Perplexity Just Launched an AI Browser for iPhone. Google Chrome has been the default browser on most iPhones for years. Perplexity just decided that’s a problem worth solving.
Comet — Perplexity’s AI-powered browser — launched on iPhone today, March 18, after a one-week delay from its original March 11 release date. It’s already available on Mac, Windows, and Android. Now it’s on the device that matters most — the one in almost everyone’s pocket.
And the pitch is genuinely different from anything Chrome or Safari offers.
What Comet Actually Does
Comet isn’t just a browser with an AI chatbot bolted on. The entire experience is built around the idea that your browser should think alongside you — not just load pages.
Open any website and Comet can summarize it instantly. Start shopping and it compares prices without you having to open five tabs. Need to schedule something mentioned on a webpage? Comet can handle the calendar invite without leaving the page. Research a topic and it builds context across everything you’ve visited — remembering what you were looking for even when you’ve forgotten yourself.
The tagline — “boost your focus, streamline your workflow, and turn curiosity into momentum” — sounds like marketing. The feature list suggests they actually mean it.
Why the Delay Matters
Perplexity originally promised Comet for iPhone on March 11. It slipped a week. That delay either means the team wanted more polish before shipping — which is respectable — or there were last-minute issues with Apple’s App Store review process, which has a history of making AI app launches complicated.
Either way, it’s here now. And the fact that it’s already available on four platforms simultaneously signals that Perplexity is treating this as a serious product launch — not a beta experiment.
The Real Target Isn’t Chrome
Here’s the thing about calling Comet a “Chrome competitor” — it’s not really accurate. Chrome wins on familiarity, ecosystem, and the fact that it comes pre-installed. Comet isn’t trying to beat those advantages.
It’s targeting a specific type of user — the person who lives in multiple browser tabs, uses AI tools constantly, and is frustrated that their browser and their AI assistant still don’t talk to each other properly.
If you’re someone who has ChatGPT or Perplexity open in one tab while you work in another — Comet is designed to collapse those two things into one. That’s a compelling pitch for a growing number of people.
What Perplexity Is Actually Building
Comet for iPhone isn’t an isolated product. Perplexity also recently announced Personal Computer — an AI agent that runs locally on Mac and handles tasks autonomously across your entire desktop.
The pattern is clear. Perplexity wants to be the AI layer that sits between you and everything you do on your devices — browsing, research, scheduling, communication. Not a search engine you occasionally visit. An intelligent operating layer you never leave.
That’s a much more ambitious vision than a better search box. Whether they can execute it is the only question worth asking.
The Honest Catch
Comet requires trusting Perplexity with a significant amount of your browsing data — every page you visit, every search you make, every document you summarize. The AI gets smarter by knowing more about you. That’s the deal.
For people already using Perplexity daily, that trade-off probably feels reasonable. For everyone else, it’s worth thinking about before handing a new AI company full visibility into your internet life.
