Who runs DailyCalcWorks
DailyCalcWorks is a Book AI Studio product, operated by BrightSpan Holdings LLC. Questions, corrections, and tool requests go to admin@bookaistudio.com, and a person reads them. If you find a wrong answer on this site, that inbox is the fastest way to get it fixed.
How the tools are built and checked
Every tool starts from the standard formula for its job — the same math used in classrooms, banks, kitchens, and workshops. Each tool page shows that formula in plain words, works a full example with real numbers, and answers common questions, so you can check any result yourself. The calculation code is covered by automated tests that compare the tools against known answers, and when a formula depends on something that changes, like a coverage rate for paint, the page labels the result an estimate. Health tools are estimates for general information only and are not medical advice.
