Perplexity uses natural language processing for precise, comprehensive responses. It sources information from multiple web sources and provides transparent references. Building on their recent rebranding by Smith & Diction, we embarked on a comprehensive design system and native UI overhaul, introducing an updated thread view and new features like the improved home experience, thread library and collections. We worked closely with Perplexity's design and engineering team, streamlining their development workflow and ensuring cross-platform consistency.
