Perplexity Comet Lands on iPhone: The AI Browser That Replaces Google Is Free
Perplexity Comet is now free on iPhone as of March 18, 2026. This agent-native AI browser summarizes, compares, books and buys — all without leaving the interface.
After Mac and Android, Perplexity Comet is finally available on iPhone — for free — as of March 18, 2026. This isn't a browser with a chatbot bolted on. It's a browser where AI acts, books, compares and summarizes at every step of your browsing. Perplexity bets on subscriptions instead of ads — a radical wager against Google.
Comet Isn't Chrome With a Chatbot — It's the Opposite
In Chrome, Safari or Edge, AI is an option. A side panel. A button you forget about. In Comet, it's reversed: AI is the primary layer. The browser is the agent's interface.
The difference is concrete. You type: "Find me a well-rated Italian restaurant in Lyon that's open tonight." Chrome returns a list of blue links. Comet acts. It cross-references reviews, checks hours, suggests three options and can book directly — without leaving the page.
This is what Perplexity AI calls an agent-native browser: a browser designed from the ground up with AI as the core engine, not an add-on. Aravind Srinivas's AI assistant doesn't just answer your questions. It executes tasks.
What Comet Does That Safari and Chrome Don't
Comet's features go far beyond basic AI search.
Instant page summaries. You open a 3,000-word article. Comet summarizes it in three sentences. No third-party extension needed.
Persistent context across tabs. Traditional browsers forget what you were doing in the previous tab. Comet maintains a conversation thread (the history of your exchanges with the AI) from tab to tab, session to session.
Shopping and bookings without switching apps. Comparing products, booking a restaurant, buying a ticket — it all happens inside Comet. No need to jump between Chrome, Google Maps and the App Store.
Built-in ad blocker. Native. No extension to install. Pages load faster and the experience stays clean.
Voice control. You talk to Comet the way you'd talk to Siri — except Comet understands the context of your current browsing session.
Smart tab management. Comet organizes your tabs by topic and conversation thread. No more chaos from 47 open tabs.
Free on iPhone — After Costing $200/Month
Comet's pricing history tells the story of Perplexity AI's strategy.
Summer 2025: Comet launches on Mac. Exclusive to Perplexity Max subscribers at $200/month. A premium product for early adopters. November 2025: Android launch, free. March 2026: iOS arrival, free. The signal is clear — Perplexity wants critical mass on mobile to compete with Google.
The iOS launch hit two delays. Originally announced for March 11, 2026, it was pushed to March 13, then March 18. According to MacRumors, the final version has been live since March 18.
Comet is free with in-app purchases. Two plans are available:
- Perplexity Pro: €22/month or €229/year
- Perplexity Max: €229/year
Requirements: iOS 18.0 minimum. Size: 349.8 MB. No iPad version announced yet.
And crucially: no ads. Unlike Google Chrome, Perplexity relies exclusively on subscriptions. No advertising model.
Security: Human-in-the-Loop on Sensitive Actions
A browser that can buy, book and send emails on your behalf raises an obvious question: how do you prevent things from going wrong?
Perplexity built in a human-in-the-loop system (mandatory human oversight). For critical actions — sending emails, account changes, purchases — Comet requires mandatory human confirmation. Even when no risk is detected.
It's the same philosophy as Claude Dispatch, launched two days earlier by Anthropic: responsible AI agents keep humans in the loop. No silent execution. No surprises.
Perplexity also details its strategy against prompt injection attacks (attempts to manipulate AI through hidden instructions in web pages) in a dedicated security article.
Comet vs Chrome vs Safari vs Edge — Who Is Each One For?
Comet doesn't kill Safari. It doesn't replace Chrome for everyone. But it targets a specific segment: users who want to delegate tasks to AI without juggling five applications.
| Browser | Native AI | Acts (books/buys) | Ad Blocker | Price |
|---|---|---|---|---|
| Perplexity Comet | ✅ Agent-native | ✅ Yes | ✅ Built-in | Free |
| Chrome + Gemini | ⚠️ Add-on | ❌ No | ❌ No | Free |
| Safari + Siri | ⚠️ Add-on | ⚠️ Limited | ❌ No | Free |
| Edge + Copilot | ⚠️ Add-on | ⚠️ Limited | ❌ No | Free |
| Dia | ✅ Agent-native | ✅ Yes | ✅ Yes | Freemium |
Chrome remains unbeatable for the Google ecosystem. Safari is the natural choice for Apple integration. Edge suits Microsoft 365 users. But for AI browsing — integrated AI search, autonomous actions, persistent context — Comet and Dia are ahead.
According to Clubic, early hands-on testing confirms Comet's potential, even if some fine-tuning is still needed.
In summary:
- Perplexity Comet is available for free on iPhone since March 18, 2026, after Mac (summer 2025) and Android (November 2025).
- It's an agent-native browser: AI summarizes, compares, books and buys directly in the interface, without switching apps.
- Comet includes a built-in ad blocker and integrated voice control.
- For sensitive actions, human confirmation is mandatory — Perplexity keeps humans in the loop.
- Free with in-app subscriptions: Pro at €22/month, Max at €229/year — zero advertising.
Comet activates the idle resources of web browsing. All the time wasted switching between Chrome, ChatGPT, Google Maps and standalone apps becomes a single unified interface — AI absorbs the friction. On iPhone, in your pocket, for free. AI search no longer goes through Google. AI agents that shop for you now have their own browser. And the payment systems are ready for them. Idle browsing is over.
