KAYAK, the world’s leading travel search engine, today launched AI Mode, a natural-language search experience that combines KAYAK’s data with ChatGPT to deliver smarter, contextual results, right from the home page.

KAYAK is the first major travel site to let users plan complete trips by typing questions directly into a search box.

“We launched KAYAK.ai in April for our software engineers to test cutting-edge AI capabilities. AI Mode is the first feature to graduate to our main site,” said Steve Hafner, KAYAK CEO. “Travellers aren’t limited to preset entry fields anymore. Just tell us what you’re looking for in plain language, and we’ll answer the same way.”

  • Discover, compare, and book flights, hotels and cars—all in one place.
