AI answer volatility index
AI answers are not stable rankings — the same question gets a different answer tomorrow. This index measures how much each engine's answers changed day over day across real tracked prompts: consecutive answers to the same question are compared on which brands they mention and which sources they cite. 0 = identical, 100 = completely rewritten.
