Claude gains shared context in Excel, PowerPoint; Microsoft adds Copilot Cowork
Anthropic’s latest update lets Claude carry information from one Microsoft document into another, meaning a prompt you craft in Excel can be recalled when you switch to PowerPoint without re‑typing. The move hints at a broader push to make generative assistants feel less like isolated chat windows and more like collaborative teammates that remember the workflow you’re building. For businesses that juggle spreadsheets, slide decks, and countless internal reports, a single context thread could shave minutes—or even hours—off routine tasks.
That ambition aligns with what Microsoft announced on Monday: a new Copilot Cowork feature that lets enterprise users spin up agents capable of acting across the same suite of apps. The tech giant explicitly said the capability was co‑developed with Anthropic, which rolled out its own version of shared‑context functionality at the same time.
Similarly, Microsoft's new Copilot Cowork capability introduced on Monday enables enterprise users to deploy agents to complete tasks across Microsoft applications such as Excel and PowerPoint.

Similarly, Microsoft's new Copilot Cowork capability introduced on Monday enables enterprise users to deploy agents to complete tasks across Microsoft applications such as Excel and PowerPoint. The software giant openly stated it was built in conjunction with Anthropic, which also released its own stand-alone Claude Cowork application for Mac and Windows earlier this year offering a way for Claude to access, edit, create and move information between files on a user's computer, autonomously, at the user's direction. Previously, even with autonomous tools like the standalone Claude Cowork app, users often had to ask the AI to complete tasks in separate steps for each application.
Claude now talks to Excel and PowerPoint. Users can reuse prompts across the two apps. The add‑ins launch today on paid Claude plans for both Mac and Windows.
Anthropic says the move expands its enterprise reach, but whether organizations will favor Claude over Microsoft’s own Copilot Cowork remains unclear. Microsoft introduced Copilot Cowork on Monday, letting agents hop between Excel, PowerPoint and other Microsoft tools. The company noted the feature was built together with Anthropic, the same firm behind Claude’s new add‑ins.
This overlap blurs the line between partner and competitor. Both firms are betting on shared‑context agents to streamline workflows, yet adoption metrics are not yet public. Early feedback from pilot customers suggests modest productivity gains, but broader impact is still being measured.
Enterprises will have to weigh licensing costs, integration effort and the promise of cross‑application continuity, while also considering internal security policies and the need for staff training on new AI agents. As the two offerings sit side by side, the market will likely see a period of testing and comparison before any clear leader emerges.
