Gemini for Google Workspace vs Microsoft 365 Copilot

Gemini for Google Workspace

The pricing page states that "your company data is not used to train models" for chats with Gemini, and the privacy notice covering Workspace adds a European Privacy Standards section and points to a Service Data Addendum. The captured pages give no retention periods for chats, files or agent transcripts, nothing on the model providers' own data terms, and we found no public information on where run logs live or on zero-retention options.

Microsoft 365 Copilot

Prompts, responses and Graph-accessed data are stated not to train the foundation models behind Copilot, a downloadable Data Protection Addendum covers business customers, users can delete their own Copilot history, abuse-monitoring human review is documented as opted out, and certifications include ISO 27001 and ISO 42001. The general privacy statement, though, says Microsoft "may use your data to develop and train our AI models" — enterprise agreements take precedence over it, but the captured pages give different statements on training, and I found no word on zero-data-retention terms with the named model providers or on admin-configurable retention of chat history.

Gemini for Google Workspace

Gemini is the named assistant across Gmail, Docs and Meet, and "Enterprise data regions" appears as an Enterprise-tier line item, but where inference runs and through which provider is not stated in the captured facts. We found no public information on pinning model processing to the EU, excluding model providers, or bringing our own model or key.

Microsoft 365 Copilot

OpenAI and Anthropic are named as the model subprocessors behind Copilot, and EU customers get the EU Data Boundary commitment with Copilot a covered workload since March 2024. Anthropic models are stated to be excluded from that boundary, worldwide traffic can be processed in the EU and other regions, and I found no documented way for an admin to pin every model to EU processing, exclude a provider, or bring their own key.

The tier comparison names serious governance — data loss prevention, context-aware access, Cloud Identity Premium, Vault and eDiscovery — with endpoint management stepped from Fundamental to Advanced to Enterprise. For what I need to run agents safely, we found no public information on SSO or SCIM provisioning, group-level permissions for models, agents or connectors, audit log export, or usage reporting and its scope.

Microsoft 365 Copilot

Retrieval inherits source-system permissions twice over — Copilot surfaces only data the user has at least view rights to and the Semantic Index honours the identity boundary — and admins can select which agents are allowed at all, with Purview and Content Search to manage stored interactions and Entra plus role-based access control for tenant isolation. What holds it back: the captured pages do not document SCIM provisioning, exportable audit logs, or group-level permissions per model and connector, and the scope of usage reporting is not spelled out.

Gemini for Google Workspace

The assistant sits natively in Gmail, Meet, Chat, Drive and Docs, with Office file interoperability, a Workspace Migrate tool, and AppSheet sold as a no-code platform with "advanced integrations". As my bridge into ERP, CRM and ticketing that leaves me stranded: we found no public information on a documented API, MCP or webhooks, on connector sync behaviour, or on source citations for grounded answers.

Microsoft 365 Copilot

There is a real connector pipeline — bring external data into Microsoft Graph, register schemas with semantic labels, manage access to external items — plus a documented connectors API, Graph REST APIs with SDKs, change notifications and Teams bots, and grounded answers store citations to what they used. I found no public information on MCP support or incremental sync behaviour on the captured pages, which is what an automation shop would probe next.

Gemini for Google Workspace

Workspace Studio is described as letting you "automate your workday with intelligent AI agents", an add-on grants "more Workspace Studio automations", and daily caps on Audio Overviews show usage metering. The captured pages stop there: we found no public information on actions with scoped permissions, human approval before an agent sends anything, run logs, or testing and evaluation before a company-wide rollout.

Microsoft 365 Copilot

Copilot Studio builds agents on a visual canvas with pre-built tools, the Agents Toolkit deploys across Copilot, Teams, web and third-party messaging channels, and agents can be created, tested and deployed from Visual Studio Code — so there is a test-before-release story, plus jailbreak and cross-prompt-injection classifiers and admin gating of which agents may run. What I could not find on the captured pages: per-action human approval, run logs, triggers and schedules, or scoped per-agent permissions — and for agents that file tickets and chase approvals, those guardrails have to be in writing.

Gemini for Google Workspace

A privacy notice covering Workspace exists with a dedicated European Privacy Standards and GDPR section, but hosting location is unconfirmed on the captured pages, and the generative-AI privacy hub names Google as the processor of customer data without stating a headquarters or any EU contracting entity. With Google LLC of Mountain View as the vendor and US Cloud Act exposure flagged, the captured facts show neither EU hosting nor a named model-provider subprocessor.

Microsoft 365 Copilot

The EU Data Boundary is a contractual commitment in the Product Terms with Copilot a covered workload, a Data Protection Addendum is offered, and the model providers — OpenAI and Anthropic — are named as subprocessors. The boundary is not total, though: Anthropic models are excluded from it, some customer and professional-services data continues outside in limited circumstances, the privacy statement says personal data may be stored in the United States and other jurisdictions, and the vendor here is Microsoft Corporation, Redmond, USA — so what is proven is EU hosting and named subprocessors, not a European chain end to end.

Starter, Standard and Plus are priced publicly in euros per user per month — €6.80, €13.60 and €21.10 at regular rates, billed monthly with a 16% annual-commitment saving — plus an introductory offer for new customers limited to the first 20 users for 12 months, a 300-user cap on self-serve tiers and daily caps on Audio Overviews. But add-ons are listed as "sold separately" without prices, and we found no public information on Enterprise tier pricing, overage rates for automations, or the cost of AI Expanded Access — so a real annual cost for an agent-heavy deployment stays out of reach.

Microsoft 365 Copilot

The licensing pages document real structure — eligible Office 365 plans, an annual-commitment Business add-on capped at 300 users per tenant, education and government channels — but I found no public price figure on the captured pages: no per-seat amount, no usage limits, no overage rates. A buyer cannot compute an annual cost from these pages alone.
