Perplexity is a Swiss Army Knife for information discovery and curiosity, blending the capabilities of an AI-powered search engine with those of a chatbot. It indexes the web daily to provide fast and accurate answers to your questions, using large language models like GPT-4 and Claude 3 to understand queries and summarize relevant information. Perplexity offers two types of searches: Quick Search for basic answers and Pro Search that tailors responses to your needs and asks follow-up questions to refine its answers. The platform also allows users to upload documents and images, generate images or text based on their content, and organize searches into collections with shared prompts. While it excels at finding information from recent articles, Perplexity is not a direct replacement for traditional search engines or general AI chatbots and may require verification of its accuracy through external sources.
