Microsoft 365 Copilot
by Microsoft
AI assistant inside Outlook, Teams and the Microsoft 365 apps
Reviewed by the the30top research team · Last reviewed 2026-10-27
Overview
Copilot works inside the Microsoft 365 apps to summarise emails, draft documents, automate tasks and analyse data, with pre-built and custom agents. Microsoft states data protection stays within Microsoft 365 boundaries and lists GDPR among its compliance standards. It is strongest for teams already on Microsoft 365, requires a qualifying licence, and acts as a general work assistant rather than a dedicated executive-assistant product.
Our verdict
The obvious default for Microsoft shops that want email, meeting and document help in one place. Confirm the current add-on price with Microsoft before budgeting.
Best for
Organisations already on Microsoft 365 that want AI inside the tools executives use every day.
Avoid if
You run on Google Workspace or want a standalone assistant without Microsoft licensing.
