Pros
  • Has a free plan, so you can judge the writing quality before paying
  • Pro is $17/mo on annual billing ($20 monthly), and Claude Code comes included
  • Max tiers ($100 and $200/mo) include monthly API credits for building on the Claude Platform
  • Free Copilot chat on the web and in the app is genuinely usable
  • Microsoft 365 Premium bundles Office apps, storage and expanded Copilot
  • Works across Word, Excel and Outlook on paid plans
Catches
  • Usage limits are the #1 complaint. Users report weekly caps draining in days, especially with Claude Code
  • A temporary weekly-limit boost ended Sept 13, 2026, so limits feel tighter than they did this summer
  • Heavy users get pushed toward the $100–$200 Max plans fast
  • The free version lacks deep Office-app AI and agents
  • On Premium, AI benefits apply only to the subscription owner, not family members
  • For business, Microsoft 365 Copilot is an add-on: $18/user/mo yearly is a discounted price (regular $21), and it sits on top of a Microsoft 365 plan
