What did Microsoft announce on September 25, 2026?

Microsoft announced a redesigned Copilot built around three capability layers: Home, Code and Autopilot. Home is a unified starting point that merges the former Chat and Cowork experiences and embeds Word, Excel and PowerPoint so documents can be created and edited without leaving Copilot. Code lets users build apps, dashboards and automations from natural language, powered by GitHub Copilot technology and running in a sandbox inside the customer's own tenant. Autopilot — previously called Scout — is a persistent, cloud-hosted agent with its own identity, memory and workspace that executes multi-step workflows while the user is away. Home and Code roll out over the following weeks through Microsoft's Frontier program; Autopilot expanded to private preview at the end of September 2026.

What is Microsoft Autopilot and how is it different from Copilot chat?

Autopilot is a persistent cloud-hosted agent rather than a conversation. It has its own identity, its own memory and its own workspace, and it keeps executing multi-step workflows when the user is not present. Copilot chat is request-response inside your session and stops when you stop. The practical difference is that Autopilot can be assigned work that spans hours and survives you closing the laptop, which also means it needs to be governed like a service account, not like a chat window. Autopilot was formerly named Scout and entered private preview at the end of September 2026.

Is Microsoft Code the same as GitHub Copilot?

No — it is built on GitHub Copilot technology but aimed at a different user. GitHub Copilot lives in your editor and helps a developer write code in an existing repository. Copilot's Code tab builds whole apps, dashboards and automations from a natural-language description and runs them in a sandboxed environment inside your Microsoft tenant, which puts it closer to Lovable, Bolt or Replit Agent in intent and closer to Power Platform in governance. The tenant sandbox is the enterprise differentiator: output stays inside your compliance boundary.

When can I get Home, Code and Autopilot?

As announced on September 25, 2026, Home and Code begin rolling out over the following weeks via Microsoft's Frontier program, which is Microsoft's early-access channel for Microsoft 365 Copilot customers. Autopilot expanded to private preview at the end of September 2026, meaning invitation only. Microsoft did not publish general-availability dates or separate pricing for the three surfaces in the launch post.

Why did Microsoft rebuild Copilot now?

Competitive convergence. OpenAI fused Codex into the ChatGPT app in early July 2026, and Anthropic merged Cowork into Claude chat the week before this announcement. Satya Nadella had signalled in July 2026 that Microsoft was building an AI 'super app spanning both consumer and commercial experiences.' All three vendors arrived at the same structure — one surface containing chat, a coding agent and a background autonomous agent — within about ten weeks of each other, because the separate-apps model made users choose a product before they knew which one their task needed.

Quick Answer

What is the New Microsoft Copilot? Home, Code, Autopilot (Sep 2026)

Published: September 26, 2026

The short answer

On September 25, 2026 Microsoft replaced the Copilot app with three surfaces: Home, Code and Autopilot. Home merges Chat and Cowork and embeds Word, Excel and PowerPoint inline. Code builds apps, dashboards and automations from natural language in a sandbox inside your own tenant, using GitHub Copilot technology. Autopilot — the feature previously called Scout — is a persistent cloud agent with its own identity, memory and workspace that keeps working when you are not there. Home and Code roll out via the Frontier program; Autopilot went to private preview at the end of September 2026.

Home: the end of the Cowork/Chat split

Microsoft shipped Cowork as a separate collaborative surface and Chat as the assistant. Users had to know which one their task belonged to before starting it, which is a product-org boundary leaking into the UI. Home collapses them.

The genuinely new piece is Office inline. Word, Excel and PowerPoint are embedded in the Copilot experience, so a request that produces a document produces an editable document in place rather than a download or a link that opens another app. For the “summarize this and put it in a deck” workflow — which is most of what Microsoft 365 Copilot is actually used for — that removes the step where the handoff loses fidelity.

Anthropic made the same move the week before, merging Cowork into Claude chat. See what changed when Claude Cowork merged into Claude. The convergence is not coincidence; it is two companies discovering the same thing from telemetry.

Code: app-builder with a tenant boundary

Code takes a natural-language description and produces apps, dashboards and automations, running in a sandboxed environment inside the customer’s own tenant.

The capability is familiar — this is the Lovable / Bolt / Replit Agent shape. The tenant sandbox is the part enterprises will care about. Output and execution stay inside the Microsoft 365 compliance boundary, which means the data an internal dashboard touches never leaves, and the governance story routes through controls IT already operates. That is a materially different sell from “paste your data into a startup’s cloud IDE,” and it is the same argument Power Platform has made for a decade, with a better front end.

The open questions Microsoft did not answer on September 25: what the generated apps deploy onto, how they are licensed at scale, and whether Code output is governed under Power Platform policy or something new. Those determine whether this is a shadow-IT accelerator or a controlled one.

Autopilot: the one that changes your security model

Autopilot is the announcement with operational consequences. A persistent, cloud-hosted agent with its own identity, its own memory and its own workspace that executes multi-step work while you are not watching is not a feature of a chat app. It is a non-human principal in your directory.

That means the governance questions are directory questions, not AI questions:

What does its identity have access to? An agent with a standing identity accumulates permissions the way service accounts do — by accretion, never reviewed.
Who is accountable for its actions? FTC Chairman Andrew Ferguson, at Reuters Momentum AI Austin in late September 2026, pushed back on treating AI agents as autonomous actors and argued the party that instructed the tool bears responsibility. For Autopilot, that is whoever assigned the workflow, and by extension their employer.
What is its egress boundary? The relevance is immediate: OpenAI disclosed on the same day, September 25, 2026, that its agents had posted 53 ChatGPT user images to third-party hosts and generated close to a million encoded links. See that disclosure explained.
What does its persistent memory retain, and for how long? Memory that survives sessions is a data-retention surface subject to the same rules as a mailbox.

Private preview is the right stage for this. Treat the preview as a governance pilot rather than a productivity pilot: the interesting output is your answer to the four questions above, not the workflows it completes.

Why everyone shipped the same thing in ten weeks

Vendor	Move	Date
OpenAI	Codex fused into the ChatGPT app	Early July 2026
Microsoft	Nadella signals an AI “super app” across consumer and commercial	July 2026
Anthropic	Cowork merged into Claude chat	Mid-September 2026
Google	Antigravity agent tools brought into the Gemini API and AI Studio	September 2026
Microsoft	Copilot rebuilt as Home / Code / Autopilot	September 25, 2026

The shared insight: users cannot pick the right product before they understand the task, so making them pick costs you the task. One surface, three modes, with the background agent as the differentiator — because chat is commoditized and unattended execution is not.

Head-to-head analysis of the background agents is in Microsoft Autopilot vs ChatGPT agent mode vs Claude Cowork vs Google Antigravity.

What to do now

Microsoft 365 Copilot customer: get into Frontier for Home and Code. The Office-inline change alone affects daily usage more than any model upgrade this year.
Considering Code: ask your account team what the generated apps deploy onto and which policy engine governs them, before anyone builds something load-bearing.
Considering Autopilot: request private preview, then run it as an identity-governance exercise. Scope its directory identity narrowly, log all egress, set a memory-retention policy, and name a human owner per workflow.
Not a Microsoft shop: the pattern still applies. Every vendor is shipping a persistent agent with its own identity in Q4 2026. Get your non-human identity policy written before the tool arrives, not after.

Last verified: September 26, 2026. Home and Code availability is “rolling out in the coming weeks” via Frontier; Autopilot is private preview. No GA dates or separate pricing were published.
