Set Sail AI (setsailsoftware.com) promotes and deploys “digital human” solutions under its AI Kiosk/Virtual Service Ambassador line, featuring MTR’s AI Tracy—first seen at Quarry Bay Station and expanded to Kai Tak Station on February 29, 2024—as a hyper-realistic, always-on customer service avatar. Public posts also show use in events and education (including a 3D kiosk adopted by Hong Kong Police), contributions to StationCityline’s AI voicebot, and a collaboration with Singapore partner Trinax that showcases a digital human named AI Yannis. Across LinkedIn, YouTube, Instagram, and Facebook, the company invites inquiries and points to its platforms chatbot.com.hk and chatalog.ai for omnichannel deployment.
