Copilot Chat vs Microsoft 365 Copilot is one of the first questions an owner or IT lead asks once Copilot appears in Teams and Outlook. One comes with the plan you already pay for. The other is a paid add-on for each person who gets it. Choosing well matters, because a seat that nobody uses is money spent for nothing.
This post explains what each option includes today, the names Microsoft now uses and a practical way to decide who should get a paid licence.
First, the new names
Microsoft has renamed both. The Microsoft 365 Copilot Chat app is now called Microsoft Copilot Chat, and the Microsoft 365 Copilot app is now Microsoft Copilot. You will still see the old names in contracts, older articles and search results, so this post uses both where it helps. On Microsoft's Copilot overview, the experiences are labelled Copilot Chat (Basic), Microsoft 365 Copilot (Basic) and Microsoft 365 Copilot (Premium).
What does Copilot Chat include?
Copilot Chat is the baseline included with eligible Microsoft 365 plans. People sign in with their work account and get a secure AI chat at copilot.cloud.microsoft, in the Microsoft Copilot app, in Edge, and inside Outlook and Teams. When they sign in with their Microsoft Entra account, prompts and responses are covered by Microsoft's enterprise data protection.
Its answers come mainly from the public web. It can work with your organisation's content, but only when someone brings it in: by pasting it into the prompt, uploading a file, or using Copilot Chat in Outlook or Teams alongside content they have open. It does not search a person's mailbox, files and meetings through Microsoft Graph on its own.
Agents follow the same pattern. Agents built from instructions and public websites are included. Agents that draw on work data are available on a pay-as-you-go basis, which an admin sets up in the Microsoft 365 admin centre by linking a billing policy to an Azure subscription.
What does a Microsoft 365 Copilot licence add?
The paid licence, labelled Microsoft 365 Copilot (Premium), is an add-on for each user on top of an eligible plan. The big difference is grounding. Copilot uses web data and work data automatically, through Microsoft Graph and Work IQ: the emails, files, meetings, calendars and teams each person already has permission to see. Nobody has to upload anything first.
It also brings priority access to the full Copilot experience in Word, Excel, PowerPoint and OneNote, agents that use both web and work data, and more advanced admin controls and analytics. SharePoint Advanced Management comes with it too, which matters if you want Microsoft's tools for reducing oversharing and clearing out inactive sites.
Between the two sits Microsoft 365 Copilot (Basic). Some people without the add-on still get standard access to Copilot inside Word, Excel, PowerPoint and OneNote. Standard access depends on service capacity and can vary through the day. Exactly which experience your people see depends on your plan and tenant settings.

For organisations with up to 300 users on Microsoft 365 Business plans, Microsoft also sells Microsoft Copilot Business, an add-on with the same Copilot capabilities, on an annual commitment. Larger organisations use the enterprise options. Microsoft's Copilot licence options list the plans each one can be added to, including Business Basic, Business Standard and Business Premium.
Who needs a Microsoft 365 Copilot licence?
There is no single right answer, but the pattern is usually clear once you look at how people work. A paid seat makes most sense for someone whose day runs through email, meetings and documents in Microsoft 365, where having Copilot pull those together saves real time. Copilot Chat is often enough for people who use AI now and then, or whose work happens mostly outside Microsoft 365.
Strong candidates for a paid seat
- Managers and coordinators who spend much of the day in Outlook and Teams and need to catch up quickly.
- People who write, review or summarise long documents and want Copilot to find related files without being told where they are.
- Finance staff and analysts who would use Copilot inside Excel every day.
Usually fine with Copilot Chat
- Occasional users who draft an email or summarise a web page from time to time.
- Frontline and field staff whose work happens away from email and documents.
- Anyone happy to upload the one file they need, rather than have Copilot search for it.
A sensible way to decide
- Give everyone Copilot Chat first. It is included with eligible plans and shows you who reaches for AI at all.
- Check permissions before any paid seat goes live. With a paid seat, Copilot can draw on anything that person can open, so review SharePoint access first. Our oversharing check before Copilot shows where to start.
- Pilot with a named group. Choose people from the candidate list above, agree what success looks like and give them some training.
- Measure real use. Microsoft's Copilot Chat usage report covers chat across every licence type, and the Microsoft Copilot usage report shows use inside apps such as Teams, Outlook, Word and Excel.
- Move seats to where they are used. Before each renewal, find the licences nobody opens and reassign them to people who have asked.
If pay-as-you-go agents are part of the plan, add a budget to the billing policy. Microsoft lets admins set a budget limit with email alerts as spending reaches set points, as its pay-as-you-go overview explains.
Keeping licences honest after rollout
UsagePoint, our SharePoint app on Microsoft Marketplace, is built for that renewal decision. It shows which Microsoft 365 Copilot seats are in use, prices idle seats in pounds at the price you actually pay, and lets you nudge, reclaim or reassign seats, with every action waiting for approval. Usage data stays in your tenant, and it never reads prompts or answers. You can trial it in full for 14 days from install, with no licence key needed.
For the people side, our Copilot adoption and licence value service starts from your usage data, adds practical training and gives a straight view on where licences pay back and where you can automate without them. Like our other consultancy work, it is priced after a free call, with a written fixed quote before work starts.
