Thanks - sounds like a fun project!
Given that you've built your own coding tool, I assume this is as much about testing what AI can do as it is about the project itself? Is it a clear win as far as productivity goes?
I'm most interested in building cool projects, and I have found AI to be a major multiplier to that effort. One of those cool projects was a custom coding tool, which I now use with all my projects, and continue to polish as I use it.
As far as productivity, it's hard for me to quantify, but most of these projects would not be feasible for me to pursue with my limited free time without the force multiplier of AI.
