If your organisation runs on, or is moving to, Google Workspace, Gemini is the better choice. It is native in Gmail, Docs, Sheets, Slides and Meet, grounds its answers on your own Google data, offers a long context window and is priced competitively per seat, with full extensibility through Vertex AI for custom agents. Microsoft Copilot remains excellent for organisations committed to Microsoft 365 and Windows, its integration with the Office desktop apps and the Windows estate is unmatched, and a large M365 install base gets Copilot where their work already lives. The decision follows your productivity stack: Google estate to Gemini; Microsoft estate to Copilot.

Head to head
Office desktop integration. Copilot is wired natively into the Word, Excel, PowerPoint and Outlook desktop apps, if your teams live in the Office desktop suite, that depth is hard to match.
Windows and the M365 estate. Copilot reaches across Windows and the rest of Microsoft 365, so organisations already standardised on Microsoft get AI where their work already happens.
Install base. The sheer size of the M365 install base means Copilot meets most enterprises in tools they already own, no platform change required.
Native across Google Workspace. Gemini lives inside Gmail, Docs, Sheets, Slides and Meet, for Workspace organisations the AI is in every app they already use, with no add-on switching.
Grounded on your Google data. Gemini answers using your Drive, Gmail and Workspace content, and on Vertex AI it can ground on your wider enterprise data sources.
Long context. Gemini's long context window handles large documents and codebases in a single pass.
Competitive pricing. Gemini for Google Workspace is priced per seat as part of the Workspace stack.
Vertex / agent extensibility. The same Gemini models power Vertex AI, with an agent builder and the Google ADK for custom agents grounded on your data, the Copilot Studio equivalent, without leaving Google.
The decisive factor is your platform. If you are standardising on Google Workspace, paying separately for Microsoft Copilot means buying AI inside a suite you are leaving, double spend on overlapping capability. Gemini for Google Workspace is priced per seat within the Workspace stack, so AI sits with the productivity platform you already license, under one admin console and one set of governance policies. Beyond the in-app assistant, Vertex AI consumption is usage-based, so custom agents scale with what you actually run.
Moving from Copilot to Gemini is an enablement project, not a data migration, both assistants sit on top of your existing files, so there is no AI dataset to lift. The work is switching licensing, rebuilding prompts and custom agents against Gemini and Vertex AI, re-grounding on your Google data, and driving adoption.
