Perplexity AI, a search engine powered by artificial intelligence, is introducing advertising to its platform to generate revenue and become financially sustainable. The advertising will be presented in a less intrusive way than traditional search engine ads, using formats like sponsored follow-up questions and clearly labeled "sponsored" content. Perplexity plans to carefully monitor user feedback to refine its advertising model and ensure it does not compromise the platform's commitment to providing unbiased information. This move signals a shift in the AI-powered search industry as companies focus on building sustainable business models while balancing revenue generation with user experience.
