Microsoft Copilot or Claude? How to choose an AI tool for your team

Microsoft Copilot or Claude for your team? A plain comparison based on the tools you already use, and how to train non-technical staff on either one.

If your email runs through Outlook and your files sit in SharePoint, start with Microsoft Copilot. If you work in Gmail, Google Drive, Slack or a mix of apps, start with Claude and its Cowork mode. The rest of this post explains that rule, where it breaks, and what training on each tool looks like.

The quick version

Three questions to answer first

1. Where does your email and file storage live? Microsoft 365 points toward Copilot. Google Workspace or a mixed setup points toward Claude, which connects to a range of apps instead of one suite.
2. What does a typical task look like? Rewriting a paragraph in Word is a different job from "pull last quarter's numbers from three files, compare them, and write a one-page summary."
3. Who will use it? Ten people drafting emails need something different from two people doing monthly analysis.

Microsoft Copilot

Copilot appears inside programs your staff already have open:

• Outlook: summarizes a long thread and drafts a reply.
• Word: drafts from an outline or from documents you point it to.
• Excel: explains a dataset, suggests formulas, builds summaries.
• Teams: recaps a meeting and lists action items.

Staff who are wary of AI don't have to learn a new app, because the Copilot button is in the Word ribbon.

Sort out licensing and permissions before rollout. Microsoft sells more than one version of Copilot, and what it can read (company email, files and meetings, or only text you paste in) depends on your licenses and your Microsoft 365 permissions. Copilot can surface any file a user already has access to, so if a shared folder is open to the whole company, Copilot will show its contents to anyone who asks. Ask your IT provider to review permissions first.

Claude and Claude Cowork

Claude handles long, messy material well: a 40-page contract, a stack of meeting notes, a long customer thread. Its writing needs less cleanup than most tools.

Cowork changes how you hand off work. You describe the result you want, and Claude plans the steps and works through them. You can point it at a folder or connect Gmail, Google Drive, Slack or your calendar, and it returns a document, spreadsheet or summary for review. It shows each step, so you can stop it and redirect.

Example requests:

• "Read these five vendor proposals and build a table comparing price terms, timelines and exclusions."
• "Go through this week's customer emails and list every open request, who sent it, and what they need."
• "Take this spreadsheet export and summarize what changed since last month."

Claude runs in its own app, outside Word and Outlook. Some teams like having a separate workspace for bigger jobs. Others won't open another window.

Using both

Some companies give Copilot to everyone for drafting inside Microsoft apps and give Claude to two or three people who do research and reporting. Before you pay for both, name who uses each one and for what.

Here is how that split could look. A 30-person distributor runs on Microsoft 365. Its customer service reps spend hours a week reading long email threads and writing replies, and the owner and controller lose a day each month assembling a sales summary from several exports. Copilot in Outlook fits the reps. Claude Cowork fits the monthly summary, since it can read all the exports at once.

Training after the purchase

A common rollout goes like this: the company buys licenses, sends everyone a login link, and three months later two people use the tool. Nobody showed the rest of the staff which parts of their own job it could handle.

I build AI training around your team's tasks. In a workshop, people work on their own documents, spreadsheets and email in the tool you chose. Each person leaves with three or four tasks they will hand to AI that week, and a list of outputs they need to check by hand.

I run sessions on-site around Rochester, Buffalo and Western New York, and remotely for teams anywhere else.
