I've found it to be helpful as well in many situations. Just this morning, I was updating an old Delphi XE program that needed to get a list of available drives and forgot what the procedure was called. Sure, I could've looked it up but Claude reminded me of GetLogicalDriveStrings much quicker.
Earlier this week, I wanted to try out Claude Code on my Windows machine. I learned it required Linux and didn't work on my currently installed WSL version 1. (The web-based) Claude helped me figure out which version of WSL I had, install WSL 2, then even though it was installed, WSL 1 was still the default so it helped me change that. Then, I had to go through a similar process with nodejs and npm. I learned several new "wsl" commands and got it up and running. It would've taken me many hours hunting down forums and blog posts to put all those pieces together--I probably would've given up.
It's not great at writing whole programs or untangling a huge library of code but it can sure save time in many instances.
