Perplexity, the company behind the AI answer engine, has officially released the Android version of Comet, which it bills as the world's first AI-native browser[1]. The "ask, organize, act" experience praised in the desktop version now extends to smartphones, delivering a new mobile browsing experience with an always-on AI assistant. The Android release also includes voice-based search across tabs and a native ad blocker.

A Mobile Browser Rebuilt from the Ground Up

While most internet use has shifted to smartphones, Perplexity argues that traditional mobile browsers have failed to deliver value beyond simply "looking things up"[1]. The company points to three specific problems: information is fragmented and hard to organize, switching between apps is required to continue a task, and ads and pop-ups break concentration[1].

Rather than porting the desktop user interface as-is, Comet for Android was redesigned from scratch as a mobile browsing experience built around AI[1]. Users can set Perplexity as the default search engine, so browsing starts from a dialogue with AI[3].

Key Features of Comet for Android

At the center of Comet for Android is a built-in AI assistant that supports tasks without requiring page transitions or app switching[1]. Its main features fall into four areas.

First is the "Comet Assistant," which can be summoned with a single tap. It instantly supports questions, research, and task execution, and its enhanced reasoning ability makes the assistant's actions visible while allowing the user to intervene mid-process[1].

Second is a mechanism that lets users "converse" with their tabs. The Voice Mode popular in the Perplexity app is also built into the Android version of Comet, allowing voice-based questions and searches across multiple open tabs[1].

Third is a summary of search results across tabs. Comet supports its signature "cross-tab information integration" feature, with AI summarizing the contents of all open tabs at once[1].

Fourth is a native ad blocker that the company describes as industry-leading. It automatically blocks spam ads and pop-ups, and trusted sites can be added to a whitelist for display[1]. According to Perplexity, Comet can also carry out research and shopping on the user's behalf[3].

Free to Use, with an iOS Version in Preparation

The product is named Comet (Android version), and it runs on Android[1]. It became available in November 2025, with the U.S. announcement made on November 20[1][3]. It is free to use, with some premium features available[1]. The app can be downloaded from the Google Play Store[1].

Looking ahead, Perplexity has indicated plans to add, within a few weeks, a conversational agent that searches and takes actions across multiple sites, shortcuts for quickly directing the assistant, and a full password manager[3]. The company also says an iOS version for Apple devices is planned for release soon[1][3].

Summary

Perplexity has extended Comet, a browser with an always-on AI assistant, to Android, bringing major desktop features such as voice-based cross-tab search and ad blocking to smartphones. With the browser distributed free of charge, attention now turns to how far an AI-centered mobile browser can change everyday browsing.
