LLM cliché highlighter
Simon Willison published the LLM cliché highlighter, a tool designed to detect and highlight common clichéd phrases in text that frequently appear in language model outputs. Users can paste text into the analyzer to identify patterns like "no X, no Y" chains, "sit with that," "you already know," and other LLM-generated expressions. The tool includes toggleable pattern detection and context-aware sentence highlighting, along with pattern counts, match listings with quick navigation, and runs entirely in the browser with localStorage support for persistence. Willison stated he got frustrated reading yet another article crammed with the clichés of LLM-generated writing—"no fluff, no filler, no jargon" type stuff—so he had Fable 5 vibe code up this app for highlighting ten common patterns that show up in that sort of writing. The tool was posted on 17th July 2026.
Helps developers identify and avoid overused LLM phrasing in their own or others' writing.
