Perplexity has officially made the move to web browsers, embedding its AI tools into Comet, its new Chromium browser.

Perplexity AI, the fast-rising search startup backed by Jeff Bezos, Nvidia and SoftBank, just launched its first web browser. Dubbed Comet, this AI-powered browser is designed to challenge Google Chrome ’s dominance, which still commands over 68% of the global browser market.

"While Chrome maintains its dominant share, these experiments indicate a strategic curiosity toward agent-led, context-aware alternatives that challenge the conventional search-to-click paradigm. This is no longer a browser contest,

The timing isn’t subtle. Perplexity recently unveiled Comet, an AI-first browser built to make search feel conversational and context-aware.

Firefox’s sidebar is one of many experimental methods that browser makers are using to find a new format for the AI era.

This is the second time this year that Microsoft Edge has become 40% faster. Microsoft Edge now features a significantly more responsive user interface. The browser now has a First Contentful Paint (FCP) below 300ms.

The company says it’s improved the responsiveness of several Edge features, including its settings page.
