FAQ
Is Microsoft Copilot the same as ChatGPT?
No. Microsoft Copilot is Microsoft's own assistant integrated into Microsoft 365 products; ChatGPT is OpenAI's standalone conversational assistant. Both use large language models, but they serve different ecosystems and workflows.
Can ChatGPT replace Microsoft Copilot for office work?
For most standalone drafting tasks it can, but it won't have the deep Microsoft 365 integration — such as reading your inbox or summarizing a Teams meeting — that Copilot provides natively.
