Frequently asked questions
Can I generate many at once?
Yes — set a count and it produces that many values in one go, up to a few hundred.
Is it private?
Every calculation happens on this page, in your own browser. Your input is never sent to a server, never logged and never used for training — which also means the tool keeps working when you are offline.
