Microsoft Copilot Alternatives

ChatGPT is OpenAI's conversational AI assistant and the closest all-round alternative to Microsoft Copilot. It handles writing, coding, research and data analysis in one place, and you can refine every result in a natural back-and-forth conversation. Unlike Copilot, it works as a standalone assistant that is not tied to Windows or Microsoft 365, so you can use it in any browser or app. A free plan is available, with premium plans for heavier use and extra features.

Best for: everyday writing, coding help, brainstorming and general-purpose AI assistance.
