Perplexity Launches Comet AI Browser on Android With Voice, Cross‑Tab Summaries and Built‑In Ad Blocker

The release targets a larger mobile audience with a redesigned, assistant-led experience, leaving distribution deals plus security safeguards as open questions.

Overview

  • The Android app brings most desktop features, including Perplexity as the default search engine, voice mode, questions that reference open tabs, and summaries across tabs.
  • Mobile-first tools add Expanded Reasoning for transparency into the assistant’s process and Contextual Summarization across open tabs, alongside a native ad blocker the company touts as highly advanced.
  • Perplexity outlines near-term additions such as a conversational agent that searches across sites, assistant shortcuts for quick actions, a full password manager, and browsing data sync, with an iOS launch planned.
  • The company cites interest from carriers and OEMs to include Comet on devices but announces no partner deals; an earlier Motorola preload covered the app, with no confirmation for the browser.
  • Perplexity previously acknowledged risks tied to agentic AI in browsers, noting that new attack patterns require rethinking security from the ground up.
