Once a team gets comfortable with Copilot, a natural question comes up: is there a step up for the heavier thinking work — the long analysis, the dense document, the thing you really want to get right? Often, yes — and that’s where Claude comes in. Here’s the part that surprises people: it’s not an either/or with Copilot anymore. Claude now lives inside Microsoft 365 Copilot through the model picker, so you can reach for it without leaving the tools you already use.
What is Claude good at?
Think of it as the tool you reach for when the task is less “draft this quick email” and more “help me think this through.” It’s strong with long, complex documents — feed it a 40-page contract, a detailed RFP, or a year of meeting notes and ask it to find the risks, summarize the obligations, or pull out what changed. It’s strong at careful writing and reasoning: a board memo you want genuinely tight, an analysis where the logic has to hold up, a tricky client email where tone is everything. It handles a lot of context at once and tends to stay measured and clear rather than overconfident — which matters when the stakes are real.
The way I think about it: Copilot is the on-ramp; Claude is the power tool. Copilot is where your team starts, in the flow of daily work. Claude is what you reach for when a task deserves more careful thinking — and increasingly, you reach for it from inside Copilot, picking the model that fits the job.
How to get the most out of it
- Start where the thinking is hardest. Don’t move your quick emails to Claude — keep those in Copilot. Bring Claude the long document, the messy analysis, the high-stakes memo. That’s where the difference shows.
- Give it room to reason. Claude does well when you ask it to think out loud: “Walk through the risks in this contract, then summarize the three I should worry about most.” You’ll get sharper output and you can follow its reasoning.
- Use the model picker in Copilot. Because Claude is available inside Microsoft 365 Copilot, your team can stay in one place and just pick the right engine for the task — no new login, no new habit to build.
- Mind what you share, as with any tool. When you use Claude inside Microsoft 365, it runs under your existing controls — which is exactly why that’s the right place for business information. Treat that as enablement: it’s how you get the heavy-lifting tool and keep your data handled properly.
You don’t have to choose a side in the AI tool wars. The teams getting the most out of this use Copilot as their daily driver and reach for Claude when a task deserves a deeper engine — often without ever leaving Microsoft 365, under the controls you already have. Start with one hard document this week and feel the difference.
Claude does its best work on a foundation of Microsoft 365 and Copilot, set up right. Curious where it fits alongside your rollout? Let’s map it to your real work.
