Perplexity AI made its artificial intelligence-powered browser, Comet, available generally and at no cost. Comet was launched in a limited release on July 9 and since then has had a waitlist joined by “millions of people,” the company said. The browser includes the Comet Assistant, which can help with research, meetings, code and eCommerce while the user is browsing the internet. Perplexity also announced in its blog post the launch of Background Assistants, which are AI assistants that can work in the browser, the inbox or the background. The company will also make Comet available as a mobile app “soon,” per the post. The browser is currently desktop-only. When introducing Comet in July, Perplexity said that the AI-powered browser “transforms entire browsing sessions into single, seamless interactions, collapsing complex workflows into fluid conversations.” By making Comet available for free, the company will be better able to compete with other AI-powered browsers, such as those available from Google, OpenAI and Anthropic. The first publishers to participate in Comet Plus, its service that gives users and their AI assistants access to participating publishers’ journalism and compensates the publishers for that access.
