About Miscellaneous
Miscellaneous covers the small utilities that don't fit neatly elsewhere: validating an email address's format, looking up your public IP and approximate location, reading your screen resolution and color depth, dumping browser and OS info for bug reports, a 1-minute typing speed test, and a quick-access notepad that auto-saves to local storage.
Support engineers ask for screen resolution, user agent, and IP when triaging issues — every value here is a click away. Job seekers use the typing test to measure WPM. The notepad is handy for jotting code snippets and meeting notes that you don't want to commit to a cloud service.
The IP checker performs a single, anonymous request to learn your public address; everything else runs in your browser using standard web APIs. Nothing is logged, transmitted, or persisted server-side.
