Hands-On With AI Browsers: Comet Leads Daily Use as Atlas, Zen and Dia Gather Interest

Early adopters cite faster workflows from AI-first browsing, with security trade-offs still top of mind.

Overview

  • An early user switched from Brave to Perplexity’s Comet as a primary browser, citing smooth, context-aware assistance that can summarize pages and reason across open tabs.
  • Comet’s integration keeps Perplexity’s assistant available throughout the interface, enabling highlight-to-ask actions and multi‑tab comparisons to speed routine tasks.
  • OpenAI’s ChatGPT Atlas, released in late October, is under evaluation by the tester, who finds it promising but not yet as mature for everyday work as Comet.
  • The piece notes growing interest in Zen Browser and Dia, describing Dia as a successor to Arc after that project stalled, as developers reposition for AI‑centric browsing.
  • Security research referenced by the author, including a Brave analysis, warns that indirect prompt injections hidden in images or page content can influence agent behavior and raise privacy concerns.
