Plug and AI vs Microsoft 365 CopilotMicrosoft 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 runs on the models Microsoft picks — OpenAI and Anthropic (Claude), selectable in Copilot Chat since 2026. Plug and AI puts GPT, Claude, Gemini, Grok and 300+ models inside Microsoft Teams — pay only for what your team uses.
Free starter credit for new tenants · No per-seat fees · No annual commitment
Plug and AI is a multi-model AI app for Microsoft Teams. It routes your prompts to providers like OpenAI, Anthropic, Google and xAI — so you get the best model from every provider, right inside the Teams client your organization already uses.
Microsoft 365 Copilot is a capable, deeply integrated product — but it bills a fixed per-seat fee and keeps you on Microsoft's chosen models. Here's why teams add Plug and AI to Teams instead (or alongside).
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), on top of a qualifying Microsoft 365 subscription. For a team of 10, that's $210–300/month on yearly billing (more if paid monthly) — whether every seat is heavily used or barely touched.
Plug and AI: $0 fixed cost, no per-seat fee, no annual commitment. Pay only for what your team actually sends. Costs scale with usage rather than headcount.
Copilot runs on the models Microsoft selects and hosts — OpenAI and Anthropic (Claude) — and you choose only among the models Microsoft offers. But sometimes Claude is better for long-document analysis, Gemini for search-grounded answers, or DeepSeek for coding. No single model is best at everything.
Plug and AI: Access 300+ models from OpenAI, Anthropic, Google, xAI, DeepSeek, Meta, Mistral and more — all from one Teams app. Pick the right model per task, right in the message:
Microsoft 365 Copilot is an add-on — it requires a qualifying Microsoft 365 business or enterprise plan underneath it (as of 2026). The free "Microsoft Copilot" chat tier exists, but it doesn't include the Office-document authoring or Teams AI agent capabilities of the paid product.
Plug and AI: Installs straight into Teams from the Microsoft marketplace — no Copilot add-on, no per-seat license. Every new tenant starts with free credit.
With Copilot, every user needs their own licensed seat, usually on a yearly subscription (monthly billing costs more). That means seat management, license true-ups, and paying for people who barely use it.
Plug and AI: One shared balance covers your whole Microsoft 365 tenant. Top up once via Stripe. No per-user accounts, no seat counting, no annual lock-in.

Copilot pricing and packaging as reported publicly as of 2026; verify current terms on Microsoft's pricing page.
10 seats × $30/user/month at the enterprise Microsoft 365 Copilot price, paid yearly (as of October 2026) — plus your existing Microsoft 365 subscription. The Copilot Business tier (up to 300 users) is $21/user/month paid yearly — about $210/month; Microsoft runs an $18 first-year promo through Dec 31, 2026.
One shared tenant balance for the same 10 people — pay per use at usage-based rates (details on the pricing page), no seats.
Actual Plug and AI cost depends on usage and which models you pick; free open-source models cost $0. See an illustrative calculation on the pricing page.
We'll be straight with you: Copilot has a genuine advantage Plug and AI does not try to match. Choose Microsoft 365 Copilot if:
You need AI writing inside Word, Excel, PowerPoint and Outlook. Copilot generates and edits content directly in your Office documents and mailbox. Plug and AI is a Teams chat assistant — it does not author inside Office files.
You want everything under one Microsoft agreement with Microsoft's own data-residency and compliance commitments across the whole M365 stack.
You rely on Microsoft Graph grounding across SharePoint, OneDrive and your org's documents inside the Office apps.
For flexible, multi-model AI chat in Teams without per-seat cost — model choice per message, image generation, vision, and file analysis on one shared tenant balance — Plug and AI is the better fit. Many teams run both: Copilot for Office authoring, Plug and AI for everyday multi-model chat.
Open Plug and AI on the Microsoft marketplace or click "Add to Microsoft Teams". Installs in under a minute.
Message the bot 1:1 or @mention it in a channel. New tenants get free starter credit — no card required to begin.
Set a per-tenant default chain, or switch models per message. Top up the shared balance via Stripe whenever you need to.
Plug and AI is a pay-per-use alternative that runs inside Microsoft Teams. 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 requires a qualifying Microsoft 365 subscription. Plug and AI has no per-seat fee — you share one balance per Microsoft 365 tenant and pay only for what your team actually uses (usage-based rates; details on the pricing page; free models cost $0), versus $210–300/month for 10 Copilot seats.
Yes. Plug and AI brings GPT (OpenAI), Claude (Anthropic), Gemini (Google), Grok (xAI), DeepSeek and 300+ more models directly into Microsoft Teams. You pick the model per message and can switch mid-conversation. Microsoft 365 Copilot uses the models Microsoft selects and hosts — OpenAI and Anthropic (Claude), selectable in Copilot Chat since 2026 — so you don't get per-message choice across 300+ models from many labs the way you do with Plug and AI.
