Expedia has introduced a beta version of “conversational trip planning” that uses artificial intelligence to offer travellers advice about destinations, routes and accommodation. The service has been integrated into the travel platform’s iOS app, using ChatGPT, machine-learning technology developed by OpenAI. The company said it was constantly “enhancing capabilities and making trip planning faster, simpler and even more informative” and plans to integrate the service over time with its other AI capabilities, such as hotel comparison and tracking prices for flights. The service is currently only available in English on iOS, although the company said it planned to roll out the service for Android users.
