Before you start

  • A computer, a tablet or a phone with a recent internet browser
  • An internet connection
  • Be at least 13 years old according to Microsoft, older in some countries: check the age requirement for your country on the official page
  • Optional: a Microsoft account, an Apple ID or a Google account

Copilot is Microsoft’s artificial intelligence assistant. You can use it directly in your browser, without downloading any software. This tutorial shows you how to open it safely.

Check the address before you click

Be careful with fake sites. Microsoft says the official addresses are copilot.cloud.microsoft and copilot.com. The address copilot.microsoft.com redirects to copilot.com.

To be sure, go through Microsoft’s official page. Open it, then use the “Open Copilot” button.

A page that asks for your password without using these addresses is not trustworthy. Close it.

Open Copilot in your browser

Type the official address in your browser’s address bar, or click the “Open Copilot” button on Microsoft’s page. The Copilot home page appears.

You can type your question in the input box, just like in a messaging app.

Choose whether to sign in

To chat, the copilot.com page may ask you to sign in. You can do this with a Microsoft account, an Apple ID or a Google account.

According to a Microsoft help page, signing in is not required. However, it gives you access to your conversation history, image creation and longer conversations. Check the options shown on the screen.

Understand the differences between versions

Copilot in the browser (or in the app) is free. Microsoft says it is available at no cost.

The Copilot built into Word or Excel is a separate offer. It is reserved for Microsoft 365 subscribers or holders of business licenses. For prices and plans, check Microsoft’s official website.

If someone talks to you about “Copilot in Word”, this does not mean you have free access to it.

Keep your bearings after an update

Microsoft says an updated version of the Copilot app has been available since August 18, 2026. The interface may therefore differ from what this tutorial describes. The main steps stay the same: official address, optional sign-in, input box for writing.

And now?

Try these two simple requests to get familiar with the tool:

  • “Explain what artificial intelligence is, in plain words.”
  • “Help me write a short message to thank a friend for their help.”
