Perplexity releases its Comet browser with a built-in AI assistant and a native ad blocker for iOS and iPadOS, after launching it on Android in November 2025
Perplexity's Comet AI browser is coming to iOS and iPadOS today, four months after its previous launch on Android. The mobile browser comes with a built-in AI assistant …
Context & Ripple Effects
Comet began as a limited browser offering tied to Perplexity's premium plan, then shifted to a free, rate-limited product in a broader-access rollout. The iOS and iPadOS release extends that distribution strategy beyond the earlier Android launch.
The move also builds on Perplexity's prior iOS voice-assistant support, which brought conversational assistant features to its iPhone app, by placing an assistant directly inside the browsing surface.
First-order effects
- iOS and iPadOS users can now use Comet as a mobile browser with Perplexity's assistant embedded in the browsing flow, rather than only accessing the company's assistant through its standalone app.
- Comet's native ad blocker immediately changes how pages are rendered for its users, reducing exposure to publisher-served advertising within the browser.
Second-order effects
- Perplexity gains a more direct mobile distribution channel for its assistant and research products, while competing browsers face added pressure to make AI assistance part of routine navigation rather than a separate destination.
- Publishers whose traffic comes through Comet must contend with the tension between AI-mediated browsing and ad blocking; Perplexity's earlier Comet Plus publisher-revenue initiative makes that tension central to its browser strategy.
Third-order effects
- If assistant-led browsers gain sustained usage across mobile platforms, the browser can become an agentic work surface that controls discovery, summarization and task execution—not merely a page viewer.
- The combination of AI answers and ad blocking could further push publisher-platform negotiations toward compensation and attribution models that do not depend solely on conventional display-ad impressions.
The trend: AI companies are turning assistants into cross-platform browser layers that mediate both user tasks and access to web content.
