Comet is an AI-powered web browser created by Perplexity, designed to blend artificial intelligence directly into the browsing experience. Unlike traditional browsers that rely on plug-ins or separate AI chat windows, Comet integrates an intelligent assistant throughout the interface. This assistant, called the Comet Assistant, stays aware of what’s on the screen and what the user is doing. When you highlight text or visit a website, Comet can instantly summarize information, explain complex ideas, or suggest follow-up questions — turning everyday browsing into an interactive, conversational experience.
If you’re fascinated by how tools like Comet are transforming everyday web experiences with AI, learning the broader context of artificial intelligence can deepen your understanding. AI For Everyone on Coursera, taught by Andrew Ng, offers a clear, non-technical introduction to how AI is reshaping industries, workflows, and human interaction — making it the perfect next step for anyone curious about the future of AI-driven technology*.
Built on Chromium, Comet supports standard web technologies and most Chrome extensions, but what sets it apart is how it treats AI as a natural part of web navigation. The assistant can draw from multiple open tabs, past context, and real-time web data to answer questions or perform tasks. Users can compare products, book travel, draft emails, or research topics without switching between apps. This creates a smooth workflow where the browser not only displays information but actively helps interpret and act on it.
Launched in July 2025, Comet initially rolled out to Perplexity’s premium subscribers before expanding to all users by October of the same year. It’s now available for free, with an optional Comet Plus tier offering enhanced features. Perplexity positions Comet as a step toward the “AI-native” internet — a vision where browsers evolve from passive tools into proactive research companions that understand intent and context.
However, the technology also introduces new challenges. Security experts have raised concerns about potential vulnerabilities, such as “prompt injection” attacks that could trick the AI into revealing data or executing unintended actions. Because Comet can access personal tools like email or calendars (if connected), these risks highlight the delicate balance between convenience and control in AI-driven software. Despite these issues, Comet represents one of the most ambitious attempts to redefine how people explore the web — aiming to make browsing more intelligent, responsive, and human-like in how it understands and supports users.
