The researcher tested seven human-written texts at four levels of LLM-assisted proofreading from three LLMs, confirming that free detection tools frequently misclassify lightly edited human writing as AI-generated.", "body_md": "A short one today.\n\nI applied to a fellowship last year, used an LLM to check my punctuation - wrote the disclaimer prominently as required - and later discovered the same text scored between 40% and 100% AI-generated on free detection tools.\n\nI didn’t let it go. When have I ever?\n\nSo, I tested 13 free AI detection tools on seven human-written texts at four levels of LLM-assisted proofreading from three LLMs (wiping sweat of forehead).\n\nThe result: a published paper [SSRN](https://papers.ssrn.com/sol3/papers.cfm?abstract_id=7073158). It says what I suspected but needed to prove.\n\nRead it and let me know what you think.", "url": "https://wpnews.pro/news/llm-assisted-proofreading-a-study-of-the-effectiveness-of-13-free-ai-detection", "canonical_source": "https://forum.effectivealtruism.org/posts/XAyBcxNrq9A9PENcw/llm-assisted-proofreading-a-study-of-the-effectiveness-of-13", "published_at": "2026-07-24 10:11:04+00:00", "updated_at": "2026-07-24 10:40:38.142463+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-ethics", "ai-policy", "large-language-models"], "entities": ["SSRN"], "alternates": {"html": "https://wpnews.pro/news/llm-assisted-proofreading-a-study-of-the-effectiveness-of-13-free-ai-detection", "markdown": "https://wpnews.pro/news/llm-assisted-proofreading-a-study-of-the-effectiveness-of-13-free-ai-detection.md", "text": "https://wpnews.pro/news/llm-assisted-proofreading-a-study-of-the-effectiveness-of-13-free-ai-detection.txt", "jsonld": "https://wpnews.pro/news/llm-assisted-proofreading-a-study-of-the-effectiveness-of-13-free-ai-detection.jsonld"}}
