Perplexity AI Reaches 50M Monthly Active Users After Conversational Search Redesign

AI search startup Perplexity has crossed 50 million monthly active users following a major product redesign introducing conversational follow-up threads, source credibility scoring, and a new 'deep research' mode for multi-step queries. The growth represents a 2.5x increase year-over-year and places the company as the most-used AI-native search product globally. Perplexity is expanding its advertising revenue program after strong uptake of its Pro subscription tier.
