Microsoft 365 Copilot vs Gemini for Google Workspace

Microsoft 365 Copilot and Gemini for Google Workspace are the two productivity-suite AI assistants built directly into the apps your team already uses. The right choice is determined almost entirely by which productivity stack you run. Trying to bolt the wrong AI onto your stack creates governance gaps and inconsistent user experience.

Our Verdict

If your business runs Microsoft 365, Microsoft 365 Copilot is the only sensible choice — Gemini doesn't have visibility into your M365 data and can't reproduce the in-app workflows. If you run Google Workspace, Gemini is the better fit because it's deeply embedded in Gmail, Docs, Sheets, and Meet. The decision is a function of which productivity ecosystem your business committed to first.

Frequently Asked Questions

No. Microsoft 365 Copilot accesses only Microsoft 365 tenant data — it cannot read your Gmail, Google Docs, or Google Drive files. If you run Google Workspace, Gemini for Workspace is the AI assistant designed to integrate with your stack. Mixing the two creates governance gaps and a worse user experience.

Both are competitive on raw model capability. The meaningful difference is integration depth with your apps. Copilot is more deeply embedded in Excel for data work, while Gemini has stronger collaboration features in Docs. Once your team is committed to a productivity stack, the AI that integrates with that stack will deliver more value than the one that doesn't.

Almost never. The cost of migrating from Microsoft 365 to Google Workspace (or vice versa) far exceeds the difference in AI capability. Pick the AI that matches the suite you already run. If you're greenfield with no existing stack, choose the productivity suite first based on your team's preference, then add the corresponding AI later.
