Perplexity has launched Comet, an AI-powered browser that can autonomously complete web-based tasks on behalf of users, representing a significant challenge to Google Chrome’s market dominance.

Currently available only to Perplexity Max subscribers or through an early access waitlist, Comet integrates artificial intelligence into virtually every browsing function to simplify web navigation and task completion.

The browser replaces traditional Google Search results with Perplexity’s AI “answer engine,” which appears when users type queries into the address bar.

Unlike conventional search engines that display comprehensive website listings, Perplexity first surfaces relevant links before generating synthesised information about the search topic, creating a more curated but potentially limiting browsing experience.

Comet features a built-in AI assistant accessible through a sidebar interface, similar to Google’s experimental Gemini integration in Chrome.

The assistant can summarise articles, describe images, analyse YouTube videos, scan multiple open tabs for comparisons, and conduct research on topics of interest.

Voice interaction capabilities extend the assistant’s accessibility and functionality.

The browser’s standout feature is its ability to perform autonomous tasks after users link their accounts to various services.

Testing revealed Comet’s capacity to compose and send emails, manage tab organisation, publish social media posts, process unsubscribe requests, and handle LinkedIn connection requests.

The browser visually demonstrates its decision-making process, showing what it “sees” as it navigates through complex task sequences.

However, performance comparisons suggest limitations in efficiency gains.

Unsubscribing from promotional emails took Comet approximately two minutes versus 30 seconds for manual completion, while LinkedIn invitation management also consumed more time than direct user interaction.

These delays may position Comet as more suitable for accessibility assistance or background task completion rather than speed optimisation.

Advanced agentic features activate when users begin prompts with “take control of my browser,” enabling more complex autonomous operations.

This functionality allows Comet to manipulate webpage elements directly, such as expanding comment sections, adding items to shopping carts, and completing checkout processes.

Testing demonstrated successful Amazon purchases, including product selection, shipping preferences, payment processing, and order completion.

Restaurant reservation attempts revealed current limitations, with Comet successfully navigating booking interfaces but using placeholder information for contact details instead of requesting actual user data.

These execution gaps highlight the technology’s developmental nature and potential failure rates for complex operations.

“Some of the more complicated agentic actions like shopping do have a higher failure rate than simpler tasks, but this is actually a limitation of current AI models,” explained Perplexity spokesperson Jesse Dwyer.

“So this will only get easier and better in Comet.”

The browser launch represents Perplexity CEO Aravind Srinivas’s broader strategy to challenge Google’s search and browsing dominance through AI-first experiences.

Comet’s capabilities exceed Chrome’s current Gemini integration, offering autonomous task execution that Google has publicly indicated interest in developing.

Industry observers note that Comet addresses growing demand for AI-powered productivity tools while highlighting the potential transformation of web browsing from passive consumption to active AI collaboration.

The browser’s success could influence how major technology companies approach AI integration in fundamental computing experiences.

The timing coincides with increased competition in AI-powered browsing tools, as companies seek to capture market share in what may become the next generation of web interaction paradigms.

Comet’s early release provides Perplexity with potential first-mover advantages in autonomous web task completion.

Privacy and security implications remain significant considerations as browsers gain deeper access to user accounts and autonomous transaction capabilities.

The extent of permissions required for full functionality raises questions about user control and data protection in AI-mediated web experiences.

For Google, Comet represents both validation of AI-powered browsing concepts and competitive pressure to accelerate similar feature development in Chrome, potentially reshaping the fundamental nature of web browsing as AI capabilities continue advancing.
