explanation for non-techies**

Imagine you have a personal assistant who helps you with your daily tasks. This assistant remembers your preferences, like how you like your coffee or what time you prefer to have meetings. Over time, the assistant gets better at anticipating your needs because they remember your past interactions and choices. This is similar to what Microsoft Copilot is doing with its new updates.

Microsoft Copilot, part of Microsoft 365, is like a digital assistant that uses your chat history to give you more relevant and personalized responses. Think of it as having a conversation with someone who knows your background and can provide answers that fit your specific context. This means that when you ask Copilot a question or request help, it can tailor its responses based on what it has learned from your previous interactions.

To make this process more transparent and manageable, Microsoft has updated the settings so you can easily see what Copilot remembers about you. You can also adjust your personalization preferences, much like how you might tell your assistant to stop reminding you about a certain task or to start prioritizing a new one.

This enhancement is available across various platforms, including Android, iOS, Mac, and the web, making it accessible whether you're at your desk or on the go. Just as you would trust a well-informed assistant to help streamline your workday, Microsoft Copilot aims to do the same by using your chat history to provide smarter, more contextual assistance.
