I got tired of calculator sites that hide a ten-second answer behind pop-ups, signup walls, and autoplaying ads. So I built tools that do one job per page and run entirely in the browser. No account, and nothing you type gets stored or sent anywhere. There are 70 of them now. Money side: salary increase (yearly/monthly/biweekly/hourly), credit card payoff, personal loan, CD interest, HELOC, mortgage refinance. Developers get a regex tester, subnet calculator, and JSON formatter.
