Also I just wrote evals for software I wrote using software I wrote Having a good day
Personal software is INSANE in the age of AI I use mine to: - Manage my course videos/material - Use AI to help me write accompanying text - Use AI to transcribe my videos WHILE RECORDING Folks who know how to build have a crazy advantage
