Introduction to Comet

Perplexity has officially launched its AI-powered web browser, Comet, which is set on challenging Google Search's reign as the primary source of information online. This ambitious move from the startup comes after they have steadily introduced innovative products and services over recent months, positioning them as a strong contender in the web browser arena.

What is Comet?

Introduced on Wednesday, Comet is currently available to subscribers of Perplexity’s $200 monthly Max plan and a group of invitees from a waitlist. The browser's standout feature is the AI search engine, which is pre-installed as the default engine. This proactive approach effectively places Perplexity’s core offering—AI-generated summaries of search results—right where users can benefit from it the most.

Furthermore, users familiar with AI will appreciate Comet Assistant. This integrated AI agent resides directly within the browser, aiming to automate routine tasks and enhance productivity. Users can activate the assistant effortlessly while browsing by simply opening a sidecar window that allows it to interact with the content displayed on their current webpage. It’s designed to summarize emails, calendar events, manage open tabs, and even navigate webpages on behalf of users.

The Vision Behind Comet

Aravind Srinivas, Perplexity's CEO, has notably emphasized the significance of Comet in the company’s strategy to outpace Google. Srinivas mentioned a vision to create an operating system that enables users to conduct nearly all of their online activities without switching between various platforms. He believes that establishing Comet as the default browser could lead to unparalleled user retention and greater interaction with Perplexity’s offerings.

Perplexity has recently reported impressive user engagement metrics, processing around 780 million queries in May 2025, with their search products experiencing over 20% month-over-month growth. Yet, while entering the crowded browser arena, Comet faces formidable competition from the likes of Google Chrome and Apple’s Safari, which dominate the market.

Comet Assistant: A Double-Edged Sword

For many users, the most intriguing aspect of Comet may very well be the Comet Assistant. During testing, some users found it adept at handling simple tasks, yet its limitations became evident with more intricate requests, raising concerns over privacy. Users must grant access for the AI agent to function effectively, which can feel intrusive, as it requires the ability to access calendars, emails, and other personal information.

Using the Comet Assistant is convenient; it allows for queries to be made without switching windows or copying text. For instance, the assistant can review calendars and notify users about upcoming events. However, issues can arise when tasked with complex, multi-step processes.

Limitations and Challenges Faced

In one test, users attempted to find a long-term parking spot in San Francisco using Comet Assistant. Although it provided options that matched their criteria initially, it struggled to execute the booking correctly, indicating incorrect dates and repeating issues. Such experiences underline the persistent problem of AI agents generating inaccurate or irrelevant information—a challenge known as hallucination in AI.

This underscores a significant hurdle for Perplexity and others in the industry; until advancements minimize such errors, the efficacy of AI agents in completing complex tasks will be limited.

Conclusion

Despite the obstacles, Comet appears to bring fresh capabilities that have the potential to carve out a unique space for Perplexity in the browser market. While challenging established giants like Google is a monumental task, Perplexity's innovative approach with Comet reflects a commitment to rethinking how we access and interact with information online. By integrating robust AI features, Perplexity may indeed redefine user experience in web browsing.
