What Makes Comet Different?

Comet isn’t your average browser—it’s built around agentic AI. This means it can execute user commands, summarise web content, handle form-filling, manage meetings, and even conduct deep-dive research automatically. The browser’s core lies in Perplexity’s ‘answer engine,’ fueled by models such as OpenAI’s GPT-4o and Anthropic’s Claude 4.0 Sonnet, as well as Perplexity’s own Sonar LLM.

No Blue Links: Instead of a pile of links, Comet offers concise, AI-generated answers right in your browsing window.
Built-In Assistant: Summon the sidebar for instant chat, context-driven queries, or even voice commands.
Chromium Powered: Enjoy standard browser features—tabs, extensions, bookmarks—but with an AI twist.

Is the Reign of Google's Browser Over?

The Reign of Google's Browser Over

For years, Google Chrome has been the undisputed king of web browsers, holding a massive global market share of over 64% in 2025. Its speed, extensive library of extensions, and deep integration into the Google ecosystem have made it the default choice for billions. However, Perplexity's Comet is not just another competitor; it's an entirely different kind of tool built on an “AI-first” foundation, aiming to change not just how we browse, but why.

The core difference lies in their fundamental approach. Chrome is a tool for accessing and displaying information, with AI features like Gemini being added on. Comet is an agentic AI browser, designed to be a proactive partner that understands context, automates tasks, and delivers direct answers instead of just links.

Is Comet Truly a Game-Changer in AI Browsing?

Comet’s universal AI assistant, agentic workflows, and focus on cutting digital clutter make it much more than a browser plug-in. It feels like an early glimpse at the future where the browser becomes a proactive partner, not just a passive tool.

For now, Perplexity still faces hurdles: price, rollout limits, and convincing mainstream users to switch from Chrome. But the early signs point to Comet becoming the browser benchmark that Google—and every AI-minded competitor—will need to chase.
