About Us

工具箱

ZHUEi is a free collection of online utility and calculation tools, designed to give everyone simple, fast and accurate everyday tools.

We provide dozens of common tools — license plate, traffic violation, currency exchange, loans, tax, weather, unit conversion, date calculation and more. All tools are free and require no registration.

Our mission: make everyday lookup and calculation simpler.

We do not store anything you enter: pure calculation tools run locally in your browser, and tools needing external data redirect you directly to the official website.
