Most tool websites bury you in pop-ups and force sign-ups before showing a result. We do the opposite: no accounts, no paywalls, no dark patterns. You type, you get your answer, you move on.
Privacy first. Every tool here is pure JavaScript running on your device. Your dates, numbers and text are never transmitted, logged or stored. Close the tab and they are gone.
Real explanations, not just answers. Each tool ships with worked examples, background you can trust, and a FAQ answering the questions people actually ask.
