"Microsoft Copilot Review 2026: The M365 Assistant"
Microsoft Copilot is the AI assistant embedded across Microsoft 365 — Word, Excel, PowerPoint, Outlook, and Teams. Its value is not raw model quality but context: it reads your documents, inbox, and calendar to do work where your data already lives. The free tier is a basic GPT-4 chat; the paid tiers unlock app integration.
