Copilot vs ChatGPT: Complete Comparison 2026
Microsoft Copilot vs OpenAI's ChatGPT — an ironic rivalry since Copilot is powered by OpenAI's own GPT models. This comparison covers Microsoft 365 integration, pricing, features, coding, and real-world performance to help you choose the right AI assistant.
⚡ Quick Answer
Copilot is better for Microsoft 365 power users who want AI directly in Word, Excel, PowerPoint, and Outlook. ChatGPT is better for creative work, coding, custom GPTs, plugins, and general-purpose AI use.
