Perplexity AI, supported by high‑profile investors including Nvidia, Jeff Bezos, and SoftBank, has officially launched Comet, a new web browser built on Chromium to directly rival Google Chrome.

Comet integrates an agentic AI assistant—the Comet Assistant—that is embedded as a sidebar across web pages, enabling users to ask questions, perform research, compare products, summarize articles, and automate tasks like booking meetings or sending emails—all without switching tabs. Unlike traditional browsers that treat AI as an add‑on, Comet embeds intelligence into the browsing flow, reducing cognitive load and turning navigation into dialogue.

Comet is currently available exclusively to subscribers of the Perplexity Max plan, priced at $200 per month, with broader access planned via invite rollout over the summer of 2025. Initially supported on Windows and macOS, mobile compatibility (Android and iOS) is expected later in the year.

Privacy is a major draw, Comet stores data locally and does not train its AI models on user personal information, appealing to privacy‑conscious users. The launch marks a pivotal moment in the emerging AI‑browser wars, with OpenAI also preparing a competing AI‑powered browser, signaling a broader shift in how users access and interact with online information.
