GILD verdict
Pick the assistant that matches your suite: Gemini for Google Workspace, Microsoft Copilot for Microsoft 365.
- The workflow
- Choosing a work assistant when the company standardizes on one productivity suite
- The decisive evidence
- DocumentedGemini comes inside Workspace plan prices, so 200 Business Standard seats cost US$2,800 a month with the suite, while Copilot Business adds US$4,200 on top of Microsoft 365, by GILD's calculation from published rates.110
- ReportedStanford keeps Gemini off inside Gmail and Docs over privacy and compliance while approving the Gemini app for high-risk data.15
- GILD analysisNo organization GILD found compared the two on the same work; the published accounts choose by suite and data class.
- The tradeoff
- Where you run both suites, decide by where the documents live. Either assistant answers from whatever a user can open, so both expose loose sharing, and running both means two sets of controls to keep in step.
- What would change the call
- If most documents sit in the other suite, or you need agents across many outside systems, compare Gemini Enterprise's connectors with Copilot's.
Pick by suite. Gemini carries no separate charge on a Workspace bill, while full Copilot adds US$21 or US$30 per user, by plan, on top of Microsoft 365. Google includes Gemini in Workspace Business and Enterprise plan prices. Microsoft includes Copilot Chat with eligible Microsoft 365 plans and sells full Microsoft Copilot, grounded in Microsoft Graph, separately. Each works best on the mail, files, and meetings people in its own suite can already open.
Choosing between Gemini and Microsoft Copilot
Choose Gemini if
- Your company runs on Google Workspace, where Business Standard at US$14 per user per month on an annual commitment already includes the Gemini app and Gemini in Gmail, Docs, Sheets, and Meet.
- You want one price per user that covers the suite and the assistant, with the AI Expanded Access add-on only for heavy users.
- You expect to need search and agents across non-Google apps, which Gemini Enterprise adds on a separate license.
Choose Microsoft Copilot if
- Your company runs on Microsoft 365, where Copilot works across Word, Excel, PowerPoint, Outlook, and Teams through Microsoft Graph.
- You want a baseline for everyone at no added cost (Copilot Chat) and paid licenses only for the people who need Copilot in the apps.
- Your compliance team already manages retention and labels in Microsoft Purview, which applies to Copilot interactions.

What practitioners report, side by side
Each product's figures come from its own practitioners, for the group you pick.
Overall signal
Leaders and teams rate Microsoft Copilot −3, 21 points above Gemini at −24. Most of the gap is in praise, with 12 of Microsoft Copilot's 40 sources positive against 10 of Gemini's 46. Microsoft Copilot has 13 negative and Gemini 20.
The score counts the authors from leaders and teams that take a side, one vote each with their latest view, and is how far positive votes lead negative ones, per 100 votes, so Gemini's −24 rests on votes split 9 positive, 16 mixed and 20 negative and Microsoft Copilot's −3 on 12, 13 and 13.
A lead of a fifth of the votes reads positive and a lead of half strong positive, with the same lines below zero. The dots show each source, positive, mixed, negative. Run a pilot on your team's recurring tasks to measure how often answers are used without rework.
