Microsoft’s Copilot Super App Chases Its Own 450M Base

Microsoft is building a Copilot super app that pulls its scattered AI tools onto a single screen, a project first reported on May 29 by Fortune’s Sebastian Herrera, a tech correspondent, and confirmed by tech journalist Alex Heath, who published a leaked screenshot of the interface. The hub would fold together Copilot chat, the GitHub Copilot coding assistant, the Copilot Cowork agent, a new workflow engine codenamed Autopilot, and a proactive agent called Scout. Microsoft is aiming to ship it by the end of summer.

Lined up next to OpenAI and Google, the move looks like a sprint for consumer attention. The more revealing number sits inside the same reporting: Microsoft already sells a vast Microsoft 365 base and still cannot persuade most of those customers to pay for Copilot.

The Apps Microsoft Is Folding Into One Copilot

Today a customer who wants to chat, write code, and hand a task to an agent has to jump between separate apps and separate sign-ins. The unified hub is meant to stop that jumping. Herrera reported that the project runs under the internal slogan Delivering one Copilot, with a toggle that lets people switch between personal and work accounts without leaving the app. Microsoft has built much of its paid pitch around the enterprise assistant described in its official Microsoft 365 Copilot overview, and the company says the individual Copilots will still work on their own for anyone who prefers them.

Here is what the reporting and the leaked screenshot put inside the single app:

• Copilot chat, the consumer-facing assistant most people already tie to the Copilot name.
• Microsoft 365 Copilot, the productivity version that lives inside Word, Excel, Outlook and Teams, recently rebuilt for deeper in-app use (see our coverage of the redesigned Microsoft 365 Copilot workspace).
• GitHub Copilot, the coding assistant for developers.
• Copilot Cowork, an agent built to take on multi-step tasks.
• Autopilot, a new agentic workflow capability still under an internal codename.
• Scout, a proactive agent surfaced in the leaked screenshot and not previously reported.

Why 450 Million Seats Outrank the Consumer Headlines

Strip away the super app framing and you find a conversion problem. Microsoft sells its Office suite to a huge paying base, yet fewer than 4.5% of those customers pay extra for Copilot, according to the figures in Herrera’s report. That leaves under 20 million Copilot seats sitting on top of an installed base more than twenty times larger.

The scale of the gap is the actual story:

• 450 million Microsoft 365 seats form the base Microsoft is trying to convert.
• Under 4.5% of those seats pay for Copilot today.
• 4.7 million developers pay for GitHub Copilot, where Pro plans start at $10 a month, per GitHub Copilot’s paid plans.

Microsoft’s own diagnosis, relayed through people briefed on the plan, is that the tangle of separate Copilots is part of the problem. The redesigned Office assistant already lifted usage inside Word and Excel; the super app extends that logic to the whole product line.

Microsoft has found that customers dislike shifting between its Copilot tools, and the company also seeks for people to see more value from Copilot.

Those words came from sources briefed on the project and quoted by Fortune, not from Microsoft, which declined to comment.

Jacob Andreou and the Consumer Growth Playbook

The person running this is Jacob Andreou, who became Microsoft’s Executive Vice President (EVP, the senior leadership tier reporting to the chief executive) of Copilot this spring. He joined Microsoft in 2025 after eight years at Snap, where he ran product and growth, with a stint as a venture investor at Greylock in between. He now reports directly to Satya Nadella, Microsoft’s chairman and chief executive.

Microsoft’s March Copilot leadership update handed Andreou design, product, growth and engineering for Copilot across both the consumer and commercial sides. That is an unusual mandate, and a deliberate one. Microsoft picked a consumer-growth specialist to fix a product that has to win over individual users and cautious enterprise buyers at the same time.

The super app also fits a second shift. Microsoft has spent the past year loosening its dependence on OpenAI, the startup it bankrolled early. It added Anthropic’s Claude models as an option inside Microsoft 365 Copilot and kept building its own in-house models, several of which are expected to surface at its developer conference next week. A unified app gives Microsoft a single front door it controls, whatever model sits behind it.

The Super App Race: ChatGPT, Gemini and Copilot Compared

Microsoft is not moving in a vacuum. OpenAI is building what it calls an AI superapp around ChatGPT, its Codex coding tool and agents, while Google has folded more of its products into Gemini. The competitive picture is lopsided on raw reach.

On mindshare, Copilot trails badly. ChatGPT reached 900 million weekly active users in February 2026, roughly double its total a year earlier, and Google’s Gemini sits in the same range on a monthly basis. Microsoft has never published a comparable Copilot figure, which itself says something about where it stands.

Where the One Copilot Plan Could Stall

The plan is not final. Herrera’s sources cautioned that the design could still change before release, and Microsoft has shipped, and shelved, unified consumer products before. Several things have to break the right way.

The harder problems cluster in four places:

1. The toggle. Merging personal and enterprise Copilots means merging two very different data-governance regimes, and IT departments are strict about where corporate data flows.
2. GitHub Copilot’s identity. Developers chose it as a focused coding tool, and some may resist being routed through a broader consumer app.
3. Mobile reach. A super app lives or dies on phones, and Microsoft has no strong consumer mobile foothold to match Google’s Android or Apple’s iPhone defaults.
4. One more door, not fewer. Microsoft keeps launching standalone Copilots, including a recent Copilot Health preview, so the new hub has to absorb that sprawl rather than add to it.

Each of these is a reason the target could slip, or the launch could land softer than the ambition suggests.

Build Keeps Quiet as the Summer Launch Looms

Microsoft’s Build developer conference opens next week in San Francisco, and the super app will not be on stage. Herrera reported the company plans to keep the app itself out of the keynote, though pieces of the one Copilot idea may get airtime. The official Build 2026 schedule leans heavily on agents and developer tooling, and our own Build 2026 preview noted the event skips the usual Windows and hardware reveals.

The real test comes later. If the toggle between personal and work Copilot is clean enough that those Office users finally see one assistant worth paying for, Microsoft can convert the base it already owns. If it feels like the same scattered tools behind a new icon, the super app becomes one more entrance to a product people still struggle to find a reason to buy.
