AI Content Detection & Readability
TL;DR
Analyzes content for AI authorship signals (trigger words, em dashes, burstiness) and readability scoring (Flesch), sentence rhythm, E-E-A-T experience signals.
Explain Simply
AI-written content has telltale habits — overused fancy words, monotonous sentence rhythm, and em dashes everywhere. This check spots those patterns and scores how natural your content reads.
Content Quality Check combines two analysis layers:
1. AI Slop Detection: scans for 26 trigger words (delve, robust, leverage...), em dash density, passive voice percentage, sentence burstiness (length variance), and common AI phrases.
2. Readability & Structure: Flesch Reading Ease (55-75 optimal, +31% AI citation rate), summary/Key Takeaways box, FAQ section, question-format H2 headings, and first-person experience signals (E-E-A-T).
Based on claude-blog quality-scoring.md and ai-slop-detection.md (MIT, AgriciDaniel).
⚡Why It Matters
Google's December 2025 Core Update penalizes 'AI consensus content'. AI search engines (ChatGPT, Perplexity) favor natural writing with real experience and good structure. Flesch 60-75 increases AI citation rate by 31%.
