Tripadvisor's AI review summaries dangerously downplay serious complaints, Which? investigation reveals

An investigation by consumer watchdog Which? found that AI-generated summaries of Tripadvisor hotel reviews are glossing over serious safety and conduct issues, describing a hotel sued for mass food poisonings as "spotless" and praising "friendly" service at a resort where guests reported sexual harassment. The AI summaries systematically downplayed major complaints including mold, lack of running water, and other hygiene failures.

Why it matters: As AI summarization tools become standard features on major travel platforms, this investigation exposes critical gaps in how AI handles nuanced consumer safety information—raising questions about liability and whether automated summaries should replace human-reviewed content on high-stakes decisions.
