About

minchangyi.com is where I keep the small tools I built for myself. Each one started as something I needed once and got tired of re-doing by hand.

Every tool runs entirely in your browser. Nothing you type or drop in is sent to a server, because there is no server — the whole site is a folder of static files. Anything a tool remembers is saved on your own machine and disappears when you clear your browser data.

Free to use, no account required.
