Which AI Assistant fits the way you work?

Why Microsoft 365 Copilot fits every day work

A plain-English guide for people trying AI at work: what Copilot does, how it differs from a separate assistant such as Claude and where to start.

The short answer

Claude is a separate AI workspace. Copilot sits inside the Microsoft apps many teams already use and can work with the emails, files and meetings each person is allowed to access. 

A separate assistant helps when:Copilot helps when:
– You need help creating or developing content from scratch.

– The task is focused research, reasoning or code.

– The answer does not depend on your work content.
– You already have emails, files, meetings or messages related to the task.

– The answer depends on your work content.

– You want to work in the app where the result will be used.

Four useful differences from day one

1. Works where you do

Use Copilot in Word, Excel, PowerPoint, Outlook and teams.

2. Uses your work context

Find answers from the content your account is already allowed to open.

3. Moves the task on

Draft, summarise and follow up without rebuilding the context from scratch.

4. Keeps existing controls in place

Your Microsoft 365 permissions and company controls continue to apply.

Where to start?

Choose one habit for the first week: catch up on your inbox, recap a meeting or draft a document from existing files. Then build from there.

Copilot and Claude in everyday terms

Both can help with demanding work. The practical difference is where they sit in your day and how much context you have to provide before they can help.

Best fitUseful for focused tasks where a separate workspace suits the job.Useful when the work already sits in Microsoft 365.

Tip: You do not have to make one AI tool do every job. Copilot adds Microsoft 365 context and in-app working to the mix.

Four things to try straight away

You do not need to master prompting first. Start with a familiar task, name the source and say what you want back.

1. Inbox Catch-up

“Summarise the emails I have not read since yesterday. Group them by topic and list anything that needs a reply from me.”

Copilot can work from mail your account can access, so you get a focused catch-up without copying messages into another tool.

The difference: the context is already in Outlook.

2. Meeting recap

“Recap this meeting. List the decisions, actions and anything I agreed to do.”

Where a recap or transcript is available, Copilot can pull the discussion into a usable list of decisions and actions.

The difference: you do not have to recreate the meeting context.

3. First Draft

“Draft a one-page customer update using this proposal and last week’s notes.”

Copilot can use the files you name and create the first draft in the app where you will edit it.

The difference: you start with a working file, not a blank page.

4. Email coaching

“Review this email. Is the request clear, and could any wording be misread?”

Copilot can suggest changes inside the draft. You decide what to keep.

The difference: the review happens where you will send the message.

Tip: Say what you want. Name the email, meeting, file or people. Then describe the output.

What people ask before they start

Straight answers to the questions that come up when a team is deciding how Microsoft Copilot fits alongside a separate AI assistant.

1. Is Claude better at writing?

For a blank-page task, preference is personal. Work rarely starts from a blank page, though. It usually depends on an email thread, a proposal or a meeting. Copilot’s advantage is its connection to that context.

Try this: give both tools the same permitted source material and compare the result.

2. Can I keep using Claude too?

Yes. One tool does not need to cover every task. Anthropic models are also available in selected Microsoft Copilot experiences when your administrator enables them.

Try this: agree which tool is used for which kind of work.

3. What can Copilot meeting see?

Copilot works within the permissions attached to your Microsoft 365 account. If you cannot open a file or message, Copilot should not use it as your work context.

Try this: review sharing and permissions before a wider rollout.

4. Do I need to learn prompting?

No. Plain requests work. You will get a better first answer when you name the source, the people involved and the format you want.

Try this: reuse the four prompts on the previous page for a week.

5. Will it save time?

It is most useful when you attach it to regular work rather than treating it as an occasional experiment. Start with a small number of repeatable tasks and check the result.

Try this: choose two recurring tasks and compare the old and new process.
