Perplexity.ai has officially entered the browser market with the launch of Comet, its first standalone desktop browser that bypasses conventional search engines like Google and Bing. Instead, Comet is powered entirely by Perplexity’s own AI search engine, promising a more conversational and task-focused web experience.
Comet is set to launch for both Windows and macOS, but access is currently limited. The browser is technically free, but users must join a waitlist to download it—unless they subscribe to Perplexity Max, the company’s premium $200/month tier that includes access to advanced AI models and features.
Unlike traditional browsers that rely on third-party search engines, Comet leans on AI-generated responses and summaries to answer user queries. It can also perform additional AI-based functions, such as summarizing full webpages. While this AI-first approach distinguishes it from competitors, it shares the market with similar efforts like Dia, a new AI browser from The Browser Company of New York.
One aspect that may raise eyebrows is the extent of data access Comet requests. In order to act as a true assistant, the browser needs permission to access your calendar, email, and other private data. This opens the door to more personalized automation, but also raises concerns about user privacy and trust.
The browser also uses agentic AI, a model in which background agents handle tasks semi-autonomously, requiring user confirmation before finalizing actions. But early tests haven’t been smooth. According to TechCrunch reporter Maxwell Zeff, a test to book a parking space via Comet went awry. The AI entered the wrong dates, falsely claimed the user’s preferred time slots were unavailable, and attempted to proceed with checkout regardless.
While Perplexity’s vision is clear—AI-driven, context-aware browsing—Comet’s early hiccups suggest that there’s still work to be done before it can reliably serve as a full-time personal assistant.
