While the tech giants prepare their responses to the ChatGPT emergency, several startups have launched search engines with chat interfaces similar to the bot. They include You.com, Perplexity AI, and Neeva. The tools they have built illustrate both the potential and the challenge of adapting ChatGPT-style technology to search. You.com, founded by Richard Socher, an expert on language and AI, can provide answers through a chat interface. The responses come with citations, which can help a user track down the origins of a piece of information.
