About these tools
This collection covers the tasks you'd normally need separate apps for. Need to measure something on your screen at actual physical size? The Online Ruler uses your display's true pixel density to render centimeters, millimeters, and inches accurately. Need to hit a word limit? The Word & Character Counter gives you live word counts, character counts, sentence and paragraph breakdowns, and an estimated reading time the moment you start typing.
Every tool here is built on the same principle: open it and use it immediately. No account required, nothing to install, no data sent anywhere. Whether you're a student hitting an assignment limit, a designer checking print dimensions, a developer standardizing variable names, or a project manager counting business days — there's a tool here for you.
