Perplexity has launched its native Mac app, aimed at competing with established AI search applications like OpenAI's ChatGPT. The app, which is free with a Pro subscription option, enhances user experience with advanced features such as voice mode and file upload capabilities. Users can also browse conversation history and ask follow-up questions seamlessly. Earlier this week, Perplexity was reported to be seeking $500 million in funding to increase its valuation to $8 billion, amidst a cease-and-desist letter from The New York Times over alleged scraping issues.
