Kylon vs Microsoft Copilot
Copilot helps you write. Kylon runs the task end to end.
Kylon is a company harness where agents join your team, understand your business context, and execute real work across the tools you already use.
01 Which one is the right answer
Not every team should pick the same one.
Copilot is the right answer when
The work is the document. Drafting in Word, analysing in Excel, clearing an Outlook thread, all on data Microsoft already holds for you.
Kylon is the right answer when
The task crosses tools that are not all Microsoft, takes several steps, and needs someone to approve the result before it is sent or saved.
02 Operating model
How each one works
Every statement about Microsoft 365 Copilot below cites Microsoft's own documentation. Checked 2026-09-09.
Where it lives
Copilot pairs with the Microsoft 365 apps: Word, Excel, PowerPoint, Outlook, Teams and Loop, helping in the context of the open document or thread.
Source: What is Microsoft Copilot?
An agent lives in a room with the team, not inside one file, and works across whichever connected tools the task needs.
What it reads
Copilot grounds the prompt with Microsoft Graph data in your tenant: the emails, chats and documents the signed-in user already has permission to access.
Source: Microsoft Copilot architecture and how it works
The room, the workspace records, and 3,000+ connected services, including the ones outside Microsoft.
One turn or a task
A prompt is grounded, sent to the model, and the response comes back to the app the user is in.
Source: Microsoft Copilot architecture and how it works
A request can run as multiple steps across tools, on a schedule or a trigger, and comes back as a draft to approve.
Going outside Microsoft
Reaching third-party systems means building agents: declarative agents with Copilot connectors and custom actions, or custom engine agents you host yourself.

Connecting an outside service is a workspace connection, and the agent uses it directly.
Questions people ask
- Is this about GitHub Copilot?
- No. This page is about Microsoft 365 Copilot, the assistant inside Word, Excel, Outlook and Teams. Kylon is not a coding assistant, although an agent can read a repository and draft a pull request for review.
- Can we use both?
- Yes. Copilot stays in the Office files. Kylon takes the work that crosses tools and needs more than one step.
- Does anything get sent or saved automatically?
- Sensitive actions wait for approval before they execute, and agents only see and touch what you allow.
- How is Kylon different from Microsoft 365 Copilot?
- Copilot works inside the Office file you have open, on the Microsoft data behind it. Kylon takes a request that crosses several tools, carries it out across them, and brings the result back into the thread for someone to approve.
- Does Kylon work outside Microsoft tools?
- Yes. Kylon connects to services directly, including Gmail, Slack, Notion, GitHub, Salesforce, HubSpot, Jira and Google Sheets, alongside the Microsoft ones.
- What does Kylon cost?
- Kylon is a paid workspace. Current plans are on the pricing page.

A better draft is not a finished task.
Keep Copilot for the document. Put an agent on the part that crosses tools and still needs a person to approve it.
