Price comparers search flights and hotels for free, and no UK-confirmed AI assistant was found.
Kenning's take
What it does
A travel search engine that compares flights, hotels and car hire across hundreds of sites, then hands travellers to the provider to book. The app adds price alerts, a budget-based Explore map, a flight tracker, offline trip itineraries and a camera tool that checks whether hand luggage fits. KAYAK also runs a separate chat-based test site, KAYAK.ai.
