Claude vs Microsoft Copilot — Structured Comparison Data
Machine-readable comparison dataset for Claude vs Microsoft Copilot. Contains 221 attribute comparisons, 5 FAQ pairs.
Claude vs Microsoft Copilot — Attribute Category Vocabulary
Taxonomy of attribute categories used to classify comparison data for Claude vs Microsoft Copilot.
Which AI is better for analyzing long documents or codebases?
Claude is significantly better for long-form analysis. Its 200,000 token context window lets you paste entire books, research papers, or large codebases in a single message without losing context. Microsoft Copilot's 32,000 token limit (6.25x smaller) requires you to break large documents into chunks, losing continuity and requiring multiple prompts.
Can I use Copilot in Microsoft Word and Excel?
Yes—Microsoft Copilot is natively integrated into Microsoft 365 applications. In Excel, it can suggest formulas and analyze data; in Word, it drafts and edits content; in Outlook, it composes emails; in Teams, it summarizes meetings. Claude requires third-party plugins or the web interface and lacks these native integrations.
Claude scores 94/100 on the HumanEval benchmark vs. Copilot's 81/100, making Claude 13 points higher for code generation quality. Claude is also better for understanding complex legacy code due to its larger context window. However, Copilot's integration into Visual Studio and GitHub Copilot provides better workflow integration for developers already in Microsoft's ecosystem.
Only Microsoft Copilot has real-time web search via Bing integration, letting it retrieve current news, weather, stock prices, and live data. Claude cannot search the web independently, making it less suitable for tasks requiring real-time information. Claude compensates with lower hallucination rates on factual tasks due to its training data cutoff.
Both offer free tiers. Claude.ai is free with usage limits (~100K tokens/month). Microsoft Copilot is free with a Microsoft 365 subscription (which ~400 million people already have) or integrated into Bing. For standalone use, Claude Pro ($20/month) offers unlimited access; Copilot Pro costs $20/month separately. Total cost depends on your existing software stack.
