Microsoft 365 Copilot is powered by the “Copilot System”, a sophisticated processing and orchestration engine. It harnesses the power of three foundational technologies: The Microsoft 365 apps, that's Word, Excel, PowerPoint, Outlook, Teams, and more. The Microsoft Graph, that's all your content and context, your emails, files, meetings, chats, and calendar. And a Large Language Model, or LLM, a creative engine capable of parsing and producing human-readable text. All accessible through natural language.

You should also connect to the internet regularly to keep your version of Microsoft 365 up to date and to benefit from automatic upgrades. If you do not connect to the internet at least every 31 days, your apps will go into reduced functionality mode, which means that you can view or print your documents but cannot edit the documents or create new ones. To reactivate your apps, simply reconnect to the internet.

You do not need to be connected to the internet to use the Office apps, such as Word, Excel and PowerPoint, because the apps are fully installed on your computer.

Similarity checker is a feature within Microsoft Editor (available with M365) that checks a document for content that’s similar to text online and cites the original source.
