Built by an admin, for admins
I've spent 8 years in IT, working across Active Directory, Microsoft 365 administration and PowerShell automation. Most of these tools started as scripts I wrote to stop doing the same job by hand.
AI Korp is where I clean them up, document them and give them away. Every script is plain PowerShell you can read before you run it. Nothing phones home.
