Many users already work with a dual setup: The browser runs in one tab with dozens of open pages, while an AI tool such as ChatGPT or Perplexity, which is supposed to explain or summarize content, runs in the other tab. This is exactly where AI browsers come in and integrate this assistance directly into the browser. The pages continue to load as normal, but an integrated AI „reads“ in parallel, helps to classify, summarize and compare information and - depending on the solution - can also support simple steps on the web. The spectrum ranges from classic browsers with an additional AI function to AI-first browsers such as Atlas or Comet, which were designed from the outset so that the AI level forms the core of use.
