What superscript text is
Superscript letters sit above the baseline, like the 2 in x squared. Unicode has a set of small raised letters, borrowed from phonetic notation, which this generator uses.
Almost every lowercase letter works
Every lowercase letter has a tiny version except q, which stays normal size. Digits 0 to 9 work too, and so do the plus, minus, equals and bracket symbols, which makes it useful for small sums.
Capitals have gaps
Some capital letters have a tiny version and others do not. Where one is missing, the generator uses the tiny lowercase letter, so you may see a lowercase shape in a word that started in capitals.
For decoration, not for facts
Tiny text is hard to read and may not display in old fonts. Do not use it for anything people must be able to read, such as a price or a warning.
