The Government Technology Agency of Singapore (GovTech) has launched an open beta of AntiScam Pango, an Android app that uses on-device artificial intelligence to warn people about suspicious conversations on WhatsApp, Telegram and SMS. Jasmin Lau, Singapore’s senior minister of state for digital development and information, unveiled the app at GovTech’s Stack 2026 conference, saying the agency is working with Google DeepMind on more advanced on-device AI models to make Pango smarter. The models are trained on real and synthetic Singapore scam messages, so they recognise the language and methods scammers employ in the local context. Google DeepMind and GovTech first disclosed their work on an on-device scam detection model at Singapore International Cyber Week in October, with Google’s lightweight Gemma model fine-tuned on local scam conversations. Once users grant permissions, the app operates in the background and looks at incoming message alerts, combining messages from the same sender into a conversation. A small classifier screens incoming messages, only passing suspicious ones to the Gemma model. In a sample alert, a WhatsApp chat demanding a S$200 registration fee is classified as a probable investment scam, with the user advised not to send money and to call 1799 if in doubt. The app does not block or delete messages, and all analysis is performed on the device.
