Perplexity has launched its Comet AI browser on Android, expanding the AI-centric browsing experience it first introduced on desktop in July. The mobile version brings nearly all of the desktop browser’s capabilities to smartphones, including AI-powered search, voice interaction, and deep reasoning across multiple tabs.
Android users can set Perplexity as their default search engine and even “mention” tabs to ask the assistant questions. The voice mode allows users to ask questions about all open tabs at once, and the browser can summarize information across them. Comet can also research and shop on the user’s behalf while showing exactly what actions the assistant is taking. An in-built ad blocker is included as well.
Perplexity says more features are coming soon. In the next few weeks, the company plans to add a conversational agent that can search across websites and take actions, shortcuts for quick tasks, and a fully featured password manager. Earlier this month, the company upgraded its desktop Comet Assistant to handle more complex, longer-running tasks, such as transferring website data into spreadsheets.
While the browser is debuting on Android first, Perplexity says an iOS version is on the way. The company prioritized Android due to high demand from carriers and device makers looking to integrate Comet, though it has not yet announced any partnerships. Earlier this year, Perplexity partnered with Motorola to preload its app on certain devices, but it remains unclear whether that deal will extend to the Comet browser.
AI-powered browsers are becoming a competitive space, with OpenAI, Opera, and The Browser Company, now owned by Atlassian, also offering AI-driven browsing experiences. Most remain focused on desktop, and Arc Search, launched last year for mobile, has seen few updates. Meanwhile, The Browser Company has shifted focus to its new browser, Dia, which still lacks a mobile version.

As AI browsers aim to challenge Chrome and Safari, security concerns continue to grow. Experts warn that AI agents may introduce new vulnerabilities. In October, Perplexity acknowledged these risks, noting that agent-based browsing will require rethinking security from the ground up.
