Microsoft Copilot Pro
$20 per mo (plus M365 for app features)
Claude Pro
$20 per mo (less billed annually)
Microsoft Copilot Pro embeds AI inside Word, Excel, Outlook, and PowerPoint, ideal if you live in Microsoft 365. Claude Pro is a standalone assistant prized for writing, analysis, and long documents. Both cost $20. Copilot wins inside Office; Claude wins on standalone output quality.
Pick Microsoft Copilot Pro if you live in Word, Excel, Outlook, and PowerPoint and want AI directly inside those apps.
Pick Claude Pro if you want the best standalone assistant for writing, analysis, and long documents.
Microsoft Copilot Pro and Claude Pro both cost $20 a month, but they are used very differently. Copilot Pro puts AI directly inside Microsoft 365: it drafts in Word, builds formulas in Excel, summarizes Outlook, and creates PowerPoint slides, where you already work. Claude Pro is a standalone assistant, accessed through its own app and site, celebrated for the quality of its writing, its handling of long documents, and a careful, steerable style.
The catch with Copilot Pro is that its in-app features assume you also have a Microsoft 365 subscription. Claude is self-contained. So the choice hinges on whether you want AI inside Office (Copilot) or the best standalone writing-and-analysis assistant (Claude).

Things neither product's marketing page leads with.
Copilot Pro's best value is inside Microsoft 365, so you really need an Office subscription for it to shine.
Claude is more capable for standalone writing and analysis, but it does not live inside your Office documents.
Both cost $20, so the decision is about where you work and what you need, not price.
