Quick Summary
- Microsoft’s AI offering inside M365 stacks in three layers, each building on the one below.
- Layer 1 — Copilot Free: reasoning and web access, free with any M365 tenant, but blind to your business data.
- Layer 2 — M365 Copilot: adds a connector to your mail, calendar, SharePoint and Teams, plus Researcher, Agents, scheduled prompts and Copilot Studio.
- Layer 3 — Copilot Cowork: the newest layer. Takes autonomous, multi-step action across your systems rather than just producing text.
- Most teams already on Copilot are using a fraction of what they pay for.
- If you don’t have Copilot yet, the value case is no longer just about inline drafting — it’s about Researcher, Agents and Cowork workflows.
Copilot Free, M365 Copilot, GitHub Copilot, Copilot Studio, and now Cowork. They all share a name, which makes it hard to know what you have, what to expect from it, and what’s worth paying for.
Here is the simplest way to think about it. There are three layers, and each one builds on the one beneath.
Layer 1 — Copilot Free
Free with any Microsoft 365 tenant.
The bottom layer is the free Copilot anyone with a Microsoft account can use. Under the hood it is a secured version of ChatGPT with web access, in Microsoft’s UI.
- What it does: drafts, summarises, brainstorms, translates, writes code, and answers general questions.
- What it cannot do: see anything inside your organisation. No inbox, no SharePoint, no Teams meetings, no OneDrive.
- Best thought of as: a smart generalist who has read the internet but has never set foot in your office.
Layer 2 — M365 Copilot
From around $35 per user per month for SMB on a monthly contract.*
The paid tier keeps everything from Layer 1 and adds the thing that matters in a business context: a secure connector to your tenant’s data, bounded by your existing permissions.
Suddenly prompts like “what is the latest version of the Acme proposal?” or “summarise the three exec meetings I had last week” actually resolve against real data instead of guesses.
Four features in this layer are worth calling out:
Researcher: a reasoning agent for multi-step research. Plans the work, pulls from your tenant and the web, and produces a structured report. The kind of task that used to take a junior analyst half a day.
Scheduled prompts: rolling out through Agent Builder in mid-2026. Set a prompt to run hourly, daily, weekly or monthly – a Monday competitor scan, a weekly project digest, a quarterly feedback summary.
Agents: small, purpose-built assistants you can spin up without a developer. Point one at your HR policy library and anyone can ask “how much parental leave am I entitled to?” and get a grounded, citable answer.
Copilot Studio: A low-code environment for building more sophisticated agents with custom workflows, multiple knowledge sources & external connections. Power-user rather than every-end-user territory.
This layer is the workhorse for most knowledge workers. It is where AI stops being a novelty and starts becoming part of the workflow
Layer 3 — Copilot Cowork
The newest layer in the stack.
The top of the stack is where things shift from generating outputs to taking actions.
Cowork is an agent that operates inside your M365 environment, aimed at non-developers. It runs multi-step workflows across your files and tasks, drafts and sends email, and operates on a schedule.
The distinction from Layer 2 is subtle but important. Layer 2 tells you what to do. Layer 3 does it.
A few real-world workflows people are already running:
- Week-ahead briefing: reviews your calendar, identifies leads and projects hidden in the invites, researches each company and attendee, and lands a background pack in your inbox.
- Site weather monitoring: pulls project addresses from Dynamics, runs weather checks against each, and flags sites likely to be hit by adverse conditions.
- New lead enrichment: when a contact lands in Dynamics, researches the company, checks for existing relationships across mailboxes, and drafts a tailored first-touch email.
- Pipeline hygiene: a weekly sweep through CRM. Stale deals surfaced, draft follow-ups grounded in the last real interaction, queued for Monday morning review.
- Overnight inbox triage: drafts replies to routine items into your Drafts folder, flags the genuinely urgent ones at the top of a digest, and files the FYI noise out of the way.
Where Most Businesses Sit Today
From what we are seeing across our customers:
- If you are on Layer 1 only: you are leaving the highest-value work on the table. Almost every useful workplace prompt needs your business data to answer well.
- If you have M365 Copilot: there is a strong chance you are using it for inline drafting in Word, Outlook and Teams and little else. Researcher, Agents and scheduled prompts are usually the quickest wins.
- If you are ready for Layer 3: Cowork is where the conversation moves from “generate this for me” to “do this for me, on a schedule, across my systems.”
