I disliked the ad-supported Sudoku apps I tried so I created my own ad-free PWA and it also teaches solving strategies and can auto notate and auto solve.

I disliked the Python/Colab approach to learning/experimenting with ML, so I created my own languages and tools via Claude.

I didn't want to learn/code Verilog directly for programming inexpensive FPGAs, so I developed my own higher-level language and tools via Claude and Codex.

I disliked having to set all the controls on function generators and digital scopes so I developed scripts to do that over USB instead of via buttons, via Codex.

I disliked using desktop video editing tools, so I used Claude to generate all sorts of video editing CLI and desktop tools that are more automated, less manual.
