Best AI Apps for Microsoft Teams 2026Ranked & Compared
We compared the top AI apps for Microsoft Teams — chat assistants, Office integration, and meeting note takers — on models, pricing, and features. Here's our ranking.
Microsoft Teams AI apps fall into three broad categories: chat & content assistants (ask questions, draft, analyse), Office/Graph integration (act on your documents and org data), and meeting note takers (transcribe and summarise calls). We rate each app for what it is best at rather than forcing one score across categories. Facts about third-party apps below were verified against public sources as of October 2026; where pricing or availability may change, we say so.
Full disclosure: Plug and AI is our own product. We rank it #1 in the multi-model chat-assistant category because that is where it is genuinely strongest — but we list honest cons for it, and it is not the right pick for Office-document work or meeting transcription. Read the trade-offs and choose what fits your team.
Plug and AI is a multi-model chat assistant for Microsoft Teams. Instead of locking you into one provider, it routes prompts to GPT, Claude, Gemini, Grok, DeepSeek, and 300+ more models through OpenRouter — and you only pay for what you use, from one shared tenant balance. It works in 1:1 chat and via channel @mentions, and adds image generation, vision, and PDF/HTML analysis. There's no fixed monthly fee or per-seat fee, with a free starter credit to begin.

Office/Graph integration · Native to the Teams client
Microsoft 365 Copilot is the only assistant on this list that lives inside the Teams client itself. It uses Teams' own live transcription to generate meeting summaries and action items, and it reaches across Word, Excel, PowerPoint, Outlook, and SharePoint grounded in your organisation's data via Microsoft Graph. That deep Office integration is its superpower — and its price. See the Copilot alternative comparison →

Deep Word/Excel/PowerPoint/Outlook integration
Grounded in org data via Microsoft Graph

Pricing:$21/user/mo Business or $30/user/mo enterprise, paid yearly (add-on to a qualifying M365 plan); free Copilot Chat tier
AI research & agent tasks · @Computer mentions and DMs
Perplexity brought its "Computer" agent to Microsoft Teams and listed it in the Microsoft Marketplace. You tag @Computer in a shared channel or DM it directly, describing a task in plain language. It connects to Microsoft tools like Outlook, OneDrive, SharePoint, Excel, and Azure DevOps to bring context into the work — strongest for web-grounded research and multi-step agent tasks.
Pros
Web-grounded research with citations
Agent tasks via @Computer mentions and DMs
Connects to Outlook, OneDrive, SharePoint, Excel, Azure DevOps
Cross-platform with perplexity.ai
Cons
Requires Perplexity Pro, Enterprise Pro, or Max

Otter.ai is one of the most widely recognised AI note takers, with long market history.

Meeting-notes only — not a general chat assistant
Joins as a visible bot participant

Fireflies.ai automatically joins Teams meetings and captures dialogue with high transcription accuracy across 60+ languages.

Pros
High transcription accuracy, 60+ languages
CRM sync (Salesforce, HubSpot, Pipedrive)
Conversation intelligence and search
Cons

How to Choose the Right Teams AI App
You want a flexible chat & content assistant
Pick Plug and AI if you want to ask questions, draft content, generate images, and analyse files across many models — GPT, Claude, Gemini, and more — without per-seat fees. See ChatGPT for Microsoft Teams and Claude in Microsoft Teams.
You live in Word, Excel, and Outlook
Pick Microsoft 365 Copilot if you need AI that acts directly on your Office documents and org data — and you can budget the per-seat add-on. Weighing it up? Read our Microsoft Copilot alternative comparison.
You mainly need meeting notes
Pick a note taker — Otter, Fireflies, Read AI, or Fellow. These transcribe and summarise calls; they are not general chat assistants, so many teams pair one with Plug and AI.
You want web research with citations
Pick Perplexity if research and agent tasks are your core need and you already have a Perplexity subscription.
Our Verdict
BEST FOR MULTI-MODEL CHAT
Plug and AI — Best Multi-Model AI App for Microsoft Teams in 2026
No other Teams app gives you this combination: 300+ models from every major provider, pay-per-use pricing with no per-seat fees, and a shared tenant balance you can start with free credit. Need GPT for writing, Claude for reasoning, or Gemini for analysis? Pick the right model per question — all from one app.
Being honest about scope: if your priority is Office-document automation, Microsoft 365 Copilot is the native pick; if it is meeting transcription, Otter, Fireflies, Read AI, or Fellow lead. Many teams run Plug and AI for everyday AI chat alongside a note taker — and skip Copilot's per-seat bill.
What is the best AI app for Microsoft Teams in 2026?
It depends on the job. For a flexible chat assistant, Plug and AI is the most flexible pick: it brings 300+ AI models — including GPT, Claude, Gemini, Grok, and DeepSeek — into Teams with pay-per-use pricing and no per-seat fees. For deep Office-document integration, Microsoft 365 Copilot is the native choice. For meeting notes, Otter, Fireflies, Read AI, and Fellow lead. Disclosure: Plug and AI is our product.
Is Microsoft Copilot the only AI for Teams?
No. Microsoft 365 Copilot is the native, built-in option, but the Microsoft Teams marketplace hosts many independent AI apps. Plug and AI adds multi-model chat (GPT, Claude, Gemini and more) with pay-per-use pricing; Perplexity brings AI research; and Otter, Fireflies, Read AI, and Fellow specialise in meeting transcription. You can run these alongside — or instead of — Copilot. See our Microsoft Copilot alternative guide.
What is the cheapest AI assistant for Microsoft Teams?
For chat assistance, Plug and AI has a $0/month fixed cost, pay-per-use billing, no per-seat fees, and a free starter credit — you pay usage-based rates (details on the pricing page) for what your team actually uses, and free models cost $0. By contrast, Microsoft 365 Copilot is $21/user/month for Copilot Business (up to 300 users) or $30/user/month for enterprise, paid yearly (as of October 2026), and meeting note takers use per-seat subscriptions. Microsoft 365 Copilot Chat has a free tier for eligible Microsoft 365 subscribers, but without full Office integration.
Which Teams AI apps support GPT and Claude?
Plug and AI supports both GPT and Claude — plus Gemini, Grok, DeepSeek, and 300+ models via OpenRouter — in the same Teams app, with model switching mid-conversation. Microsoft 365 Copilot lets licensed users pick between Microsoft-selected OpenAI and Anthropic (Claude) models, but not Gemini, Grok or DeepSeek. Most meeting note takers use their own models and do not expose model choice.
Which AI note taker is best for Microsoft Teams?
For meeting transcription and summaries in Teams, the leading tools in 2026 are Otter.ai (OtterPilot), Fireflies.ai, Read AI, and Fellow. Fellow and Fireflies integrate natively through Microsoft AppSource, while Otter, Read AI, and Fireflies can also join calls as a bot participant. Plug and AI is a chat and content assistant, not a meeting transcription tool, so pair it with a note taker if you need both.
