Microsoft Just Reinvented Copilot: Here’s What Changed on September 25, 2026

Microsoft Copilot is about to become much more than an AI chatbot.

On September 25, 2026, Microsoft announced a major redesign of Copilot, bringing together AI chat, Office, app creation and autonomous AI agents in one experience.

The announcement introduces three major parts: Home, Code and Autopilot.

And the idea behind them is simple: instead of only asking Copilot questions, users will increasingly be able to give it work to do.

Copilot Gets a New Home

The first major change is simply called Home.

It becomes the new starting point for Copilot, bringing different ways of using the AI together in one place.

Users can chat with Copilot as before, but they can also use Cowork to delegate more complicated jobs.

Instead of saying:

"Summarize these documents."

You could give Copilot a bigger objective and let it work through the different steps.

Microsoft gives examples such as preparing an RFP response, creating a launch package, preparing a customer briefing or putting together a financial close package.

The interesting part is that Microsoft says Copilot will eventually be able to decide whether a request is better handled by Chat, Cowork or Code.

In other words, users shouldn't have to worry about which AI tool they need.

They simply explain what they want.

Word, Excel and PowerPoint Are Coming Into Copilot

Microsoft is also bringing the full power of Word, Excel and PowerPoint directly into Copilot.

This means Copilot can create and edit actual Office files rather than simply producing text that you have to copy somewhere else.

You could ask it to:

• Create a Word document
• Build an Excel budget
• Create a PowerPoint presentation
• Continue working on an existing file
• Modify a document that your team is already using

The files remain editable and can continue to be worked on in the normal Office applications.

Microsoft also highlights improvements to PowerPoint and Excel. PowerPoint can help keep presentations on-brand, while Excel makes it easier to see exactly what Copilot changed and recommends charts for your data.

The goal is obvious: less copying and pasting between AI and Office.

Copilot Code Lets You Build Apps by Describing Them

This may be one of the most interesting parts of the announcement.

Microsoft is introducing Copilot Code, which allows people to create their own small applications and tools without necessarily being traditional programmers.

You can describe what you want in normal language.

For example:

"Create a dashboard that shows my website traffic."

Or:

"Build a project tracker for my team."

Or:

"Create a tool that helps me compare these products."

Copilot can then choose an approach and build the solution.

Microsoft says Code can create things such as dashboards, trackers, automations, workflows and internal applications.

It is powered by technology also used by GitHub Copilot and runs in a sandboxed environment.

That could make AI-generated applications much more accessible.

You no longer necessarily need to start with:

"How do I code this?"

You can start with:

"What do I want this tool to do?"

Meet Autopilot

But the biggest surprise may be Autopilot.

Autopilot is designed to work more like a digital employee than a traditional chatbot.

You give it a name, role and goal.

Then it can continue working without waiting for you to send another prompt.

Microsoft says Autopilot can monitor channels, follow up on conversations, handle recurring work and return to projects later.

For example, imagine a company needs to conduct a supplier review.

Instead of asking Copilot to perform every individual step, Autopilot could help organize the process, prepare meetings, follow up with people and request information from stakeholders.

And because it is cloud-hosted, it can continue working while you are away from your computer.

That's a very different concept from asking an AI chatbot a question.

Copilot Can Understand More of Your Work

Microsoft is also expanding Microsoft IQ, the technology used to give Copilot more context about an organization.

The idea is that Copilot should understand more than just the question you typed.

It can work with information from Microsoft's business ecosystem, including data from Power BI, Dynamics 365 and Power Platform.

For example, when preparing a sales proposal, Copilot could potentially use information about previous deals and customer support history without forcing the employee to search through different applications manually.

The more context Copilot has, the more useful its answers and actions can become.

Copilot Can Connect to More Tools

Microsoft is also introducing a new plugin registry.

Plugins allow Copilot to connect to additional tools, services and capabilities.

Instead of having dozens of separate AI integrations, Microsoft wants organizations to have a central place where these capabilities can be discovered and managed.

IT departments will also be able to control which plugins are approved for use.

For users, this could eventually mean that Copilot can perform more tasks without leaving the applications they already use.

Microsoft Is Also Thinking About the Cost

All these new capabilities raise an obvious question:

How much will this cost?

Microsoft is introducing new tools for managing AI spending, called FinOps for AI.

The company is separating everyday Copilot usage from more demanding AI work.

Normal activities such as asking questions, creating drafts and getting summaries are covered by the regular user subscription model.

More intensive features such as Cowork, Code and Autopilot use usage-based billing.

For businesses, this means AI spending can be monitored and controlled rather than simply allowing every AI feature to run without limits.

What Comes Next?

Microsoft says the September 25 announcement is only the beginning.

One of the next features is Today, a more proactive Copilot experience designed to look across emails, calendars, Teams conversations, meetings and tasks.

Instead of waiting for you to ask what needs attention, it could highlight what you missed, what needs action and what can wait.

Microsoft plans to begin private preview of Today in October 2026.

Microsoft is also working on a new Teams experience where Copilot can understand the shared context of a channel, group chat or meeting.

So, What Actually Changed?

The biggest change isn't one individual feature.

It's the way Microsoft is thinking about Copilot.

The old idea was simple:

Ask Copilot → Get an answer.

The new idea is much broader:

Tell Copilot what you want to accomplish → Let it help plan, build and execute the work.

Home brings everything together.

Code lets users build their own tools.

Autopilot can continue working on its own.

Cowork can handle larger tasks.

Microsoft IQ gives Copilot more context.

And Office is being brought directly into the experience.

Microsoft announced all of this on September 25, 2026, with Home and Code beginning to roll out through its Frontier program and Autopilot entering private preview at the end of the month. Availability will therefore vary, and not every feature is immediately available to every Copilot user.

Copilot is no longer being presented simply as Microsoft's answer to ChatGPT.

Microsoft is trying to turn it into something much bigger: An AI workspace that can understand your work, build tools and actually get things done.
