Verdict: If your team already lives in Microsoft 365, Microsoft 365 Copilot Business is the natural productivity layer. If your team uses Gmail, Google Docs, and Google Meet, Google Workspace Business Standard or Plus now bundles Gemini AI at a modest price increase and is the best value. If your work is mostly research, writing, coding, or creative tasks outside of Office or Workspace, ChatGPT Business is the better standalone AI assistant.

What we are comparing
This article compares the three leading AI-powered productivity suites for small businesses in 2026:

- ChatGPT Business (formerly ChatGPT Team) — OpenAI’s team workspace for chat, reasoning, coding, and content creation.

Microsoft 365 Copilot Business
Microsoft 365 Copilot Business is an add-on that sits on top of a qualifying Microsoft 365 Business plan such as Business Standard or Business Premium.
- Price: $18/user/month promotional (standard $21) with annual commitment through September 30, 2026.
- Requires: A separate Microsoft 365 Business Standard, Business Premium, or eligible enterprise license.
- What it does: Drafts and edits in Word, summarizes long email threads and suggests replies in Outlook, analyzes data and writes formulas in Excel, builds slide decks in PowerPoint from briefs, and summarizes Teams meetings and chats.
- Copilot Chat: Included at no extra cost for eligible Microsoft 365 subscribers. It gives secure, web-grounded AI chat, but it is not grounded in your work data unless you upgrade to Copilot Business.
- Agents: You can build agents in Copilot Studio (additional metered cost).
Best for: Businesses already paying for Microsoft 365 who want AI inside the apps they already use every day.
ChatGPT Business
ChatGPT Business (formerly ChatGPT Team) is OpenAI’s team plan. It is a standalone AI workspace, not tied to Office or Google apps.
- Price: $20/user/month when billed annually; $25/user/month when billed monthly. Minimum 2 seats.
- What it does: Unlimited access to GPT-5.x models, deep research, Codex coding agent, canvas for documents and code, image generation, custom GPTs, and 60+ app connectors.
- Privacy: Conversations are not used to train OpenAI models by default.
- Admin controls: Shared workspaces, admin console, SAML SSO, MFA, domain verification, bulk member management, and usage analytics.
- Limits: It does not natively edit your live Word documents, Excel files, or Google Sheets. You copy/paste or upload files.
Best for: Teams that want the most capable general-purpose AI assistant for writing, coding, research, and analysis, and do not need deep integration into Office or Workspace apps.
Google Workspace AI
Google dropped the standalone Gemini add-on in 2025. Today, Google Workspace Business plans include Gemini directly.
- Business Starter: roughly $7–$8/user/mo with limited Gemini in Gmail and the Gemini app.
- Business Standard: roughly $14/user/mo with Gemini in Gmail, Docs, Sheets, Slides, Drive, Meet, and Chat.
- Business Plus: roughly $22/user/mo with enhanced security, 500-participant meetings, 5 TB storage, and full Gemini.
- What it does: “Help me write” in Gmail and Docs, generate slides and images in Slides, build spreadsheets and formulas in Sheets, summarize Meet meetings, create AI videos in Vids, and answer questions across Drive files via the Gemini app.
Best for: Businesses already using Gmail, Google Docs, and Google Meet that want AI baked in at a lower per-seat cost than Microsoft Copilot.
How to decide
| Scenario | Recommended choice | Why |
|---|---|---|
| You run everything in Outlook, Word, Excel, and Teams | Microsoft 365 Copilot Business | Native integration is unmatched; you do not leave your apps. |
| You use Gmail, Docs, Sheets, and Meet | Google Workspace Business Standard/Plus | AI is bundled; cheaper than M365 + Copilot add-on. |
| You need an AI assistant for research, writing, code, or analysis | ChatGPT Business | Best general-purpose models and reasoning tools. |
| You are cost-sensitive and only need basic AI | Google Workspace Business Starter | Cheapest entry with some Gemini access. |
| You need custom AI agents across business systems | Microsoft Copilot Business + Copilot Studio | Strongest enterprise agent platform. |
| You handle sensitive data and need audit/compliance controls | ChatGPT Enterprise or Microsoft Copilot Enterprise | Both offer SSO, SCIM, audit logs, and data residency. |
Real cost example: 5-person team
| Stack | Estimated monthly cost | Notes |
|---|---|---|
| Microsoft 365 Business Standard + Copilot Business (promo) | ~$164/month | ~$14.80 base + $18 Copilot × 5 |
| Google Workspace Business Standard (Gemini included) | ~$70/month | ~$14 × 5 |
| ChatGPT Business (annual) | $100/month | $20 × 5 |
If budget is tight and you already use Google apps, Workspace is the clear winner. If you are already in Microsoft, the productivity gain may justify the higher price.
FAQ
Q1: Can I use ChatGPT Business instead of Copilot if my company uses Microsoft 365? Yes. Many teams do. But you lose the convenience of AI inside Word, Outlook, Excel, and Teams. You will copy/paste between apps.
Q2: Does Google Workspace AI replace ChatGPT or Copilot? Not entirely. Gemini in Workspace is excellent for email, documents, meetings, and search. For deep research, coding, or advanced reasoning, ChatGPT Business or Copilot Business may still be stronger.
Q3: Will my company data be used to train AI models? No — or at least not by default. Microsoft, OpenAI (Business/Enterprise), and Google all state that business customer data is not used to train their AI models. Always check your data processing agreement for your region.
Q4: Is there a free trial for these team plans? Google Workspace offers a 14-day trial. Microsoft 365 Copilot Business does not offer a trial, but Copilot Chat is free with eligible M365 plans. ChatGPT Business has no free trial and requires at least 2 seats.
Q5: Which has the best AI meeting assistant?
- Microsoft Copilot Business: summarizes Teams meetings and action items natively.
- Google Workspace: Gemini in Meet takes notes and summarizes.
- ChatGPT Business: no native meeting integration; you upload transcripts manually.
