Does my writing sound like AI? Claude ranked my red flag habits

PCWorld explores how human writing can exhibit AI-like characteristics, with an author using Claude Sonnet 4.6 to analyze their own content for artificial intelligence tells. Parenthetical asides emerged as the top AI indicator with 67 instances across 11,700 words, followed by em dash overuse and filler words like "actually." Despite these patterns, Claude rated the writing as mostly human, scoring only 3 out of 10 on AI detection due to strong personal voice and varied sentence structures. What could be better than an em dash? They pepper my writing, adding dramatic pauses and emphasizing my biggest points.
