## About this site
Tools Guru publishes 106 single-purpose web utilities that run inside the visitor's
browser. There is no account, no upload step and no paid tier. Ten tools require a
network call because they depend on live third-party data (currency rates, weather,
nutrition, recipes, AI image generation, HD background removal, speech transcription,
quiz generation, IP lookup, speed test); every other tool works with no connection.

Calculators are implemented from primary sources (WHO, RFC specifications, published
financial formulas) and verified against an independent reference implementation
before release. Finance and health tools carry explicit limitation notices and are
educational estimators, not professional advice.
