Google Workspace with Gemini

Verdict

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.

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.

Google Workspace w

The natural AI layer for Google-native teams: Gemini is baked into Gmail, Docs, Sheets, and Meet at $14/user/mo on Business Standard, with no add-on to manage. The catch is it's all-or-nothing per plan (everyone pays for AI), and the deepest features need Enterprise.

Best for

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.

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.

Google Workspace w

Teams already running on Google Workspace who want AI inside the tools they use daily — drafting and summarizing email in Gmail, writing and refining in Docs, organizing and analyzing data in Sheets, building decks in Slides, and getting note-taking and recaps in Meet — with low-friction rollout and minimal change to existing habits.

Avoid if

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.

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.

Google Workspace w

Your team runs primarily on Microsoft Office or other non-Google tools, you need the deepest possible reasoning on long technical documents, or you want a standalone research assistant rather than AI woven into Gmail, Docs, Sheets, Slides, and Meet.
