I love AI side projects, it allows for quick iteration and finishing on ideas that weren't feasible due to time constraints before. I just made one yesterday/today.
I used Magit before and during the making of this I found out GitUI exists too but I think it's pretty powerful if the tool doesn't do exactly what you want and are opionated you can tailor your tools the way you want to.
