YouTube is running an opt-in experiment called "Ask YouTube" that replaces the standard video-grid search with AI-generated text summaries, curated video segments with timestamps, and a persistent follow-up thread—letting users query complex multi-step topics like trip itineraries or historical events and refine results conversationally. The feature is available now through June 8 to US Premium subscribers aged 18+ via youtube.com/new; Engadget notes that early testing showed mixed accuracy, with some queries returning factually inaccurate summaries. Google says it plans to extend access to non-Premium users after the experiment.
