Frequently asked questions

Does it do currency?

Yes — it produces a 'Dollars and nn/100' cheque-style line in title case.

Decimals and negatives?

Both are supported, including a spoken 'point' for decimals and 'negative' for minus.

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.
