Buy when Microsoft 365 is already the team hub and admin-controlled rollout matters. The economics rarely make sense for casual solo use. Needs manual review because Microsoft pricing pages can vary by region, promotion, and license bundle.
Security / privacy
Medium: Security review should focus on Microsoft 365 tenant permissions, Graph grounding, compliance controls, and oversharing risk from existing files.

Decision Criteria

Choose Microsoft 365 Copilot if

  • Outlook, Teams, Word, Excel, PowerPoint, SharePoint, and OneDrive are the team's daily workspace.
  • Your rollout depends on Microsoft tenant controls, identity, compliance, and existing procurement.
  • The biggest gains are meeting follow-up, email drafting, spreadsheet analysis, and Office document workflows.

Choose Gemini if

  • Gmail, Docs, Sheets, Slides, Drive, and Google Meet are the team's daily workspace.
  • Your buyers want Workspace-native AI without moving to Microsoft 365.
  • The first use cases are document drafting, Drive-based summaries, and Google Workspace collaboration.

Skip both if

  • Permissions are messy enough that AI could surface files people should not see.
  • Most users only need a lightweight assistant and not suite-connected context.
  • Security, legal, or IT has not approved account, file, email, and meeting data use.

Both are suite-sensitive buys. Compare total seat cost, required base licenses, admin controls, regional pricing, and whether casual users can stay on free or lower-cost assistants instead of receiving suite AI seats.

The privacy decision is mostly about tenant hygiene. Clean file, email, group, and meeting permissions before rollout, then validate retention, logging, admin settings, and compliance needs with current vendor documentation.
