Perplexity is developing an AI-powered search engine that leverages third-party large language models but own Web-crawler, website index and ranking algorithm. Through a conversational interface, Perplexity allows users to ask clarifying questions and receive contextual answers. All responses are accompanied by links to online sources to ensure transparency and verifiability. The company is also developing its own browser, Comet Assistant, which can answer questions based on the context of a webpage and browsing history, as well as perform agent tasks on websites (such as registering, ordering booking tickets, ordering a taxi, etc.). The company also provides search API and an enterprise version for searching internal knowledge. Perplexity regularly becomes the target of lawsuits for unauthorized use of content.
