Beneath every line sits a stack of coloured rules. Each rule is one n-gram —
a run of 5–11 tokens — that the search engine found somewhere in a vast text corpus.
Rules overlap and nest: a 5-gram living inside an 8-gram simply sits on its own
lane, so a single stretch of prose can carry several at once. Colour marks rarity —
rust phrases are
nearly unique to this story, while
slate phrases are
corpus boilerplate. Hover any rule to read its matches.
