What is Claude and what is Copilot?
What is Claude?
Claude is Anthropic’s AI assistant, available via claude.ai and through API. It is known for long context windows of up to 200,000 tokens, nuanced writing, strong reasoning and a safety focused design.
Claude Sonnet 4 and Claude Opus 4.1 are the current flagship models in 2026. Claude is used for research, writing, analysis, coding and complex multi-step tasks.
What is Microsoft Copilot?
Microsoft Copilot is Microsoft’s AI assistant, built into Microsoft 365 apps including Word, Excel, Outlook, Teams and PowerPoint. It uses a range of models including GPT-4o and, increasingly, Claude.
Copilot is designed for workplace productivity and integrates directly with your existing Microsoft tools and data.
The key difference
Claude is a standalone AI model you interact with directly. Copilot is a platform that wraps AI models, including Claude, into your Microsoft 365 workflow.
They are not always competing products. In many cases, they work together.

How to use Claude inside Copilot
This is the detail most comparison guides miss. You do not have to choose between Claude and Copilot. Microsoft has integrated Claude directly into Microsoft 365 Copilot through two routes.
The Researcher agent
In the Microsoft 365 Copilot app, you can select Researcher under Agents in Chat and then select Claude. Claude Opus 4.1 powers the Researcher agent for complex, multi-step research tasks including deep research, trend analysis, report compilation and synthesising information across multiple sources.
See Microsoft’s official support page for step by step instructions.
Copilot Studio
You can also access Claude through Copilot Studio, Microsoft’s platform for building custom AI agents for enterprise teams. This allows organisations to build Claude-powered workflows inside their existing Microsoft environment.
How access works
Claude models including Claude Sonnet 4 and Claude Opus 4.1 are available through Microsoft’s Frontier Program to licensed Microsoft 365 Copilot customers who opt in. Organisation administrators can enable access through the Microsoft 365 admin centre.
Claude runs on Anthropic’s cloud accessed through Azure, so it works with existing Azure agreements and billing. See Anthropic’s announcement for full details.
Is Claude better than Copilot for writing and content?
Claude wins on long form and nuance
Claude handles long documents, complex briefs and nuanced tone better than standard Copilot. Its 200,000 token context window means it can read and respond to entire reports, contracts or research papers in one go.
For drafting, editing and summarising long form content, Claude is the stronger standalone tool.
Copilot wins on integration
Copilot drafts emails in Outlook, summarises meetings in Teams and rewrites documents in Word without leaving your workflow. For UK professionals already in the Microsoft 365 ecosystem, Copilot removes friction and saves time on everyday tasks.
Verdict for writing
Use Claude for complex, high stakes writing tasks where nuance and depth matter. Use Copilot for quick, integrated drafts inside Microsoft 365. Use both together via the Researcher agent for the best of both.
Is Claude better than Copilot for research and analysis?
Claude leads on depth
Claude Opus 4.1 is built for complex, multi-step research. It can synthesise large volumes of information, identify patterns and produce structured analysis. The Researcher agent inside Copilot uses Claude specifically because of this capability.
Copilot leads on connected data
Copilot can pull from your organisation’s SharePoint, Teams and Outlook data to surface relevant information. This connected context is powerful for internal research and knowledge management.
Verdict for research
For deep external research and analysis, Claude is stronger. For internal knowledge retrieval and connected data, Copilot has the edge. The Researcher agent combines both.
Is Claude better than Copilot for coding?
Claude leads on complex tasks
Claude Code handles multi-file refactors, test iteration and complex code generation with a massive context window. It is the stronger tool for agentic, terminal-first coding tasks.
Copilot leads on daily coding
GitHub Copilot offers inline autocomplete, broad IDE support across six or more IDEs and fast completions for everyday coding. It is the more practical tool for daily development work.
Verdict for coding
Developers doing complex, multi-file work will prefer Claude. Developers who want fast inline suggestions across IDEs will prefer GitHub Copilot. Many UK development teams use both.
Is Claude better than Copilot for UK pricing?
How much is Claude in the UK?
Claude is free with limited access. Claude Pro costs around £18 per month and gives access to Claude Sonnet 4 and Opus 4.1 with higher limits. Claude for Teams costs around £25 per user per month.
How much is Copilot in the UK?
Microsoft 365 Copilot costs £25.10 per user per month for business customers, on top of an existing Microsoft 365 licence. This gives access to Copilot across all Microsoft 365 apps plus the Researcher agent powered by Claude.
Verdict for pricing
If your organisation already uses Microsoft 365, Copilot adds significant value at £25.10 per user per month. If you want standalone Claude access, Pro at £18 per month is a strong value. For UK teams, combining both through the Researcher agent is the most cost effective route.
When to use Claude, when to use Copilot, and when to use both
Use Claude when…
You need deep research, long document analysis, nuanced writing or complex reasoning. You are working outside the Microsoft 365 ecosystem. You want a standalone AI assistant with a large context window.
Use Copilot when…
You are working inside Microsoft 365 apps. You need to pull from internal organisational data. You want AI integrated into your existing workflow without switching tools.
Use both when…
You want the depth of Claude for research and analysis inside the convenience of Copilot. Enable the Researcher agent in Microsoft 365 Copilot and get Claude’s capability without leaving your workflow.
Know which one you need. Not sure how to use it well?
That’s the gap the Core AI Programme closes, in three weeks.
