About the Subscript Generator
Chemistry teachers, students and science fans all hit the same wall: H₂O is easy to write on paper, impossible in a chat box. This generator converts your text into Unicode subscript characters, so chemical formulas, math indices and variable notation survive pasting into any plain-text field.
All digits (₀-₉), the math signs (+, −, =, parentheses) and seventeen letters have official subscript forms and convert automatically — enough for every formula from CO₂ to C₆H₁₂O₆. Letters without a Unicode subscript pass through unchanged.
