Editor's Verdict
Editor's VerdictIf you care most about having an assistant that can actually take actions for you, like navigating the web, interacting with your tabs, reading your email, or pulling up your calendar, Comet Browser is the clear pick. Its agentic browsing lets you delegate real tasks to the built-in Perplexity Assistant, and it's the only browser right now that gives you this agent mode for free. For deep research or shopping where you want the assistant to find facts, cite sources, or even hunt for promo codes while you browse on mobile, Comet stands out.
Arc Browser, on the other hand, is all about productivity and organization. If your priority is tab management, switching between spaces, and customizing your workflow (and you love productivity tools like Motion or Notion), Arc is way ahead. It's built for people who live in their browser all day and want everything organized and snappy. But Arc doesn't offer the kind of agent-driven automation or web navigation that Comet does.
If you want your browser to actively do things for you, pick Comet. If you want a highly organized, productivity-focused browser experience, especially on MacOS, Arc is the better fit. For hands-off automation and research, Comet wins. For power user workflow and organization, Arc is the one.
