Perplexity’s AI-first browser, Comet, is finally making the jump to the iPhone, with an App Store listing confirming a March 11, 2026, release date for devices running iOS 18 or later. For a company that has built its reputation on fast, citation-backed answers, this move pulls its most ambitious product straight into the one place people already instinctively reach for when they want to “just quickly check something”: their phone’s default browser slot.

On the App Store, Comet is billed as “an AI-powered browser that acts as a personal assistant and thinking partner,” and that’s not just marketing copy. The idea is that instead of juggling dozens of tabs, apps, and screenshots, you live inside a single interface where the browser understands what you’re trying to do and quietly handles the boring parts in the background. Perplexity pitches it as a way to boost focus, streamline your workflow, and “turn curiosity into momentum,” whether that means researching a trip, comparing products, or blasting through admin tasks that usually demand three different apps and a lot of copy-paste.

If you’ve missed the Comet story so far, this isn’t some experimental side project suddenly showing up on iOS. Perplexity originally launched Comet as a desktop browser built around AI-native browsing, not just AI sprinkled on top. It runs on Chromium, integrates directly with Perplexity’s own search engine, and has already rolled out to Windows and macOS, with Android following later. Along the way, it has shifted from a premium perk for paying power users to a more mainstream product, including a free tier that puts an AI “sidecar” right in your browser window to summarize pages, answer questions, and help you navigate sites without manually bouncing between tabs.

On iPhone, the experience Perplexity is teasing looks very familiar if you’ve seen Comet on desktop or Android—but compressed into a vertical, mobile-first format. Screenshots on the App Store listing show a clean browser view with an integrated assistant panel that can summarize whatever’s on screen, answer follow-up questions in natural language, and execute actions like booking hotels or completing purchases directly from the same interface. The company describes this as “unified AI search, instant context, and automation across every site,” with the assistant sitting inside the browser rather than being a separate chatbot you have to copy links into.

The real shift is conceptual: Comet is built for what Perplexity calls “agentic search.” Instead of you searching, clicking, scanning, and stitching together information, the browser is meant to interpret your intent, maintain context across pages and sessions, and then do the legwork—multi-step actions, comparisons, email drafting, booking, and other routine tasks—while you stay in conversation with the assistant. In practice, that can look like opening a product page, asking the assistant to compare it with three competitors, having it extract pros and cons, then asking it to watch price drops or suggest better alternatives, all without opening a separate research tab mess.

For iPhone users, that vision arrives with some fine print. The App Store listing shows Comet as a free download with in-app purchases, and coverage has already hinted that you should expect to pay if you want to get beyond what Safari, plus a separate AI assistant, can already do. Perplexity hasn’t detailed the exact pricing for the iOS build yet, but across desktop and Android, the model has been straightforward: a free tier with reasonable caps for everyday browsing, and paid plans or promotions (like a year of Pro access via partner offers) for heavier workloads and more automation.

Feature-wise, Comet on iOS is stepping into familiar territory—but with a different philosophy. Like on desktop, the iPhone version promises a built-in ad blocker to cut down on spammy pages and pop-ups, page-aware summaries that work on whatever you’re currently viewing, and the ability to “chat with your tabs,” including via voice on platforms where that’s supported. It’s designed for people who do a lot of research, comparison shopping, or workflow-heavy tasks on their phone and are tired of bouncing between Safari, email, notes, screenshots, and separate AI apps. Instead, you get a single canvas where your browsing history, current page, and AI assistant all live together and remember what you were doing.

There’s also a subtle but important Apple angle here. By requiring iOS 18 or later and launching as a standalone browser rather than just a companion to the existing Perplexity app, Comet is positioning itself to compete more directly with Safari and Chrome for that coveted spot on your dock. On macOS, Comet already behaves like a full browser with support for standard extensions and a familiar Chromium-based UI; the iPhone launch takes that same “AI-first browser” identity and puts it in your pocket. If you’re the type to default to Safari because “it’s just there,” Perplexity is betting that integrated AI, agentic workflows, and less tab chaos might be enough to get you to switch—or at least to give Comet the prime real estate of your home screen for a while.

Of course, an AI-native browser living this close to your everyday digital life comes with the usual questions. Comet’s App Store listing flags that it may collect data such as financial information, location, contact details, browsing history, usage data, and diagnostics—though it notes this data is “not linked” to your identity, and points users to Perplexity’s privacy policy for the fine print. Security researchers have already probed Comet’s model on other platforms, highlighting potential attack vectors and raising questions about how AI-infused browsers handle sensitive data, advertising, and SEO in a world where users increasingly “chat” with web pages instead of visiting them in the traditional sense. Those debates will almost certainly accelerate once Comet lands on the iPhone, where browser choice is less fragmented and any challenger stands out more starkly against Safari.

What’s clear is that March 11 is shaping up to be a milestone not just for Perplexity, but for the broader idea of what a browser is supposed to be in the AI era. Comet has already gone from limited release to global desktop rollout, then to Android, and now finally to Apple’s most personal screen. For some users, it will just be a more helpful way to read the web. For others—especially folks already living in AI tools all day—it might become the default place to think, plan, and get things done. And once an AI browser feels at home on iOS, it becomes much harder to argue that the future of the web lives only in tabs and URLs, rather than in assistants that understand what you’re trying to do and quietly move things forward while you just…ask.
