Perplexity AI Inc., the conversational search startup challenging Google Inc.’s dominance, has thrust its ambitious Comet browser into the mobile arena with a full launch on Android devices. Announced on November 20, 2025, the app arrives amid intensifying rivalry in the AI-augmented browsing space, extending Comet’s desktop capabilities to smartphones and positioning Perplexity as a direct threat to Alphabet Inc.’s Chrome and ecosystem.
Initially unveiled in July 2025 as an exclusive for Perplexity Max subscribers at $200 monthly, Comet evolved rapidly. By October, it went free worldwide on desktop, and now the Android version brings voice-activated AI assistance, task automation, and transparent agentic actions to mobile users. ‘Comet is the mobile browser for the new age of the internet,’ Perplexity posted on X, linking to its Google Play Store debut.
From Desktop Experiment to Global Rollout
The trajectory traces back to February 2025, when Perplexity CEO Aravind Srinivas teased Comet on X as a ‘new agentic browser.’ Early access rolled out experimentally to Max users in late September, with Srinivas noting, ‘Update Comet and try it out!
