LLM cliché highlighter catches 'no fluff, no filler' writing

2026-07-18 · source:

The LLM cliché highlighter is a browser tool that flags ten common patterns typical of LLM-generated writing, such as 'no fluff, no filler, no jargon' constructions.

What it is

A small web app at tools.simonwillison.net built by Simon Willison after getting fed up reading yet another article full of stock LLM phrasing.

What it does

It scans pasted text and highlights ten recurring patterns typical of LLM-generated prose, then reports match counts and flagged sentences so you can see exactly where the clichés live.

Why it matters

If you're editing AI-drafted docs, PR descriptions, or blog posts before publishing, this catches the tells a human reviewer might skim past, which is exactly the kind of pattern this pipeline's own voice guidelines try to avoid.

How to use it

Paste any draft into the tool at the source URL and review the flagged sentences before you ship the text.
