About

We turn the rules and numbers in official notices into calculators and tables. An example is the day count for tax residency. When data has no official source, the page names where it comes from.

Each page lists its sources and the date of its last update. The calculation runs in your browser.

We only make pages for questions that current search results do not answer clearly, or answer in conflicting ways. We do not mass-produce similar pages.

An AI model makes the tools and the text. A separate, independent AI then checks them. No person reviews the pages.

For details, see the editorial policy and sources and how we check.
