Gemini in Workspace rivals Copilot — and costs 33% less at entry level
Google Gemini is now integrated natively into Gmail, Docs, Sheets, Slides and Meet. At €20/user/month (Gemini Business) versus €30 for Microsoft Copilot, it offers a more accessible entry point for SMBs. Both ecosystems offer comparable features: email summarization, assisted writing, data analysis, presentation generation and meeting transcription. Based on our observations, companies on Google Workspace get a ROI comparable to those on Microsoft 365 — the difference comes down to the existing ecosystem and the quality of adoption, not the AI itself.
The problem
With the emergence of two major office AI ecosystems, IT decision-makers and SMB leaders face a strategic dilemma: which AI assistant to choose, and on what criteria? The tech press regularly compares the two solutions, but often from a technical angle that doesn't address companies' concerns.
The real stakes for an SMB or mid-market company:
- Ecosystem dependency: choosing Copilot or Gemini also means strengthening your commitment to Microsoft or Google. For companies already invested in one ecosystem, the choice is often obvious. For those in a mixed environment, the decision is more complex.
- Total cost of ownership: beyond the price of the AI license, you have to factor in the cost of the underlying Workspace or M365 licenses, training, any data migration and administration. The headline price gap (€20 vs €30) doesn't always reflect the real cost.
- Functional parity in motion: Microsoft and Google add features every month. A comparison that's 6 months old may be outdated. Companies need a stable decision framework that doesn't change with every product update.
- Adoption and company culture: the best tool is the one teams actually use. If your employees are familiar with the Google interface, forcing them toward Microsoft (or vice versa) to gain a marginal AI advantage is counterproductive.
This comparison aims to give you a pragmatic decision framework, based on business criteria rather than technical benchmarks disconnected from field reality. For an overview of augmented office productivity, see our pillar guide on augmented office productivity.
The AI solution
Here is a detailed comparison of Gemini's features in each Workspace application, with the strengths and weaknesses relative to Copilot in the equivalent Microsoft application.
Gmail + Gemini vs Outlook + Copilot
Gemini in Gmail excels at summarizing long discussion threads and contextual search ("find Martin's email about the Dupont contract from last month"). Assisted writing is fluid with good control of tone and length. Copilot in Outlook offers deeper integration with the calendar and contacts, and more contextual suggested replies thanks to the Microsoft Graph. Verdict: slight advantage to Gemini for search, to Copilot for organizational context.
Sheets + Gemini vs Excel + Copilot
It's on spreadsheets that the gap is the clearest. Copilot in Excel handles advanced formulas, pivot tables, VBA macros and anomaly detection. Gemini in Sheets generates basic formulas and charts but doesn't yet handle pivot tables or advanced statistical analyses. For SMBs with significant analytical needs, this is a decisive selection criterion. Verdict: clear advantage to Copilot in Excel. Details in our Excel augmented guide.
Meet + Gemini vs Teams + Copilot
Both platforms now offer real-time transcription, post-meeting summaries and follow-up action extraction. Transcription quality is comparable. Gemini in Meet adds real-time translation of subtitles in 18 languages. Copilot in Teams stands out for the ability to ask questions during the meeting ("what did Marie say about the schedule?") and for integration with Planner tasks. Verdict: near parity, with different advantages. See our guide to automating emails and meetings.
Implementation
Whether you choose Gemini or Copilot, the deployment methodology is similar. Here are the specifics to consider for Google Gemini in Workspace. For tailored support, discover our augmented office productivity offering.
Assess your company's Workspace maturity
Gemini works best if your data is already organized in Google Drive, if your teams actively use Gmail and Google Calendar, and if collaborative documents are in Docs/Sheets (not Office files uploaded into Drive). Audit your real usage: percentage of native Google documents vs imported Office files, use of Google Chat/Spaces, adoption of collaborative features. If more than 60% of your usage is native Google, Gemini will be fully effective.
Choose the right plan and deploy the pilot
Gemini Business (€20/month) is enough for 90% of SMBs: it covers Gmail, Docs, Sheets, Slides and Meet. Gemini Enterprise (€30/month) adds NotebookLM Plus, advanced search capabilities and enhanced security controls — reserved for regulated sectors or companies with high confidentiality needs. Deploy a 4-week pilot on 20 to 30 users, targeting Gmail (summarizing and writing) and Meet (transcription) as the first use cases.
Train, measure and expand
Organize a 2-hour hands-on workshop centered on your teams' real use cases. Show how to use Gemini to summarize an email thread, write a draft, analyze a Sheets file and take notes in a Meet meeting. Measure each week the number of Gemini interactions per user (available in the Google Admin console), the declared time saved and satisfaction. Expand in waves after validating the ROI.

Results
And what about Claude and ChatGPT?
Copilot and Gemini dominate integrated office work, but two other AI assistants deserve your attention for complementary uses:
| Tool | Vendor | Office strength | Limitation | Price |
|---|---|---|---|---|
| Claude Pro | Anthropic | Analysis of long documents (200k tokens), nuanced professional writing | No native Office/Gmail integration | €20/month |
| ChatGPT Plus | OpenAI | Advanced Data Analysis (built-in Python), versatility, custom GPTs | No native Office/Gmail integration | €20/month |
For most SMBs: choose Copilot or Gemini as your main tool depending on your suite, and subscribe to Claude or ChatGPT for the tasks where your main tool shows its limits — in-depth document analysis (contracts, long reports), creative brainstorming, or Python data analysis. The winning combination is often an integrated tool + a general-purpose assistant, for less than €50/user/month in total.
Frequently asked questions
Is Google Gemini as capable as Microsoft Copilot?
The two are comparable in terms of overall quality, with different strengths. Copilot excels in Excel (advanced formulas, pivot tables) and PowerPoint (generation of rich presentations). Gemini is stronger at searching for information in emails and Drive, and at generating long text in Docs. For meetings, the quality of summaries is equivalent between Teams and Meet. The choice depends more on your existing ecosystem than on the quality of the AI.
How much does Google Gemini cost for businesses?
Google offers two plans: Gemini Business at 20 euros per user per month (included in Google Workspace Business Standard and up), and Gemini Enterprise at 30 euros per user per month (advanced features, NotebookLM Plus notebooks, enhanced security). For an SMB of 30 users, the annual cost is 7,200 euros (Business) or 10,800 euros (Enterprise), to compare with Copilot's 10,800 euros.
Can you use Gemini and Copilot at the same time?
Technically yes, but it's not recommended for reasons of cost and complexity. If your company uses both ecosystems (Microsoft 365 and Google Workspace), it's more efficient to choose one main AI tool and pair it with specialized third-party tools (Otter.ai for meetings, Notion AI for documentation) rather than paying for two general-purpose AI assistants.
Does Gemini comply with GDPR for European companies?
Yes. Google Workspace with Gemini Enterprise offers data residency in Europe (EU regions), Workspace user data is not used to train the Gemini models, and Google is certified ISO 27001, SOC 2 and SOC 3. Google's DPA (Data Processing Agreement) explicitly covers AI processing. For regulated sectors, Gemini Enterprise adds advanced access controls and detailed audit logs.
