It is Golden Week in Japan. It’s been a while since I get a full day off. Instead of creating an illustration, I decided to spend some time to use Claude.ai to write a productivity app for Windows. Before I knew it, a 2-hour vibe coding session turned into a full 8-hour manual coding session.

I initially used AI to help me write the code. As I tried to add more features, Claude started hallucinating and giving me incorrect code snippets, so I decided to write the code the old-fashioned way. Thanks to the template script written by AI, I didn’t have to waste time writing boilerplate code – I just dove into the existing code and added features along the way, with the help of the AutoHotKey documentation.

It’s good to know that I still haven’t lost my touch in programming. My current job doesn’t really have a good engineering culture, so I started to pick up a lot of bad corporate habits (like writing garbage code and focusing on “solution design” instead of writing maintainable code). I’m glad I still haven’t lost interest in programming completely. However, I need to take my art business more seriously.

I hope this little app would be helpful for people to keep track of their app usage on their Windows desktop. You can find the source code and downloadable .exe file here: https://github.com/laxa88/time-tracker
