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
Microsoft 365 CopilotCopilot 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?
KylonAn agent lives in a room with the team, not inside one file, and works across whichever connected tools the task needs.
What it reads

One turn or a task

Going outside Microsoft

Where Copilot is the better tool

Copilot sits inside the Office files and the Microsoft data your company already has, and it needs no new place to live. Kylon is a separate workspace: you bring the tools and the context into it. If your work never leaves Word, Excel and Outlook, that is a real reason to stay where you are.

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.

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.
