Perplexity's new Comet browser for iPhone puts artificial intelligence at the center of web browsing, letting you ask questions about any webpage you're viewing without switching apps. The free iOS app, which arrived on March 18, 2026, represents a significant bet that AI shouldn't live in a separate search box but should be woven into the browser itself. What Makes Comet Different From Safari and Chrome? Comet isn't just another browser with AI features bolted on. It's built around Perplexity's answer engine, which means every interaction assumes you might want AI help. Open a new tab, and instead of a blank page or your favorite websites, you get an AI assistant panel ready to help. The browser includes several features designed specifically for mobile users. Voice mode lets you ask hands-free questions about whatever webpage you're reading, powered by OpenAI's real-time voice API. Deep Research, Perplexity's full research engine, is available on your phone, letting you pull information from multiple sources and get structured summaries with citations while you're on the couch. One reviewer who tested Comet for 48 hours found that cross-tab comparison actually works. When asked which of three open tabs had the best deal on a cast iron skillet, the AI correctly read across all three pages and provided an accurate comparison. For research and comparison shopping, this is genuinely faster than manually checking each site. Where Comet Falls Short Against Safari? Despite its AI strengths, Comet has significant usability problems that make daily use frustrating. Accessing bookmarks and favorites is buried in menus rather than one tap away like in Safari. The new tab page always opens the AI assistant panel with no option to customize it to a blank page or your frequently visited sites. This means you have to dismiss the assistant first before typing a URL you normally just tap. For simple searches, Comet shows only the top three results, compared to Safari's ten results plus maps, images, and knowledge panels. When you just want to quickly check the weather or find a nearby restaurant, Comet's answer engine feels like a step backward. Agentic features, which let the browser perform multi-step tasks like finding a restaurant and checking if it has outdoor seating, work about 70 percent of the time. The technology is impressive in demos, but in real-world use, it's not reliable enough to trust without verification. How to Choose Between Comet, Safari, and Other iOS Browsers - For AI-powered research: Comet wins decisively. If you do comparison shopping, deep research, or need to synthesize information across multiple tabs, Comet offers capabilities Safari simply cannot match. The Deep Research feature alone justifies trying it if research is part of your workflow. - For everyday casual browsing: Safari remains superior. It's faster, uses less battery, integrates with your Apple Keychain, and bookmark access is far more convenient. Links from other apps open automatically in Safari without friction. - For Google integration: Chrome on iOS offers better bookmark management and tab groups, though its AI features through Gemini are limited compared to Comet's agentic capabilities. All iOS browsers technically use Apple's WebKit engine under the hood, so they render pages identically. The real differences come down to interface design and features layered on top. Pricing and Availability Comet is free to download and use on iPhone, with optional Pro features available for $20 per month. The browser launched on desktop in July 2025 at $200 per month, came to Android in November 2025, and arrived on iOS in March 2026. An iPad version has not been released yet. Cross-device syncing works well across platforms. You can start a research thread on your Mac, pick it up on your iPhone during lunch, and the full context is there, with history, tabs, and bookmarks synced and encrypted with a private passphrase. The Bigger Picture: AI Search and Browser Evolution Comet's launch reflects a broader shift in how people expect to interact with information online. Rather than typing keywords into a search engine and scanning results, users increasingly want to ask questions and get direct answers. Perplexity's answer engine competes with ChatGPT's search features and Google's AI Overviews. The aggressive built-in ad blocker, enabled by default, makes pages load noticeably cleaner. You can whitelist specific sites if you want to support creators, but the default experience removes most advertising clutter. For marketers and content creators, Comet's rise matters because it represents a new distribution channel. Companies like BYAHT Inc., which develops influencer marketing software, are already preparing for this shift by adding Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO) features to ensure creator content is structured for indexing by AI search engines like Perplexity. The verdict: Comet is worth downloading if you do research or comparison shopping on your phone. For casual browsing and everyday comfort, Safari remains the better choice. The real question isn't whether Comet will replace Safari, but whether AI-native browsers will eventually become the default way people explore the web.
