How we measure this
Each benchmark runs the same standardized prompts across multiple leading AI systems, including ChatGPT, Claude, Gemini, and Perplexity. We use consistent, category-specific questions designed to surface genuine product recommendations — not sponsored results.
Responses are parsed to extract brand mentions, rank position, and frequency. We then analyze cross-model agreement, identify which brands consistently appear in top positions, and flag where AI outputs diverge from marketplace trends.

Your competitors are showing up in AI results. Are you?
The air purifier market is locked at the top by Levoit, Coway, and Blueair in AI recommendations. Premium brands like IQAir, Austin Air, Molekule, and Aprilaire are largely invisible despite strong retail/clinical positioning. If your air purifier brand isn't in the top 3, you're fighting for fragmented per-model visibility. Niche premium brands like Rabbit Air can win specific AI surfaces (Perplexity) but lack broad authority. The DIY/community-driven category (Corsi-Rosenthal boxes) is becoming a real competitive force visible only in Claude.
