Perplexity AI, backed by Nvidia, is negotiating with mobile manufacturers to pre-install its new Comet browser on smartphones. CEO Aravind Srinivas highlighted the challenges, stating, "It's not easy to convince mobile OEMs to change the default browser to Comet from Chrome." Currently in beta for desktops, Comet integrates AI for tasks like email querying and meeting scheduling. With a $14 billion valuation, Perplexity aims to reach "tens to hundreds of millions" of users by next year.
