Perplexity has expanded its AI-focused browser to iPhone, completing the rollout of its Comet platform across desktop and mobile devices.

The app, now available through the Apple App Store, centres on an integrated AI assistant designed to change how users search and interact with web content. Rather than relying solely on traditional search results, the browser can generate answers by combining information from multiple sources.

On iPhone, Comet allows users to ask questions about the page they are viewing and receive summaries or explanations without navigating away. It can also surface related topics, making it easier to explore information in more depth within a single session.

A key addition is a hands-free voice feature that lets users interact with the browser using spoken commands. This includes asking questions about individual pages or across several open tabs. The system can also summarise content from multiple tabs at once, which is particularly useful for tasks that involve comparing information from different sources.

The browsing experience blends standard search results with AI-generated responses. Users can perform a quick search and then follow up with more detailed questions, all within the same interface. This approach aims to combine the speed of traditional search with the flexibility of conversational queries.

The mobile version also includes built-in ad blocking to reduce on-screen clutter. Users are able to choose between different AI models from providers such as OpenAI, Google and Anthropic, depending on their preferences.

Perplexity positions Comet as more than a conventional browser, describing it as a tool for research, planning and everyday tasks. Features are designed to help users gather information, compare options and complete actions without switching between multiple apps.

With the iPhone release, Comet now supports cross-platform continuity. Conversations and research started on desktop devices can be accessed on mobile, allowing users to continue where they left off.

Whether the AI-driven approach will be enough to draw users away from established browsers such as Safari and Chrome remains uncertain, but the launch highlights the growing push to integrate artificial intelligence more deeply into everyday web use.
