How it works

When you ask about tours, ChatGPT renders an interactive widget directly in the conversation — not just text. You can browse, explore details, and book without leaving the chat.

1. Discover tours in a city

"What can I do in Barcelona?"

ChatGPT shows an interactive carousel with tour cards. Each card displays the photo, rating, reviews, duration, and price. Scroll through to explore, then use either button: "See details" to view the full tour page, or "Availability" to jump straight to the calendar.

2. View tour details

Click "See details" on any card to open the tour in fullscreen mode — the chat disappears and the widget takes over. You get the photo gallery, guide info, itinerary with stops, reviews, meeting point, and what's included. This view is read-only for focused browsing. Use ChatGPT's native X button to close and return to the carousel.

3. Check availability and book

Click "Availability" on any carousel card to open the calendar directly in fullscreen mode — no need to go through the detail page first. Select dates to see available time slots. Each slot shows the language and a "Book now" button that opens the booking page on GuruWalk. Use ChatGPT's native X button to close and return to the carousel.
