AI Engines Disagree on 37% of Brand Recommendations — Your Visibility Depends on Which AI Users Ask

Key Findings

We tested 1,159 brands across all four major AI engines. 427 brands (37%) received different treatment from different engines — from complete invisibility on one to 100% visibility on another.

Each AI Has a Distinct "Personality"

• Perplexity (25.8%) — The generous recommender with the most brand mentions
• ChatGPT (24.4%) — The comprehensive lister with many alternatives
• Claude (21.8%) — The cautious analyst with lower sentiment scores
• Gemini (14.4%) — The selective curator with premium positioning

The Gemini Paradox

Gemini mentions the fewest brands but treats them the best: average rank #1.97 vs #3.50 for ChatGPT. 50% of Gemini mentions are primary recommendations.

Implications

Your brand's AI visibility isn't a single number — it's four different numbers that can wildly contradict each other. Testing only one engine gives you 25% of the picture.
