Our take
Choosing between Copilot and Gemini is less about comparing language model parameters and more about identifying your primary document repository. If your company revolves around Outlook calendars, Teams meetings, and nested Excel formulas, selecting Copilot is the logical path. The $18.00 per user a month add-on (paid yearly) integrates straight into your daily workflow, although the total lack of a free trial makes testing it with your team a paid experiment. If you try to force Gemini into a pure Microsoft environment, the experience breaks because of manual file transfers and poor document formatting. Conversely, if your workflows depend on Google Workspace, Gemini AI Pro at $19.99 a month is far more generous, providing 5 TB of cloud storage and advanced agentic capabilities. We often build custom AI chatbots for clients who realize these out-of-the-box assistants cannot access external CRM databases natively. If you operate a hybrid setup, Gemini offers the cheapest premium entry point with its $4.99 a month Plus tier.
