Perplexity’s Comet AI Browser Finally Lands on iPhone in March 2026—But Be Ready to Pay for the Real Magic

After months of tantalizing Mac users with its AI-infused browsing experience, Perplexity AI has finally confirmed that its ambitious web browser, Comet, is set to make its iPhone debut on March 11, 2026. The announcement has sent ripples through the tech community, sparking both excitement and skepticism about whether this AI-powered challenger can truly unseat Safari as the default browsing experience on Apple’s mobile devices.

The Long-Awaited Mobile Arrival

Comet’s journey to the iPhone has been anything but straightforward. While Mac users have enjoyed early access to the browser since late 2025, the mobile version has remained elusive—until now. The browser is already available for preorder through the App Store, though eagle-eyed observers have noted that the iPad version appears to be lagging behind its iPhone counterpart.

This staggered release strategy isn’t uncommon in the tech world, but it does raise questions about Perplexity’s development priorities and whether the company is confident in its mobile implementation. The March 11 release date gives Comet just enough time to make a splash before Apple’s Worldwide Developers Conference (WWDC) in June, where the company typically unveils major iOS updates that could potentially overshadow third-party browser innovations.

What Makes Comet Different?

At its core, Comet functions like any other web browser—you can navigate to websites, bookmark pages, and manage multiple tabs. However, Perplexity’s pitch centers on something it believes sets Comet apart: artificial intelligence that’s not just bolted on as an afterthought, but woven into the very fabric of the browsing experience.

The company’s vision is compelling in theory. Imagine reading a lengthy news article and being able to ask Comet’s AI to summarize the key points, identify potential biases, or cross-reference claims with other sources—all without leaving the page. Need to compare product specifications across multiple e-commerce sites? Comet promises to handle that heavy lifting for you. Want to understand complex technical documentation? The AI assistant aims to break it down into digestible explanations.

This AI integration represents a significant departure from how browsers like Safari, Chrome, and Firefox have traditionally operated. While these established players have added AI features incrementally—think autocomplete suggestions or basic content summarization—Perplexity is betting that users want a more immersive, AI-first browsing experience.

The AI Advantage: Promise vs. Reality

The theoretical benefits of Comet’s approach are substantial. By having AI capabilities built directly into the browser, Perplexity argues that users can accomplish tasks more efficiently without constantly switching between tabs or copying and pasting information into separate AI tools like ChatGPT or Claude.

However, the practical implementation of this vision remains to be seen. AI-powered features in browsers have historically been hit-or-miss, often struggling with accuracy, speed, and privacy concerns. Comet will need to demonstrate that its AI can deliver reliable results consistently, especially when dealing with the messy, unstructured nature of the modern web.

Privacy advocates are also watching closely. AI features typically require sending data to cloud servers for processing, which could raise concerns about what information Comet collects and how it’s used. Perplexity will need to be transparent about its data practices to win over privacy-conscious users who might otherwise stick with Safari’s more established privacy protections.

The Safari Challenge

Any browser attempting to gain traction on iPhone faces an uphill battle, and Comet is no exception. Safari comes preinstalled on every iPhone, is deeply integrated with iOS features like Apple Pay, password management, and Handoff, and benefits from years of optimization for Apple’s hardware and software ecosystem.

Moreover, Apple’s App Store policies require third-party browsers to use the same WebKit rendering engine as Safari, meaning Comet won’t have any inherent speed or compatibility advantages over Apple’s browser. The playing field is technically level, but Safari’s default status gives it an enormous advantage in user retention.

Comet’s AI features will need to be genuinely transformative to convince users to download a new browser, set it as their default, and potentially pay for premium features. The bar for “good enough to switch” is exceptionally high in the browser market, where users tend to stick with what they know.

The In-App Purchase Question

Perhaps the most telling detail in the announcement is the implication that Comet’s best features will require significant in-app purchases. This monetization strategy suggests that Perplexity views Comet not just as a tool for browsing the web, but as a platform for delivering AI services that users will pay to access.

The economics of this approach are interesting. AI processing is expensive, requiring substantial computational resources that don’t come cheap. By charging for advanced features, Perplexity can potentially offer a more capable AI experience than competitors who rely solely on advertising or data collection for revenue.

However, this strategy also creates a potential barrier to adoption. Users who download Comet expecting a free alternative to Safari might be disappointed to discover that the AI features they were excited about require ongoing subscriptions or one-time purchases. The phrase “maybe make it better than Safari” in the announcement hints at this uncertainty—Comet’s superiority isn’t guaranteed, it’s conditional on users being willing to pay for it.

The Broader Context: AI’s Browser Moment

Comet’s arrival represents part of a larger trend in the tech industry: the race to integrate AI into everyday tools and make them more intelligent and proactive. Browsers, as one of the most frequently used applications on any device, are natural targets for AI enhancement.

Google has been experimenting with AI in Chrome through features like “Help me write” and improved tab organization. Microsoft has integrated Copilot deeply into Edge. Even Apple is reportedly working on more sophisticated AI features for Safari in future iOS versions. In this context, Perplexity’s Comet is both a participant in and a challenger to the established order.

The success or failure of Comet could influence how other companies approach AI integration in their browsers. If users embrace Comet’s approach, we might see a wave of AI-first browsers competing for attention. If it flops, companies might retreat to more conservative AI implementations that don’t require users to change their habits as dramatically.

What’s Next for Comet?

With the March 11 release date approaching, all eyes will be on how Comet performs in the real world. Early reviews from Mac users have been mixed, praising the innovative concept while noting occasional reliability issues and a learning curve for users accustomed to traditional browsers.

The iPhone version will face additional challenges, including adapting the interface for smaller screens and ensuring the AI features work smoothly on mobile devices where users often have less patience for slow or unreliable experiences.

Perplexity will likely need to move quickly to address any launch issues and demonstrate clear value over Safari. The company has indicated that the iPad version is still in development, suggesting that mobile strategy remains a work in progress.

The Verdict: Worth the Hype?

Comet represents an ambitious attempt to reimagine what a web browser can be in the age of AI. The concept is compelling, the technology is promising, and the timing aligns with growing user interest in AI-powered tools. However, execution will be everything.

The browser market is notoriously difficult to crack, especially on platforms like iPhone where the default option has massive advantages. Comet’s success will depend on whether its AI features are genuinely useful enough to overcome the friction of switching browsers and potentially paying for premium capabilities.

For now, the tech world will be watching closely when Comet launches on March 11. Whether it becomes a revolutionary new way to browse the web or another noble attempt that fails to gain traction remains to be seen. One thing is certain: the browser wars just got a lot more interesting.
