Cons

Frequently Asked Questions

5 questions

  1. Yes. Microsoft Copilot is free in Windows 11/12 and Bing with unlimited daily usage. However, document integration (OneDrive, SharePoint) requires Microsoft 365. Copilot Pro ($20/month) adds GPT-4 access but still needs 365 for full document features.
