Utility tools are practical helpers that do not fit neatly anywhere else. Two of them work with sound. Text to Speech has your browser read text aloud, with voice and speed controls, and Speech to Text lets you dictate into your microphone and see the words appear in real time. Both rely on features built into your browser, so the available voices and how well dictation works can differ between browsers and devices, and your browser will ask for microphone permission.
The other tools tell you about your own setup. The Screen Resolution Checker shows your screen resolution, pixel ratio and browser viewport size, which is handy when you are testing a layout or reporting a display problem. What Is My User Agent shows your browser's exact User-Agent string, often requested by support teams.
The IP Address Lookup is different from most tools on this site. To find your public IP address and its approximate location, it uses an outside service, so a request leaves your browser. The location is approximate and may point to your provider's area rather than your street.
