Copilot Got a New Name. Your Invoice Got a New Shape.

Three Names, One Feature, Four Months

Microsoft announced a persistent, always-on AI agent called Scout at its Build developer conference in June 2026, describing it as a colleague that keeps working after a person logs off. On September 25 the same agent reappeared under a third name, Autopilot, inside a redesigned Copilot app that also folds in chat, document editing and a new app-building tool called Code.

Chief executive Satya Nadella framed the release as a new operating system for work, according to GeekWire's report on the launch. The rename itself changes nothing a customer can measure. What changed underneath it does.

What Actually Shipped Today

The new Copilot app organizes around three sections. Home combines chat with Microsoft's Cowork agent and now embeds full versions of Word, Excel and PowerPoint, so a document can be drafted and edited without switching apps. Code lets a non-developer describe a tool or dashboard in plain language and have Copilot build it, using the same underlying technology as GitHub Copilot inside a sandboxed, tenant-hosted environment.

Autopilot, the renamed Scout, is a persistent agent with its own identity that runs inside Teams and Outlook while a person is away, following up on tasks without repeated prompting. Microsoft is also letting customers pick which model answers a given request, choosing between OpenAI's GPT, Anthropic's Opus, or an automatic router, a move Nadella linked directly to vendor independence.

The Number Behind the Relaunch

Microsoft's own numbers explain the urgency. In July 2026 the company reported 30 million paid Copilot seats against roughly 450 million commercial Microsoft 365 seats worldwide, a penetration rate under 7 percent after more than two years of marketing the product. OpenAI and Anthropic have spent the same period selling their own combined chat, coding and agent tools directly into the same enterprise accounts.

None of these figures require the rename to be true. Microsoft could have shipped the same Home, Code and Autopilot structure under the existing Copilot and Scout names and the underlying adoption problem would read exactly the same.

The Billing Line Nobody Highlighted

Today's announcement also confirmed a change to how Copilot gets paid for. Chat and the Office integration inside Home stay covered by the existing flat per-seat subscription, which Microsoft prices at 30 dollars per user per month in the United States and 30 pounds per user per month in the United Kingdom, on top of a qualifying base Microsoft 365 license. Code and Autopilot move to what Microsoft calls usage-based billing, a separate consumption charge layered on top of the seat fee.

Microsoft's own materials say administrators can set spending limits at the company, group or individual level. A spending cap is only a meaningful control when the default has no ceiling, which is exactly what a usage-based line item means: cost now scales with how much an agent actually does, not with how many people are licensed to use it.

The Decision Lesson

A rebrand costs a company nothing beyond a press release and a new set of icons. A change to how a product is billed costs whatever the meter runs to, and that number is not knowable in advance for a feature Microsoft itself has renamed twice before reaching broad preview. Finance and IT teams evaluating Autopilot should treat it as a variable-cost line from day one, not fold it into the flat per-seat budget line that Copilot chat has occupied for two years.

The same test travels well beyond Microsoft. Any vendor renaming a feature before it has shipped broadly is telling you something about how settled that feature is internally. Read what changed in the contract before reading what changed in the name.
