comet v atlas

The web browser landscape is experiencing a groundbreaking transformation. Conventional browsers are rapidly being replaced with intelligent “agentic browsers” – tools that actively assist with research, summarize web pages, automate tasks, and serve as always-available AI copilots. Two standout players in this revolution are Perplexity AI’s Comet Browser and OpenAI Atlas. In this blog, we’ll break down the real-life benefits, key features, and differences between these cutting-edge platforms to help you decide which browser fits your workflow best.​

What Makes Agentic Browsers Different?

Agentic browsers are a leap beyond Chrome or Safari. Instead of passively displaying websites, they transform browsing into an active, AI-driven experience:

  • They handle research and organize your findings.

  • They summarize emails, news, and entire web pages—instantly.

  • They automate repetitive tasks like filling in forms or booking meetings.

  • You get direct, conversational answers with cited sources, all inside your browser.​

Perplexity Comet: The Researcher’s AI Browser

Comet is tailored for power users who need to organize information, conduct deep research, or manage complex workflows. Here’s why professionals are making the switch:

  • Citations-first answers: Never rely on AI “guesswork”—Comet shows sources for every snippet of data.​

  • Spaces, Tabs, and Tools: Manage research, projects, travel, finance, and shopping all in one unified interface.​

  • Privacy: Comet includes strong ad and tracker blocking to keep your browsing secure.​

  • Assistant in Every Tab: Use built-in voice commands, automate repetitive actions, and even pull summaries from your Gmail—directly in the browser.

  • Free and easy to try: Generous free tier means no risk. Optional Max upgrade adds extra pro features.

OpenAI Atlas: Automation Engine for the Modern Web

Atlas, OpenAI’s browser, takes agentic browsing to the next level with robust automation and ChatGPT at its core:

  • Agent Mode: Automate multi-step research (from in-depth content gathering to web form filling), with the browser working on your behalf.​

  • Always-on ChatGPT: Every tab becomes a smart assistant, remembering previous tasks and adapting to your workflow.

  • Seamless Content Creation: Integrated writing, summarizing, and ideation tools for blogs, emails, and professional documents.

  • Cutting-edge browser memory: Atlas can pick up where you left off, making it great for large, complex projects.

One thing to note: Atlas is currently optimized for macOS, with Windows and mobile versions launching later in 2025.​
