Hyatt integrated a branded app within OpenAI's ChatGPT platform that lets travelers search Hyatt hotels worldwide using everyday conversational language, browse real-time room availability and rates, and then click through to Hyatt.com to complete a booking. The app was announced in February 2026 and is available inside ChatGPT to users in all markets where ChatGPT supports third-party apps.

The Hyatt app in ChatGPT, confirmed on OpenAI's official page, accepts natural-language prompts from ChatGPT users and returns Hyatt property results including room descriptions, dynamic rates, and availability pulled directly from Hyatt.com. Bookings are not completed inside ChatGPT; users are redirected to Hyatt's own platform to finalize reservations and earn World of Hyatt loyalty points. The app uses ChatGPT as a discovery channel, allowing Hyatt to reach travelers earlier in the trip-planning process and reduce reliance on third-party online travel agencies.
