Gemini vs Microsoft Copilot
The best AI sits inside the work.
Choose around the suite, files, permissions and habits your team already has—not whichever assistant won the latest demo.
For everyday SMB use (drafting emails, summarising docs, generating content, basic data analysis) Gemini is the better deal. It's cheaper (bundled), it's faster to release improvements, and the integration with Workspace apps is tighter because Google ships both. Copilot wins specifically in Excel-heavy work and in shops already deeply invested in M365.
Google Gemini (in Workspace)
Bundled with Workspace tiers, faster moving
Microsoft 365 Copilot
Add-on to M365, deepest in Excel/Word
Dimension by dimension.
| Dimension | Google Gemini (in Workspace) | Microsoft 365 Copilot | Winner |
|---|---|---|---|
| Pricing model | Included in Business Standard/Plus tiers | Add-on at ~£24/user/month on top of M365 | Google Gemini (in Workspace) |
| Model behind it | Gemini 2.x family (Google's latest) | GPT-4-class models via OpenAI partnership | Tie |
| Email drafting | Gmail (strong, fast | Outlook) strong, slightly heavier | Tie |
| Document drafting | Docs (clean, simple | Word) more controls, more friction | Google Gemini (in Workspace) |
| Spreadsheet analysis | Sheets (getting there | Excel) best by some distance | Microsoft 365 Copilot |
| Presentation generation | Slides (passable | PowerPoint) better designs out of the box | Microsoft 365 Copilot |
| Meeting summaries | Google Meet (built in, free with Workspace tiers | Teams) strong but requires Copilot licence | Google Gemini (in Workspace) |
| Asking questions across your files | Yes, across Drive | Yes, across SharePoint/OneDrive | Tie |
| Improvement velocity | Very fast, Gemini updates monthly | Steady but slower release cycle | Google Gemini (in Workspace) |
| Privacy/data handling | Workspace-tier protections | M365-tier protections (well-regarded) | Tie |
The real-world calls.
Existing Workspace customer
Choose: Google Gemini (in Workspace). Already included or cheap to add. No-brainer.
Existing M365 customer doing mostly Word + Outlook work
Choose: Microsoft 365 Copilot. Copilot is the path of least resistance. It works inside the apps you already use.
Existing M365 customer where staff barely use Word, mostly email + spreadsheets
Choose: It depends. If Excel work is the bulk of value, stick with Copilot. If it's mostly email, you're paying twice (once for M365, once for Copilot) when Workspace + Gemini would cover it for less.
Starting fresh or open to migration
Choose: Google Gemini (in Workspace). Workspace + Gemini at ~£13/user/month is significantly better value than M365 + Copilot at ~£36/user/month for similar real-world usefulness.
Excel power-user environment
Choose: Microsoft 365 Copilot. Copilot inside Excel is where it's most distinctive, natural-language formula creation, range analysis. Worth the premium if Excel work drives your business.
What we won't hide.
- Both products are improving constantly. Anything specific in this comparison may be out of date within months.
- Real productivity gain depends as much on team adoption as on the tool. We've seen Copilot rollouts underused and Gemini rollouts thrive, and vice versa.
- Neither tool replaces a bespoke AI build for your specific workflows. They handle horizontal tasks (email, docs); bespoke handles vertical tasks (your specific processes).
- Pricing changes regularly, verify current rates before committing.
