Glossary AI technique
Microsoft Copilot
What is Microsoft Copilot?
Microsoft Copilot is the AI assistant Microsoft has built into Word, Excel, Outlook, Teams and other 365 apps, for writing, summarising and searching.
Copilot makes individual employees faster in the tools they already use: drafting an email, summarising a meeting, finding a document. It works with what you have in Microsoft 365.
What Copilot does not do by itself is take over processes or connect data from systems outside Microsoft, such as your accounting or industry software. That takes integrations and often an AI agent.
When Copilot is enough and when your own layer pays off is covered in Copilot or an AIOS layer.
