AI browsers. Supposedly, they’re the future of the web. The pitch goes like this: websites will stop being designed for humans and start being designed for AI agents instead, with clean structures, predictable buttons, and machine-readable intent. You won’t browse anymore. You’ll instruct. The agent will scan, click, compare, and decide on your behalf. That future may arrive eventually. Right now, we are nowhere near it.
Two of the most prominent attempts at this agentic browser idea are Perplexity’s Comet and OpenAI’s Atlas. Both promise to act on your behalf inside the browser. So we tested them side by side, using the same prompts, on the same sites, with the same constraints. Which one works best? The short answer: they are not the same. One of them consistently performs better, faster, and with fewer self-inflicted wounds.
