Gemini and Microsoft Copilot are both ecosystem-embedded AI assistants, but they live in different worlds. Gemini integrates with Google Workspace — Docs, Sheets, Gmail, and Google Search. Copilot integrates with Microsoft 365 — Word, Excel, PowerPoint, Teams, and Outlook. The AI you choose should match the ecosystem you work in.
Beyond ecosystem integration, they have different standalone capabilities too. Gemini offers a 1M-token context window and native multimodal support. Copilot provides Microsoft Graph data grounding and enterprise security integration. Here's how to prompt each effectively.
