Companies that run Microsoft 365 and Google Workspace are choosing which half of their work gets an assistant. Copilot is wired into Microsoft 365 and Gemini into Google Workspace. This comparison shows what each reaches, then names the third lane: Kortix, the open-source system you can point at both.
Microsoft Copilot is Microsoft's assistant inside Word, Excel, PowerPoint, Outlook and Teams, across desktop, mobile and web, grounded in an organization's own content through Microsoft Graph and Work IQ. It is closed and runs as a Microsoft 365 service. (Microsoft Copilot)
Google Gemini for Workspace is Google's AI woven into Gmail, Docs, Sheets, Meet, Chat and Vids, with an agentic layer in Gemini Enterprise. It is closed and runs on Google's cloud. (Gemini for Google Workspace)
The two answer different halves of a company. Copilot reaches the Microsoft 365 side and Gemini reaches the Google Workspace side, and a question about the other side is where each one stops.
A company that runs Microsoft 365 and Google Workspace is choosing which half of its work gets an assistant. Copilot reads Microsoft 365 content that a person has permission to see, through Microsoft Graph; Gemini retrieves the Google Workspace content a person has access to. Work that crosses the two suites falls to whichever assistant is open, and the answer comes back partial.
Google documents one way across the gap: Gemini Enterprise connects agents to business apps "like Microsoft 365, Salesforce, SAP, Jira, and more". Microsoft's Copilot stays inside the Microsoft 365 experience. Neither reaches the other vendor's suite as its own ground. That mismatch is why teams shortlist Microsoft 365 Copilot alternatives, and why Copilot for Teams alone rarely settles the decision.
Both are bought per seat on top of a suite. Microsoft 365 Copilot is an add-on that requires a qualifying Microsoft 365 plan, sold for up to 300 people on an annual commitment (checked October 2026). (Copilot pricing) Gemini in Workspace apps is limited on Business Starter and included on Business Standard and higher tiers (checked October 2026). (Workspace pricing)
Kortix comes first because it is the only column you can host and point at both suites.
# kortix.yamltriggers: - slug: daily-digest type: cron cron: '0 0 9 * * 1-5'From the Kortix README: a trigger in kortix.yaml that runs an agent on a cron schedule.
The open-source AI Operating System is Kortix: it holds your agents, their skills, your company memory, and every connector in one git repo you own. Connectors: 3,000+ apps in a click, plus MCP, OpenAPI, Postman, GraphQL and raw HTTP, so one system can reach both the Microsoft 365 tools and the Google Workspace ones. One isolated sandbox per session. Each session has its own isolated machine and branch.
Session work reaches main through a change request. Merge is default-deny for agents, so a person reviews what lands. Run it on Kortix Cloud, in your VPC, or on your own on-prem network. Self-host is free. (Kortix docs)
The answers to common questions cover the rest of the switch, and the guide to open-source Copilot alternatives lists the field.
Neither Copilot nor Gemini covers both by default. Each is wired into its own suite, and reaching across is partial. An open-source system you host connects to both, so the assistant layer stops tracking the suite.
No. Both are closed services that run on the vendor's cloud, and neither ships a self-host path. Kortix runs on Kortix Cloud, in your VPC, or on your own on-prem network.
Your Microsoft 365 and Google Workspace plans, the apps people open, and the files inside them. You replace where the agents and memory live while keeping the suites you already pay for.
