How many products does Microsoft have named ‘Copilot’? I mapped every one

Update (9 Apr 2026): Another one. A helpful person sent in Microsoft 365 Copilot for US Government. That's 81. Chart updated.

It reminds me of around 2002 when Microsoft named everything ".net".
Yep, I remember downloading a beta version of what would be eventually released as Windows Server 2003. The beta version was called Windows .Net Server 2003.
I had some books that referred to it as .NET Server printed before the name change. In the long history of terrible Microsoft names, this was a rare case where they were able to right the ship.
And “one” like most Fortune 500 companies.
one.copilot.net
Soon: Copilot .NET .
Azure PowerCopilot Live .NET
Or when IBM renamed everything Websphere.
Then they did the same thing to a lesser degree with "360", including the Xbox.
