IP protection firm Podqi tested ChatGPT, Gemini, and Perplexity with 6,795 shopping-related prompts across 151 brands and found all three engines cited and surfaced fake brand-impersonating websites, with Perplexity performing worst at 15% of answers containing risky sites. The study exposes systemic gaps in AI search around brand authenticity and e-commerce referral safety; Perplexity said it never claims 100% accuracy.
