Word, Excel and PowerPoint open inside the Copilot app for Frontier users

On 9 October 2026, Sumit Chauhan posted on the Microsoft Copilot Blog that Word, Excel and PowerPoint now sit inside the new Copilot app. The post says you start in Chat or Cowork, get a draft, and keep editing in the same place, including if you later open the file in the standalone Office apps. The page is marked updated the same day.

The worked example is a Word file. A prompt such as the one in the post, asking for a customer-ready launch brief, produces a document that opens beside the conversation. The chat history stays, so a follow-up can ask for a more direct opening or a comparison table. The post says the canvas also has the usual editing controls, and that the same path covers spreadsheets and presentations. It says you can pick a model for the task or let Auto choose. It does not name the models.

The file is an Office file

Microsoft’s account of collaboration is the ordinary Office set, inside that view: sharing, comments, co-authoring and presence, with edits from you or someone else shown as they happen, in one file. Library lists recent Word, Excel and PowerPoint files, plus pages and images made in Copilot or in the Office apps, and can start a new document, spreadsheet or presentation. Storage is OneDrive. The post says files keep formatting, comments, sharing permissions and version history, and pick up the security labels, compliance and governance controls the organisation already uses.

Further down, the post describes Copilot behaviour it says is also arriving for Office in the app. In PowerPoint, that is keeping a deck on brand, editing slides and images, and applying custom templates. In Excel, it is reviewing edits Copilot made, seeing what changed, and chart suggestions. Skills and connectors are the examples it gives for specialised work, financial analysis in Excel and legal workflows in Word, and for reusing a role’s setup across a company. Those are Microsoft’s descriptions of the product. The post does not include a test, a customer count or a date when each of those pieces finishes rolling out.

Who can open it, and what it costs

The last line of the post is the availability statement: “Office in Copilot is rolling out today for Frontier customers in Chat and Cowork.” The post does not define Frontier, does not give a date for everyone else, and does not list a price.

Three weeks earlier, on 26 September, AFP’s report carried by TechXplore described the same direction before this rollout note. Jacob Andreou, a Microsoft executive vice president for Copilot, told AFP: “Many people have put simplified document viewers into their products over the course of the last year. But this is full-blown Office.” AFP wrote that, in the coming weeks, individual Microsoft 365 subscribers and businesses in a testing program would create, edit and share files in Copilot without switching apps. The 9 October post is narrower on who gets it now: Frontier customers, in Chat and Cowork.

The $30 figure is from that September story, not from the October post. AFP reported that a Copilot subscription at $30 per user per month covers basic AI features such as data analysis or drafting, and that Andreou called that the tier to give to everyone in a company. The same article says advanced agents, which use more compute, are billed by usage. Nothing on the 9 October page ties Office-in-Copilot to that price, or to any other one.
