Claude Team vs ChatGPT Business vs Microsoft 365 Copilot

Claude Team

9.4 $20

ChatGPT Business

9.5 $20

Microsoft 365 Copilot

9.1 $30

Verdict

Claude Team

Anthropic's team plan, aimed at writing, reasoning, and long-document work, with shared Projects and up to a 1M-token context; premium seats add Claude Code for engineers. Worth weighing: opaque usage limits, $100+ premium seats, no EU data residency, and no image generation.

ChatGPT Business

The most flexible single AI subscription: GPT-5.5 plus Deep Research, Custom GPTs, Canvas, and the Codex coding agent in one team workspace with strong admin controls. The two-seat minimum and per-seat feature limits aside, it does the most for the money.

Microsoft 365 Copi

The default AI layer for Microsoft-heavy teams: unmatched inside Word, Excel, Outlook, and Teams, and grounded in your own data through Graph. Just budget for the base license it rides on (real cost runs 2-3x the add-on price), and don't expect it to reach non-Microsoft tools.

Best for

Claude Team

People and teams that need thoughtful writing, long-document work, study help, reflection, research synthesis, strategy docs, and careful editing.

ChatGPT Business

Small businesses, solo operators, students, creators, and teams that want one flexible AI assistant for writing, research, planning, analysis, brainstorming, and everyday productivity.

Microsoft 365 Copi

Teams already standardized on Microsoft 365 who want AI built directly into the apps they live in — drafting and triaging email in Outlook, recapping meetings and surfacing action items in Teams, generating and rewriting documents in Word, building slides in PowerPoint, and getting formula and analysis help in Excel — without copying work into a separate chatbot.

Avoid if

Claude Team

your highest priority is design assets, native Microsoft or Google integration, or a lower-cost grammar-only tool.

ChatGPT Business

your main need is AI embedded directly inside Microsoft 365 or Google Workspace, or you only need a narrow specialist tool for design, grammar, or source-backed research.

Microsoft 365 Copi

Your organization isn't on a qualifying Microsoft 365 business plan, your team mostly works in Google Workspace or standalone tools, or you primarily want a general-purpose chat assistant for research and writing rather than AI embedded inside the Office apps.
