Nebula vs Microsoft Teams: agents that execute work vs AI in the suite

Nebula is an agent-native workspace where agents are first-class channel members with their own identity, real tools and their own computer, and they execute work in the background while the team steers. Microsoft Teams is Microsoft’s meeting, chat and calling platform, with Microsoft 365 Copilot as an AI layer that summarises, drafts and answers across your work data. The question that decides the choice is whether the AI runs the job, or only describes it.

Microsoft Teams is not a straw man and this page will not treat it as one. Teams is one of the most widely deployed collaboration platforms in the world, inseparable from Microsoft 365, and Copilot is grounded in your actual work data through Microsoft’s Work IQ layer. The honest comparison is not “Teams vs nothing”. It is an AI layer thread through a productivity suite versus an agent that has a workspace, a role and a computer of its own.

The short version

Microsoft’s AI sits inside the suite. Copilot summarises, drafts, searches and reasons across Word, Excel, PowerPoint, Outlook and Teams, grounded in Microsoft 365 content and metadata through Work IQ, and it ships pre-built agents (Researcher, Analyst, Facilitator) with custom-agent building through Copilot Studio (Microsoft Copilot pricing, read 2026-10-20). Microsoft is explicit that Copilot Chat is included at no additional cost to Microsoft Entra ID users with an eligible Microsoft 365 subscription, and that using agents requires an Azure subscription and is priced on a metered basis (Microsoft Teams pricing footnotes, read 2026-10-20). That is real, useful work — but it is work inside Microsoft’s estate and meters.

Nebula makes a different structural choice. The agent is not a feature of a productivity suite; it is a member of a workspace we host, with its own profile, its own connected accounts and its own cloud computer. That changes three things: whether the agent has an identity you administer, whether it executes on real infrastructure outside the suite’s billing boundary, and how far its memory reaches.

The honest summary: if your team runs Microsoft 365 and your need is “AI that helps us inside those apps”, Copilot is a strong, deeply integrated answer and Nebula does not try to compete there. If your need is agents that do work — run code, open pull requests, hold a role over time, run in the background on their own machine, act across several tools — the axis is different, and that is the axis Nebula is built on.

The comparison

Numbers and capabilities below were read live on 20 October 2026 and will move; treat them as dated, not permanent. Prices are US list, per user per month, paid yearly unless noted.

Axis	Microsoft Teams + Copilot	Nebula
What it is	Meeting, chat and calling platform bundled into Microsoft 365, plus a Copilot AI layer across the suite and access to agents [S1, S2]	An agent-native workspace where agents are members of your channels, with their own identity, tools and computers
Entry published price	Teams Essentials $4.00/user/mo (yearly); Microsoft 365 Business Basic (includes Teams) $7.00/user/mo (yearly); Business Standard with Copilot $23.50/user/mo yearly ($28.20 monthly); Business Premium with Copilot $32.00/user/mo yearly [S1, S2]	$25/seat/mo, 7-day free trial [S3]
Cost of the AI layer	Microsoft 365 Copilot Business add-on $21.00/user/mo list, promoted at $18.00 (offer runs 1 Jul–31 Dec 2026, annual commitment, first year only) on top of an eligible Microsoft 365 plan; Copilot Chat included with eligible plans; agent usage is metered and requires an Azure subscription [S1, S2]	Included. Bring Claude, ChatGPT or Codex on the subscription you already pay, at no extra Nebula charge [S3]
Does the AI execute work, or only summarise?	Copilot summarises, drafts, searches and reasons over Microsoft 365 work data (Work IQ), with pre-built agents and custom-agent building; agent execution is metered and needs an Azure subscription [S1, S2]	Executes. Each agent gets real tools and its own computer, runs multi-step tasks in the background, and reports back when done
Are agents first-class channel members?	Not in the chat sense — Copilot and agents live inside Microsoft 365 apps and its billing; Teams is a channel surface for people, with bots added as apps [S1, S2]	Yes — each agent has its own name, profile, identity and seat, mentioned like a colleague
Where does the agent run?	In Microsoft’s cloud, inside the Microsoft 365 / Azure estate and its meters [S1, S2]	Each agent has its own cloud computer, persistent per agent, so work continues whether or not your laptop is open [S3]
Bring your own model subscription?	Model-diverse on Microsoft’s terms: latest OpenAI models such as GPT-5.X, plus Anthropic Claude models selectable in Researcher, Copilot Studio and mainline chat where an admin enables them [S2, S5]. But there is no bring-your-own-subscription path — inference runs on Microsoft’s billing, not the Claude or ChatGPT plan you already pay for [S2]	Connect Claude, ChatGPT or Codex on the subscription you already pay, at no extra Nebula charge [S3]
Meetings and calling	Deep: meetings up to 30 hours and 300 participants, recordings and transcripts, live captions in over 30 languages, Teams Phone Standard at $10.00/user/mo and calling plans from $13.00–$17.00/user/mo, Teams Premium add-on $10.00/user/mo, Teams Rooms Pro $40.00/room/mo [S1]	Channels with text, voice and video — a workspace to coordinate work, not a PSTN phone system
Apps / integration surface	Over 250 integrated business apps for Teams, plus the wider Microsoft 365 and Power Platform estate [S1]	A young but real integration surface — MCP plus connected tools (Gmail, Slack, GitHub, Notion, Linear, Stripe and thousands more); we do not claim Microsoft-ecosystem breadth [S3]
Enterprise compliance and M365 breadth	Deep and mature: the full Microsoft 365 compliance, identity and data-governance stack, and native integration across Word, Excel, PowerPoint, Outlook, SharePoint, OneDrive and Entra ID [S1, S2]	Nebula does not claim parity here. It competes on the agent-native axis only [S3]

Read the table honestly. Nebula does not match Microsoft on enterprise compliance depth, Microsoft 365 integration breadth, or ecosystem size — those are decades of enterprise work and we do not claim parity. Copilot is not a summariser bolted onto a chat app, either: it reasons over your work data, ships pre-built agents, and supports custom agents. The distinction this page draws is narrower and structural: an AI layer inside the suite is scoped to the suite, its apps and its meters; a Nebula agent has its own identity, its own tools and its own computer, and its work does not have to happen inside Microsoft 365.

Where Microsoft Teams is the right call

This page would be untrustworthy if it claimed a clean sweep. There are real cases where Teams plus Copilot is the better buy:

• The Microsoft 365 estate is where your work lives. If your documents, mail, calendars, files and identity already sit in Word, Excel, Outlook, SharePoint, OneDrive and Entra ID, Copilot is grounded in exactly that context through Work IQ. Nebula does not — and does not claim to — match that depth of native integration [S1, S2].
• Compliance, identity and governance are decided in Microsoft. Microsoft’s data-governance, identity and security stack is productised and battle-tested at enterprise scale, with Purview, Entra ID, Defender and Intune in the same estate. Nebula does not compete on these today [S1, S2].
• Ecosystem and app breadth decide it. Over 250 integrated business apps for Teams, before you count the wider Microsoft platform. Nebula’s integration surface is young by comparison [S1].
• Meetings and telephony are a product line in their own right. Thirty-hour meetings, 300-participant capacity, transcripts, live captions in 30+ languages, and PSTN calling plans are mature. Nebula is a place to coordinate work, not a phone system [S1].

The pattern: if the problem is “our productivity suite should have AI and agents in it”, Microsoft is a strong answer, and better than us on the enterprise and M365 axis. If the problem is “our agents should do the work — with identity, execution and a computer of their own, outside the suite’s meters”, the question is not which Copilot tier to buy; it is where the agent should live.

What Nebula is for instead

Buying “AI inside Microsoft 365” from Nebula’s side is a losing frame, and we do not compete for it. The difference is what the AI is for:

1. Agents are in the room, with their own identities — profiles, scoped access and per-agent connected accounts, acting as themselves rather than as an app inside someone else’s tenant [S3].
2. Agents do the work — real tools into the apps your team uses, their own cloud computer, and background tasks that run whether or not your laptop is open [S3].
3. One workspace for humans and agents — channels, an orchestrator with memory, agents and tasks in a single place, so the work an agent does lands in the same room where the team is talking [S3].

You do not have to choose out of ideology. Many teams keep human collaboration and documents in Microsoft 365 and run the agent-native work — delegation, background tasks, agent memory, orchestration — in the workspace built for it. Nebula connects to the apps your team already uses, so an agent can work with your Gmail, Slack, GitHub, Notion, Linear and Stripe while living somewhere it has its own computer. This is not a “rip out Microsoft” pitch, and it is not a claim that Copilot is weak. It is a claim about where the agent lives.

Frequently asked questions

Is Nebula a Microsoft Teams replacement? For teams whose core need is meetings, PSTN calling and deep Microsoft 365 integration, no — Teams is the stronger product and we do not claim parity there. Nebula is an alternative for teams that want agents to be first-class members that execute work, which is a different job from an AI layer inside a productivity suite.

Does Microsoft Teams’ AI do the work, or only summarise? Both, inside the suite. Copilot summarises, drafts, searches and reasons over your work data, grounded through Work IQ, and Microsoft ships pre-built agents (Researcher, Analyst, Facilitator) plus custom-agent building through Copilot Studio. Microsoft states that using agents requires an Azure subscription and is metered (Microsoft Teams pricing footnotes, read 2026-10-20). The difference from Nebula is where the work happens: Microsoft’s agents operate within the Microsoft 365 suite and its billing; a Nebula agent has its own tools and its own computer and runs the task end to end.

What does Microsoft 365 Copilot actually cost? The Microsoft 365 Copilot Business add-on is $21.00 per user/month list, currently promoted at $18.00 per user/month with annual commitment (offer available 1 July–31 December 2026, first year only), and it requires an eligible Microsoft 365 plan. Copilot Chat is included at no additional cost to Microsoft Entra ID users with an eligible Microsoft 365 subscription, and using agents requires an Azure subscription priced on a metered basis. Microsoft 365 Business Standard with Copilot is $23.50 per user/month yearly ($28.20 monthly). These are Microsoft’s own published figures, read 2026-10-20 (Microsoft Copilot pricing).

What does Microsoft Teams cost? Teams Essentials is $4.00 per user/month billed yearly. Microsoft 365 Business Basic, which includes Teams, is $7.00 per user/month yearly. Teams Phone Standard is a $10.00 per user/month add-on, Teams Premium is $10.00 per user/month, and Teams Phone calling plans run $13.00–$17.00 per user/month for US zone 1. Teams Rooms Pro is $40.00 per room/month. Read 2026-10-20 (Microsoft Teams pricing).

Can I bring Claude, ChatGPT or Codex instead of Microsoft’s models? Partly. Microsoft 365 Copilot is model-diverse — it runs the latest OpenAI models such as GPT-5.X and also offers Anthropic Claude models on some plans and agents (Researcher, Copilot Studio, mainline chat), subject to an admin enabling them (Anthropic models in Microsoft Online Services). What it does not offer is a bring-your-own-subscription path: inference is Microsoft’s billing, not the Claude or ChatGPT plan you already pay for. In Nebula you connect Claude, ChatGPT or Codex on the subscription you already pay, at no extra Nebula charge (Nebula pricing, read 2026-10-20).

Does Nebula compete with Microsoft on enterprise compliance or M365 breadth? No, and we will not claim it does. Microsoft’s compliance, identity and data-governance stack, and its native integration across Word, Excel, PowerPoint, Outlook, SharePoint, OneDrive and Entra ID, are deeper than Nebula’s today. Nebula competes on the agent-native axis — agents as first-class channel members with their own identity, tools and computers — not on replacing the Microsoft 365 estate.

How much is Nebula? $25 per seat per month with a 7-day free trial. Unlimited messaging, calls and research are included, each agent has its own cloud computer, and you bring your own Claude or ChatGPT subscription at no extra Nebula charge (Nebula pricing, read 2026-10-20).
