OpenAI announced ChatGPT Atlas — a browser that puts ChatGPT at the center of browsing. Perplexity already did this months ago with Comet. People noticed.

Atlas adds chat, memory, and agent mode to your browser. Talk to ChatGPT about any webpage. It remembers what you've browsed and suggests relevant content. Agents automate bookings and form-filling. Available for macOS now.

Perplexity launched Comet in July 2024 — nearly a year earlier. Same feature set: sidecar assistant, task automation, background agents. After launching at $200/month, they made it free globally in October 2025.

Both solve the same problem the same way, and neither is truly innovative since it is what you would expect when combining an LLM with a browser. OpenAI wins on distribution — 200+ million ChatGPT users. Perplexity gets credit for building it first and making it free.

What are these browsers actually for?

I have used Comet to find coupons, search things, and summarize pages, and it works fine. But what can an AI browser do that opening ChatGPT in a tab cannot?

Automated bookings sound appealing, but do you trust your browser with payment info? Managing Linear projects sounds good until you remember people already have integrations, and inline text editing only saves a single click.

People don't need an AI browser. They need Gmail with AI writing, Linear with AI summaries — apps that already have AI built in. The browser is a distribution channel, not the product.

Both assume the bottleneck is information access or task automation. It's judgment. I don't need AI to find the cheapest flight — I need to decide if the layover is worth it. I don't need AI to summarize an article — I need to know if it matters. These browsers automate what was already easy.

OpenAI wins on scale. Perplexity built it first and made it free. Both will find users, but neither will replace Chrome. When you have a great LLM, integrating it everywhere is the obvious next step, and that is not innovation but simply the market filling in the gaps.
