There's no official OpenAI chatbot you can talk to inside the Teams client. The practical way to get GPT — plus Claude, Gemini and 300+ models — right in Teams is Plug and AI. Pay per use, no per-seat fees.

Short answer: not the kind you're probably looking for. As of 2026, OpenAI does not publish a ChatGPT chatbot that you install into the Microsoft Teams client and chat with directly.
OpenAI does offer an official Microsoft Teams connector — but it's primarily the other way around. It lets ChatGPT (on ChatGPT's own website and apps) securely search and read your Teams chats and channels for context. It requires a paid ChatGPT Business, Enterprise or Edu plan and needs your Microsoft Entra admin to approve its scopes. As of 2026 its actions can include sending messages, but that's admin-gated and still driven from ChatGPT's side — it is not a chatbot living inside the Teams client.
So if your goal is to type a prompt in Teams and get a GPT answer back in Teams, you need a third-party AI app. Plug and AI is one — live in the Microsoft Teams marketplace, giving you GPT models plus Claude, Gemini, Grok and DeepSeek without a per-seat subscription.
All three are legitimate — they just solve different problems. Here's an honest survey so you can pick.
Lets ChatGPT.com search and read your Teams messages for context. Good if you already pay for ChatGPT Business/Enterprise and want ChatGPT to reference your Teams conversations. But it lives on ChatGPT's side, not inside Teams — it isn't a chatbot in the Teams client and won't answer prompts in a Teams chat (its message-sending actions, added by 2026, are admin-gated and still driven from ChatGPT). It requires a per-seat ChatGPT subscription (Business ~$25/user/month annual or ~$30 monthly as of 2026, Enterprise/Edu custom) and needs Entra admin approval.
Microsoft's own assistant, built on OpenAI models and deeply integrated across Microsoft 365 — Word, Excel, Outlook and Teams. It's the most "native" option, but it's licensed per user, and you're locked to whichever models Microsoft ships. See our Microsoft Copilot alternative comparison.
A standalone Teams app you install from the marketplace. Message it 1:1 or @mention it in any channel and it replies using your tenant's default model chain — GPT, Claude, Gemini, Grok, DeepSeek and 300+ more via OpenRouter. Switch the chain any time with model premium. Pay-per-use from a shared tenant balance, no per-seat fees, free starter credit.
In Microsoft Teams, click Apps in the left sidebar. Or skip straight to the direct install link.
Type Plug and AI into the app store search. It's published in the Microsoft Teams marketplace.
Add it for yourself, or add it to a team/channel so everyone can @mention it. Every new tenant gets a free starter credit, so you can try GPT immediately — no credit card required.
Just type — chat 1:1 with the bot, or @mention it in a channel, and it answers with your tenant's current model chain:
To change which models answer, send model premium (or another alias like balanced) — that sets the default model chain for the whole tenant. The premium chain includes GPT and Claude models. Send model on its own to see the current chain.
OpenAI's GPT models alongside Claude, Gemini, Grok, DeepSeek and 300+ more via OpenRouter. Set the tenant's default chain with model premium.
Message the bot privately, or @mention it in any channel to bring AI into a group conversation.
Generate images from a prompt, or send a screenshot or photo and ask the AI to analyze what it sees.
Attach a PDF or an HTML file and ask questions about it — summaries, extraction, review — right in the chat.
Set a default model chain for your whole tenant, so the team gets a sensible default without naming a model every time.
A personal tab shows your usage and balance so you always know where your shared credit stands.
Getting only GPT into Teams solves half the problem. No single model wins every task — and being locked to one provider means paying for its worst days too.
With Plug and AI you set the right default model chain for your tenant — and switch it any time with a single model command as your needs change. Want Claude specifically?

ChatGPT Business is about $25/user/month on annual billing (roughly $30 month-to-month) as of 2026; Enterprise and Edu are custom-priced — see openai.com pricing. Figures shown use the Business tier and per-seat cost scales with headcount. Prices subject to change by the respective vendors. Plug and AI charges AI provider rates plus a 10% service fee.
Not in the way most people expect. As of 2026 there is no official OpenAI chatbot you install into the Teams client and talk to. OpenAI does offer an official Microsoft Teams connector, but it's primarily the other way around — it lets ChatGPT (on its own website/app) securely search and read your Teams chats and channels for context. It requires a paid ChatGPT Business, Enterprise or Edu plan and Microsoft Entra admin approval. As of 2026 its actions can include sending messages, but that's admin-gated and still driven from ChatGPT's side — it is not a chatbot living inside the Teams client. To actually chat with GPT inside Teams you use a third-party app such as Plug and AI, Microsoft Copilot (built on OpenAI models), or a custom Azure OpenAI bot.
Open Microsoft Teams, go to Apps, search for "Plug and AI", and click Add — or use the direct install link. Every new tenant gets a free starter credit, so you can send a message to GPT immediately. Then chat 1:1 or @mention the bot in any channel. To change which models answer, send model premium (or another alias like balanced) — that sets the default model chain for the whole tenant.
OpenAI's official Teams connector requires a paid ChatGPT plan. As of 2026 ChatGPT Business runs about $25 per user per month on annual billing (roughly $30 monthly), while Enterprise and Edu are custom-priced — see openai.com pricing. On the Business tier a team of 10 is therefore roughly $250-300/month at monthly billing, less on annual, and per-seat cost keeps scaling with headcount. Plug and AI has no per-seat fee: you pay per use at AI provider rates plus a 10% service fee, from one shared tenant balance. A team of 10 with moderate usage typically spends around $35/month, and every new tenant starts with free credit.
Yes. Plug and AI gives you OpenAI's latest GPT models directly in Teams, alongside Claude, Gemini, Grok, DeepSeek and 300+ other models through OpenRouter. Send model premium (or another alias like balanced) to set the tenant's default model chain — the premium chain includes GPT and Claude models.
Plug and AI sends your prompts via API to the providers in your tenant's model chain, routed through OpenRouter. Because a chain has fallbacks, a request may be served by another model or provider in the chain if the primary one fails. It all runs on standard API terms — leading providers do not train their models on data sent through their standard API — and billing is per API call from a shared tenant balance, with no per-seat accounts needed. We don't claim specific compliance certifications here — evaluate the app against your own organization's security and data-handling requirements before rolling it out.
Microsoft Copilot is Microsoft's own assistant, built on OpenAI models and deeply woven into Microsoft 365 (Word, Excel, Outlook, Teams). It's licensed per user and locks you to Microsoft's chosen models. Plug and AI is a standalone Teams app that gives you many providers' models — GPT, Claude, Gemini, Grok, DeepSeek and more — with pay-per-use pricing and no per-seat license.
