft 365?
No. Gemini is designed to work within the Google Workspace ecosystem. It does not connect to your Microsoft 365 emails, Teams meetings, SharePoint documents or Outlook calendar. If your business uses Microsoft 365 as its primary productivity suite, Gemini will not provide the in-the-flow AI experience that Copilot delivers within those applications.
There is a standalone Gemini app available separately that provides general AI assistance without Workspace integration, but it operates like any other standalone AI tool. It can only work with information you manually provide, not your organisational data.
Is Gemini cheaper than Copilot for business?
For businesses already on Google Workspace Business Standard (from approximately £11.80 per user per month on annual billing direct from Google), Gemini AI is included at no additional charge. This makes it considerably cheaper than adding the full Microsoft 365 Copilot add-on on top of an existing M365 subscription, where Copilot carries an additional per-user cost.
This comparison only holds if your business is already using, or is willing to move to, Google Workspace. Switching productivity suites carries its own cost, including migration, retraining and workflow disruption, that typically exceeds any per-seat AI saving for established Microsoft-first businesses. Advantage can help you model the total cost of your Microsoft stack, including Copilot, against any proposed alternative.
What is Google Workspace Studio and how does it compare to Copilot Studio?
Google Workspace Studio, introduced in 2026, allows users to create AI agents and automate workflows within Google Workspace without writing code. It is Google’s response to Microsoft’s Copilot Studio and Power Automate, enabling non-technical users to build automations that connect Google apps and trigger AI actions.
Microsoft’s Power Automate and Copilot Studio are more mature platforms with a larger library of connectors, more sophisticated workflow logic and deeper integration with enterprise systems including Dynamics 365 and Business Central. For businesses with complex process automation requirements, the Microsoft Power Platform remains the stronger choice. Workspace Studio is a meaningful development for Google-first organisations wanting to automate within the Google ecosystem without technical resource.
