Perplexity today launched its Comet AI browser for iOS, offering its powerful assistant for free, a significant shift from its previously paid desktop version. The iOS app mirrors core Comet features like voice queries and hybrid search but lacks extensions. Crucially, the free Comet Assistant provides deeper answers and completes tasks like email summarization and price comparisons, leveraging Perplexity's Deep Research to synthesize information from multiple sources. This move makes advanced AI search capabilities accessible without cost, directly competing with paid alternatives.

While Comet for iOS is free, Perplexity still monetizes through Pro and Max subscription plans starting at $20/month for enhanced features. The app supports cross-device sync, allowing users to start searches on one device and continue on another. Perplexity collects browsing history to build ad-targeting profiles, a common practice in the AI space. The launch represents a strategic expansion for Perplexity, aiming to capture a broader user base by removing the initial $200/month paywall.

The free iOS version provides substantial functionality, potentially attracting users seeking AI-powered search without subscription costs. However, the long-term viability depends on balancing free user acquisition with revenue generation through premium tiers and targeted advertising. This development underscores a broader industry trend towards democratizing AI tools, even as companies seek sustainable monetization models.
