WHAT YOU GET

Your computer has a problem. Another computer can fix it.

Yes, it is an AI fixing your PC, and we would rather be upfront about it. Describe the problem the way you would to a friend who is good with computers. Diagnosly does the digging, shows you the plan, and only changes something once you say so.

Clear, reviewable fixes.

Every step is shown before it runs, so you know exactly what is about to change.

A safety net first.

Before it makes a risky change, Diagnosly creates a Windows restore point and checks it worked, so there is something to go back to.

HOW IT WORKS

Describe it. Approve it. Fixed.

Tell Diagnosly what is wrong in your own words. It investigates, shows you the plan, and fixes it once you say yes. Here is the kind of thing it handles.

FOR TEAMS

Teach Diagnosly your company.

Looking after more than one PC? Diagnosly for teams runs the same engine across a whole fleet. Drop a single personality.md file in your repo to set your tone, boundaries, runbooks and escalation policy, and every device behaves accordingly. See Diagnosly for teams →

  • Define tone, formal for finance, casual for design, blunt for SREs.
  • Set guardrails, never run on prod hosts, always ask before BitLocker, no scripts touching C:\\Windows.
  • Encode your runbooks, point at internal Confluence URLs, KB IDs, on-call rotations.
  • Scope by team or tenant, Acme Sales gets one persona, Acme Engineering gets another.
