Microsoft Copilot is the AI layer woven into Windows 11, Edge, and the entire Microsoft 365 suite. It can summarize your emails, draft documents in Word, generate formulas in Excel, and build presentations in PowerPoint - without leaving the apps you already live in. At its core it runs on GPT-4o, with Bing's live web index giving it access to current information. The free version is available to anyone with a Microsoft account; Copilot Pro adds deeper integration with Office apps and faster response times for $20/mo. For enterprises already standardized on Microsoft's stack, this is often the path of least resistance to AI-assisted work. It doesn't do everything better than standalone tools, but it does it where you already are.
ChatGPT is OpenAI's flagship conversational AI, built on the GPT-4o and GPT-4 model family. It handles everything from drafting emails and summarizing documents to writing code and analyzing data. The free tier runs on GPT-4o mini, while Plus subscribers get access to GPT-4o, advanced reasoning with o1, image generation with DALL-E, and web browsing. The tool excels at multi-turn conversations where context matters - you can iterate on a piece of writing, debug code step-by-step, or explore a topic in depth across dozens of messages. Custom GPTs let users build specialized assistants for recurring workflows, and the platform integrates with plugins for tasks like booking travel or searching the web. ChatGPT has become the default general-purpose AI assistant for millions of users, from students writing essays to developers prototyping features. Its strength is breadth: it handles most tasks competently, even if specialized tools sometimes outperform it in narrow domains.
