Copilot — AI inside your Microsoft workday

For hundreds of millions of people, “the computer” means Windows, Outlook, Word, and Excel. Microsoft’s bet is the same one you saw with Gemini (E2·L4), aimed at the office instead of the search box: put the assistant inside the tools where the work already lives.

The fact sheet (community-verified)

What it’s typically good at

Copilot’s value is placement. Drafting a reply inside the inbox that has the thread; summarising the document that’s already open; turning a spreadsheet question into a formula without leaving the sheet; catching you up on a meeting inside the calendar that scheduled it. As a standalone chat it’s a capable general assistant; inside Microsoft 365 (on eligible plans), it becomes a colleague who has read the file.

What to keep in mind

Consumer and work Copilot are different animals. What it can access, what’s logged, and what your employer’s admins have enabled differ sharply between a personal account and a work one. At work, the right first question isn’t “what can Copilot do?” but “what has IT enabled, and what’s our usage policy?” (E8 builds this into a habit.)
In-document ≠ infallible. Having the file open reduces invention about the file — it doesn’t abolish E1·L7. Summaries of your documents still deserve the spot-check you practised with Claude (E2·L3).
Plan-dependence is the norm. Which apps get which features on which plan changes often; the card’s docs link outranks any month-old article.

If you use Microsoft tools: open a real document and ask Copilot (or the free chat at minimum) to “summarise this and list two questions a reviewer would ask.” Then answer honestly: did it read the document, or pattern-guess around it? If you don’t use Microsoft tools — skip guilt-free; L9’s tier logic covers what you need.

Check your understanding

1. At work, the most important Copilot question to settle first is: Which model version it runs What your organisation has enabled and what its usage policy allows Whether it beats other assistants at poetry

2. Copilot summarises the open document. The E1-consistent view is: Reading the file makes errors impossible Grounding in the file reduces invention; verification of specifics is still yours Summaries are only reliable in Word, not Excel

Recap

Placement is the product: real value inside the apps, with work-account governance as the first question and verification habits unchanged. Next: the assistants that live where you already scroll and chat.
