About KoguNavi
KoguNavi is a tiny toolbox for everyday cleanup tasks. It helps you format, convert, count, and tidy small bits of data without turning the job into a whole project. KoguNavi is growing first around Japanese forms, dates, text cleanup, and character issues that come up in everyday work.
