Developer builds ruleset to strip AI writing patterns from AI-generated text
A developer published a post on DEV Community describing a tool called Alchemy, a Markdown-based ruleset designed to remove telltale AI writing patterns from AI-generated content. The tool targets recurring signals such as em-dash overuse, filler phrases like 'in today's fast-paced digital landscape,' and words like 'delve' and 'robust' that research shows spiked sharply in frequency after ChatGPT's release. Its design draws on empirical sources, including a 2025 study by Kobak et al. finding 'delve' appeared at roughly 28 times its pre-ChatGPT rate in biomedical papers, and Pangram Labs data on inflated phrase frequencies. Alchemy works by flagging density of co-occurring tics rather than penalising any single word, and integrates with AI coding agents via a single init command. The tool is MIT-licensed and available on GitHub for anyone to read or adapt.
