FAQs
How is this different from search?+
Search answers a specific query; the directory shows everything at once, which is how you notice a tool you did not know existed.
Do I need an account?+
No. Every calculation runs without signing in; an account only stores favourites and saved results.
Do the calculations run on a server?+
No, in your browser. Nothing you type is sent anywhere unless you choose to save a result.
How often are new tools added?+
In large batches: the most recent hundred arrived as whole sections — gaming, sport, study, text, home, nature and business.
