About this tool
Basic swaps only the most common letters (a→4, e→3, i→1, o→0); medium adds more (s→5, t→7, g→9); advanced pushes further into multi-character substitutions (h→|-|, m→|\/|, w→\/\/ and more). It's purely a text substitution — there's no single "correct" leet speak, just widely recognised conventions.
