What is OpenAI Atlas
Atlas brings a persistent ChatGPT sidebar, inline writing help, and a new‑tab view that mixes chat with results for links, images, videos, and news where available. It offers an agent mode preview that can open tabs and complete steps with guardrails and clear limits for safety.
Atlas privacy and control
Memories are optional and can be turned off per site, and an incognito mode avoids saving chats and memory. The agent mode will pause on sensitive sites, cannot run local code or install extensions, and can even run while logged out for extra safety.
What is Google Chrome
Chrome launched in 2008 and became a cross‑platform standard with a vast extension ecosystem and strong performance. It remains the top browser across devices and use cases in 2025.
What is Perplexity Comet
Comet positions itself as an AI‑native browser that answers with citations, keeps context, and executes workflows in a natural flow. Media coverage notes staged rollout and availability details for desktop users, including in India for Pro subscribers.
Feature comparison
Who should pick which
Choose Atlas if you want built‑in help, optional memory, and guarded agents that act inside pages for research and planning. Choose Chrome if you need maximum compatibility, mature stability, and the largest extension and developer ecosystem. Choose Comet if you work in research and want cited answers and task flow inside a focused, AI‑first browser.
Chrome’s market and finance impact
Chrome holds about 71.77% worldwide market share as of September 2025, which keeps a strong funnel to Google services. Alphabet reported Q2 2025 revenue of about 96.4B USD, with about 54.1B USD from Search, showing the continued strength of search monetization that Chrome helps support. Chrome’s 2008 launch and long‑term growth shaped web usage at scale, reinforcing Google’s core ad and search business model over time.
