Consumers like the free web version for quick research and writing, and power users feel Copilot Pro is fairly priced compared with competing AI subscriptions.

Final verdict
The best AI assistant for Microsoft 365 users, but less ideal outside that world.
Copilot at copilot.microsoft.com is a strong choice if you live in the Microsoft ecosystem, offering tight integration with Microsoft 365 apps and work data alongside a capable free tier. The $20 Copilot Pro plan gives power users faster responses and desktop app integration at a competitive price point, while the $30 business add-on targets organizations that need compliance and admin controls. Its biggest strengths are security, permission-aware document access, and seamless presence across Windows, Edge, and Office. However, non-Microsoft users and those wanting open APIs or fine-grained model control may find specialized AI platforms more flexible.
