Perplexity's Comet Browser on Android

What happened

Perplexity introduced its AI-powered Comet browser on Android, expanding its availability from desktop to mobile platforms. This new application integrates smart summarisation, an ad blocker, and a voice mode. It features an AI Assistant capable of answering questions and executing user actions, alongside expanded reasoning for AI problem-solving and contextual summarisation across open tabs. The mobile version, redesigned for Android, is available without charge.

Why it matters

The deployment of an AI-native browser with integrated summarisation and an AI assistant on mobile introduces a new vector for information processing and data handling outside established enterprise browser controls. This increases exposure for IT security and compliance teams to potentially unmonitored data flows and AI-driven content generation, raising due diligence requirements for data governance and acceptable use policies. The integrated ad blocker may also reduce the effectiveness of existing network-level content filtering mechanisms, creating a visibility gap for network operations.
