Microsoft rebuilds Copilot as a three-tab 'super app' with a Code builder and a persistent Autopilot agent

Microsoft is done treating Copilot as a chat window. On Friday, the company unveiled a redesigned Copilot app organized around three tabs — Home, Code, and Autopilot — alongside Office apps embedded directly in the experience and new FinOps tooling for tracking AI spend. CEO Satya Nadella described the update on X as a new "OS for work."

The headline for developers is the Code tab: a natural-language app builder that lets users describe an app, dashboard, or workflow and get working software back, powered by what Microsoft says is the same underlying technology as GitHub Copilot. Tasks started in Code also sync with the standalone GitHub Copilot service, so work begun in the Copilot app carries over to the developer's normal toolchain. Code starts rolling out through Microsoft's Frontier early-access program at the end of September, with a preview for Microsoft 365 Premium and Pro subscribers later this year.

Home merges the Chat and Cowork experiences into a single starting point, and it's where the new Office in Copilot integration lives: Word, Excel, and PowerPoint run inside Copilot itself, producing real, editable documents rather than exports. Copilot can draft a launch brief, model a budget, or build a deck while teammates edit live — @mentioned collaborators' changes appear as they happen. Microsoft says PowerPoint now keeps generated decks on-brand automatically, Excel shows exactly what changed and why when Copilot or a collaborator edits, and a new Skills feature brings role-specific workflows (financial skills in Excel, legal skills in Word) into the 365 apps.

Autopilot is the new name for Scout, the long-running agent Microsoft has been testing for months — Directions on Microsoft describes it as an OpenClaw-based agent — and it's the biggest behavioral shift in the package. Rather than waiting for a prompt, Autopilot is persistent and proactive: it carries its own identity in the company directory, holds specific permissions the user controls, and keeps working on delegated tasks after the person has logged off. Microsoft is pitching it as a "digital coworker" for the enterprise, with Annie Pearl, corporate VP of Copilot Product, telling Reuters the design priority was making agents deployable under enterprise security, compliance, and governance constraints. Autopilot moves to private preview at the end of September.

Underpinning all of it is FinOps for AI, Microsoft's answer to the runaway-spend anxiety that comes with handing agents real work. Admins get spending policies at scale with API access, can route end-user credit requests into existing approval workflows, and can set which model families are available to different groups — controls that also shape what Copilot's automatic model selection can choose. The announcement also brings a public preview of the Copilot Managed Runtime hosting platform and expanded grounding on business data.

One clarification worth making, since the naming is now genuinely confusing: this Autopilot is not the autopilot mode in GitHub Copilot and Copilot CLI that lets agents run to completion without asking permission. Microsoft's is the 365-side persistent agent; GitHub's is a per-session permission mode. Two products, one overloaded word.

The rollout is deliberately staged — Home and Code reach Frontier users "in the coming weeks," and Microsoft says that soon users won't pick a mode at all: you'll state the outcome you want and Copilot will route the work to Chat, Cowork, or Code itself. The engineering overhaul behind this took six months and follows August's merge of the consumer and commercial Copilot apps. Whether the super-app framing sticks depends on the part Microsoft can't ship in a blog post: getting enterprises comfortable letting a persistent agent with a directory identity loose on real work.
