I built Sub & Superscript after seeing text generators quietly replace unsupported letters with symbols that only looked similar. The result appeared complete, but the character itself had changed. This tool makes the choice explicit. Pick Superscript or Subscript, then choose Formulas & numbers or Tiny text. Formula mode keeps the base readable, so 6.02e23 becomes 6.02e²³. Tiny text shifts every character for which Unicode has a real match. If no match exists, the original character stays put. There is no signup and nothing to install. Type, copy, and paste into a document, slide, message, bio, or code comment. I would especially like feedback from people who write scientific notation, chemistry formulas, Discord messages, or profile names. What do you paste most often, and where does the result still look awkward?
