Mirai AI Infrastructure is a conversational and agentic architecture built natively on top of Mirai's direct-booking stack — not a chatbot added to the website. Its core is a reservation engine that has evolved to quote, book, modify and cancel inside a natural-language conversation, in text or voice and in up to 100 languages.

The architecture has five coordinated layers: the conversational booking engine; Knowledge, the hotel's canonical content database; Sarai, the conversational assistant that understands and responds to guests; Lobby, a control layer for monitoring, human hand-off, analytics and continuous improvement; and an MCP layer that exposes the hotel's content, availability and booking functions to external assistants such as ChatGPT, Gemini or Claude as that ecosystem matures.

Because every interface runs on the same inventory, pricing and rules, the guest gets one coherent experience across web, WhatsApp, voice and external agents. The same booking engine that answers a question about parking can close a same-day booking, without redirecting the user to a separate form. The AI runs autonomously in the large majority of cases; the hotel keeps full visibility and can step in whenever a conversation requires it.
