The AI-powered browser battle is escalating, and Perplexity AI has just fired a major shot with the launch of its revolutionary browser, Comet. Positioned as a direct challenger to Google Chrome, Comet introduces a futuristic browsing experience powered by artificial intelligence. As OpenAI also prepares to unveil its own AI-first browser, Chrome’s long-held dominance is facing its most serious threats yet.
Currently available by invitation to Perplexity Max ($200/month) subscribers, Comet is built on the Chromium framework and runs on both Windows and macOS. With seamless support for Chrome extensions, bookmarks, and settings, the switch from Chrome to Comet is practically frictionless—something that many users, including early testers, say removes a significant barrier to browser migration.
AI Assistant That Does More Than Search
What sets Comet apart is its built-in AI Assistant, an intelligent sidebar that allows users to interact directly with the content on any web page. From summarising articles and comparing products to booking appointments, sending emails, and even making purchases—this assistant turns browsing into doing. By understanding content contextually and enabling multi-step automation through conversation, Comet pushes the web from traditional navigation into intelligent task execution.
According to Aravind Srinivas, CEO of Perplexity AI, the idea for Comet was born after Chrome declined their request to include Perplexity as a default search engine. "They refused. Hence, we decided to build the Perplexity Comet browser," Srinivas wrote on X.
Built for Privacy, Personalization, and Performance
Comet’s privacy-first approach is another major selling point. It stores user data locally and explicitly avoids feeding personal information into model training. The browser also features a native ad blocker, and its personalized search leverages local history—without sending that data back to Perplexity servers. These features are tailored for privacy-conscious users and those demanding a cleaner, faster web experience.
What Industry Experts Are Saying
Tech leaders and investors are already praising Comet. Aman Kabeer of FirstMark called it “a masterpiece of a release,” highlighting how it simplifies the complex process of switching browsers with one-click Chrome import. Dharmesh Shah, CTO of HubSpot, said it felt like “living in the future,” comparing the integrated AI assistant to a full-time digital aide capable of acting across tabs and platforms. He added, "It can pretty much do anything that you could do inside the browser."
Matthew Berman, CEO of Forward Future, coined the term “vibe browsing” to describe Comet’s paradigm shift—where users instruct agents to act on their behalf rather than engaging directly with websites.
Even Garry Tan, CEO of Y Combinator, gave a public nod: “Comet is impressive. Great work, Aravind Srinivas.”
Competition Heats Up: OpenAI Browser Launch Incoming
Perplexity isn’t alone in this AI browser revolution. OpenAI is reportedly weeks away from launching its own browser, also based on Chromium and deeply integrated with its AI agent, Operator. With over 500 million ChatGPT weekly users and 3 million business subscribers, OpenAI's entry could redefine how we search and interact with the web.
Reports suggest OpenAI’s browser will focus on chat-based interfaces to reduce reliance on traditional navigation while offering deep personalization and persistent memory. Last year, OpenAI hired former Google Chrome VPs, signaling serious intent to challenge the status quo.
Will AI Browsers Make Chrome Obsolete?
Experts believe AI-native features—not just speed or security—will shape the future of web browsing. According to Sanchit Vir Gogoi, CEO of Greyhound Research, Chrome’s tab-heavy model is increasingly outdated in a world shifting toward conversational agents. While Chrome still enjoys 68% global browser market share with over 3.45 billion users, Gogoi warns this dominance is rooted in “legacy distribution,” not innovation.
He added that 51% of enterprise tech leaders believe Perplexity and OpenAI are launching browsers to secure first-party data access, tighten user feedback loops, and control the digital front door.
As Gogoi puts it, “The decisive factor in the AI browser market will be how effectively the assistant learns and adapts.” While Perplexity bets on a local-first approach, OpenAI is investing in cloud-powered intelligence—two very different strategies with one common goal: to change how we browse forever.
