Elvador is an artificial intelligence assistant designed for hotels. It manages guest communication across telephone, WhatsApp, and web channels around the clock. The system handles reservations, reception tasks, and guest service requests autonomously. It supports voice and text interactions in over 40 languages and aims to provide responses within an average of 1.2 seconds. Elvador claims a 100 percent response rate and an autonomous resolution rate above 85 percent. The tool can operate with full integration into a hotel's Property Management System (PMS) or independently. Main capabilities include voice reservations using natural human speech when the hotel phone line is busy or unanswered, a WhatsApp chatbot, mobile check-in with minimal physical contact, and dynamic upselling to increase revenue. Direct bookings through the system incur zero commission. All guest requests are routed to the appropriate department in the guest's preferred language without delay. Typical use cases involve reducing staff workload by automating routine inquiries, capturing reservations from missed calls, and improving guest satisfaction through instant multilingual support. The system also provides analytics and reporting capabilities. Technical requirements include integration with existing hotel software such as a PMS, although specific compatibility details are not listed on the website. Elvador is positioned as a tool to digitize hotel operations and enhance both guest experience and revenue. It is supported by various institutions and has references from businesses that have adopted the solution. The company offers a demo request option for interested hotels.
