Microsoft 365 Copilot

The AI assistant already inside the apps you use every day.

What it is

A model, plus your own work data

A language model that writes and summarises, connected to your emails, chats, files and meetings through the Microsoft Graph. It only uses what you already have permission to see.

What you do with it

Three verbs

DraftMake something new — a doc, an email, a deck.

SummariseShorten a thread, a meeting, a long file.

AskQuestion content you already have.

Pick the verb, then open the app where the content lives.

Where it shows up

Match the task to the app

Word — draft, summarise, ask about a document
Outlook — summarise a thread, draft a reply, coaching tips
Teams — catch up on a meeting or chat you missed
Excel — formula and chart suggestions, data insights

Get a useful answer

Four parts of a good prompt

Goal — what you want produced
Context — why, or who it's for
Source — what Copilot should use
Expectations — length, format, tone

Then read it back. The four parts get a strong draft; your judgement makes it right.

Remember

Draft. Summarise. Ask.

A model plus your data. A clear prompt. A quick check before you use it.
