Three Tabs to Rule Them All: Microsoft Reboots Copilot as a Chat-Code-Agent 'Super App'

After teasing a Copilot “super app” at the end of July and folding its consumer and commercial Copilot apps into one last month, Microsoft made it official today: the Copilot app is now a single three-tab interface — Home, Code, and Autopilot — that merges AI chat, coding, and autonomous agents into one product. Along the way, the company rebranded Scout, the AI personal assistant it unveiled at Build earlier this year, as Autopilot. It is the most coherent redesign Copilot has had since the assistant first appeared as a chatbot inside Bing, and it lands at a moment when Microsoft badly needs one.

The stakes are easy to state and hard to overstate. Of more than 450 million commercial Microsoft 365 seats worldwide, fewer than 7 percent carry a license for the $30-per-user-per-month Microsoft 365 Copilot add-on. Meanwhile Anthropic’s Claude has been gaining real traction in enterprise knowledge work, OpenAI and Anthropic bundle multiple capabilities into easy-to-use products, and Meta’s Muse app — launched earlier this month — shot to the top of Apple’s App Store. Microsoft’s shares are up just 3 percent this year, underperforming the Nasdaq and most of its megacap peers. The new Copilot app is the company’s answer to all of it, positioned explicitly as “the AI built for work.”

Home: one place to get your bearings

Home is the new default landing experience, combining what used to be two separate modes: Chat and Cowork. Chat handles the instant, conversational layer — quick questions, lookups, drafts. Cowork is for delegated work: you define a task and it runs end-to-end, returning a completed RFP response, launch kit, customer briefing, or financial close package. A planned “Today” view inside Home acts as a personalized dashboard for important emails, meeting requests, and Teams threads. And in a coming update, users won’t pick the mode at all — Copilot will route work to Chat, Cowork, or Code automatically based on what you ask for.

The bigger news inside Home is Office in Copilot. The full power of Word, Excel, and PowerPoint is now built directly into the app: ask for a launch brief, a budget model, or a deck, and Copilot creates a real, editable document, workbook, or presentation — live for your whole team, not a chat artifact you have to copy-paste and reformat. @mention a teammate and their edits appear as they make them; the file stays in sync between Copilot and the Office apps. Microsoft has also sharpened the in-app experiences: PowerPoint keeps decks on-brand automatically, Excel shows exactly what changed and why when Copilot edits a formula or chart, and role-specific “Skills” bring financial and legal expertise into the apps.

Code: GitHub Copilot’s engine, for everyone

The Code tab is the surprise of the launch — a coding surface inside an app aimed at knowledge workers rather than developers. “Code moves solution-building outside the realm of developers alone,” writes Jared Spataro, Microsoft’s chief marketing officer for AI at work. The unit of knowledge work has historically been the file — the document, spreadsheet, deck. Code adds a fourth category: small, purpose-built solutions anyone can create. Describe an app, tracker, dashboard, automation, or workflow in natural language and Copilot picks an approach and builds it, from persistent desktop widgets to cloud-hosted internal apps shareable with a team.

Under the hood, Code runs on the same underlying technology as GitHub Copilot, executes in a sandboxed environment, and can be hosted securely within a company’s tenant. A new Copilot Managed Runtime — hosting infrastructure that lets code run safely inside the Microsoft 365 environment, governed by IT — is now in preview and underpins apps built in Cowork, Code, and Copilot Studio, with Microsoft opening it to third-party and pro-code developers as well. Professional developers keep GitHub Copilot for their daily work, now with deeper connectivity into the Copilot platform.

Early customers see the appeal. David McLaren, enterprise data and AI leader at consulting firm GHD, which has deployed Copilot to 12,000 employees with about 200 experimenting with Cowork, told CNBC he is excited for the new app “because it makes GitHub-like capability simpler for more people to use.”

Autopilot: Scout grows into a digital teammate

Autopilot is the rebranded Scout — and the rebrand reflects a real product shift. Where Scout was initially a desktop app, Autopilot is cloud-hosted: give it a name, a role, and a goal, and it keeps working while you sleep. It watches Teams channels, follows up on threads, runs recurring work, and can pick a project back up days later without waiting for a prompt. Microsoft’s example is a full supplier review process: Autopilot builds the schedule and workback plan, handles prep, meetings, and follow-ups on its own, right down to reaching out to stakeholders for updates.

What differentiates it from the fast-growing field of consumer agents is the enterprise plumbing. Autopilot lives in your tenant with its own identity, memory, computer, and workspace. It surfaces in Teams, Outlook, chats, channels, and documents — you can @mention it like a colleague — with permissions, audit, and governance behind it. It is built on Microsoft IQ, the unified intelligence platform for enterprise AI across the Microsoft stack. Today Microsoft also expanded that context layer: Fabric IQ brings trusted context from data including the 20+ million semantic models in Power BI (generally available now for Chat and Cowork), Dynamics 365 and Power Platform data and workflows arrive in public preview over the next month, and a new plugin registry rolls out across surfaces in the coming weeks.

The billing model quietly says the most

Beyond the tabs, the most consequential change may be commercial. Rather than pure per-seat subscriptions, the Cowork, Code, and Autopilot portions of the new app will be billed based on usage — closer to how companies buy AI from OpenAI and Anthropic than how they’ve historically bought Microsoft software. The regular user subscription license still covers Copilot in Chat and across Word, Excel, PowerPoint, Outlook, and Teams. An auto model picker matches the model to each task, and IT admins get new FinOps for AI tooling to keep agentic spend from running away. Usage of frontier models like Astra and Fable will be metered — which makes the FinOps layer not a nice-to-have but a prerequisite.

Notably, CNBC reports that in the Code tab users can manually select which model to use, including a cost-efficient Microsoft offering — but in the Home tab, there’s no Microsoft model available at all. Microsoft is still leaning on OpenAI and Anthropic’s frontier models even as it invests in its own.

The catch-up framing is Microsoft’s own

Jacob Andreou, Microsoft’s EVP for Copilot, was candid with CNBC that adding coding to the app is an instance of Microsoft playing catch-up, and that “the problem is that these agents have been almost impossible to bring into the enterprise.” “We’re holding a very high bar,” he said. “This product is at its best when it’s just optimizing for user value and for the quality of the output and what it’s able to deliver.” Cost efficiency, he argued, is less important.

Satya Nadella, who first talked up the super app vision in June, framed the Frontier early-access program at a Seattle preview event this week as “not about any one frontier model… It’s about the frontier ecosystem,” where every firm can turn its human capital “in the flow of AI” into a continuous learning system.

Microsoft’s ambition is unambiguous. “Just as Office defined work for the PC era, the new Copilot is built to define it for the AI era,” Spataro writes. Home and Code start rolling out through the Frontier program in the coming weeks (Code reaches preview for Microsoft 365 Premium and Pro subscribers later this year), and Autopilot expands to private preview at the end of the month. The comparison to Office is bold — but as The Verge’s Tom Warren notes, the AI era has far more competition than the PC era ever did. Microsoft has fallen behind Google, OpenAI, Anthropic, and now Meta in consumer AI; whether “the AI built for work” is enough to win the enterprise is precisely the question this launch exists to answer.
