Willison published a browser tool on July 17 that flags AI-writing tics at the sentence level with toggleable pattern detection: 'no X, no Y' chains, 'sit with that,' 'you already know,' 'is real and,' and 'worth naming' among roughly eleven patterns, with URL ingestion via r.jina.ai. The motivating example — 'no fluff, no filler, no jargon' — is itself the giveaway. Practical for anyone editing agent-generated copy before it ships under their own name.
