Is your content AI-citable? Paste any text and get an instant Citability Score. See which passages AI engines would cite — and which they’d skip.
Citability Score measures how likely AI search engines (ChatGPT, Perplexity, Gemini) are to cite your content in their answers. It evaluates AI-specific citation factors like passage quality, factual density, and source attribution. It is NOT an SEO score.
Surfer optimizes for Google rankings (keyword density, NLP terms, heading structure). Citability Score optimizes for AI engine citations (passage length, self-contained answers, entity density, structured claims). Different goals, different metrics.

A passage is a paragraph-sized chunk (optimally 134-167 words) that AI engines evaluate as a potential citation. Think of it as a self-contained answer block that can stand on its own in an AI response.
