Sentinel is a multilingual AI shield that checks anything that feels like a scam (a live phone call, a voice note, a screenshot or a message) and tells people, in their own language, exactly what to do.

Scams like “digital arrest” calls, fake KYC messages and voice-cloned “relatives” work because victims are scared, rushed and alone. Sentinel sits on that call with them. During a live call, it separates the two speakers, identifies the likely scammer, and the moment the user is about to pay or share an OTP, it takes over the screen with a specific spoken warning. For screenshots, it marks exactly where the fraud is. For voice notes, it flags the scam and judges whether the voice sounds AI-cloned. For messages, an agent checks every link and number and searches for scam reports before answering. The whole app works in English and Hindi.

Built on Meta’s models: Muse Wonder as a tool-using investigating agent, Muse Spark 1.3 for real-time call analysis, Muse Voice Transcribe for live transcription with speaker separation, and SAM 3.1 for visual evidence. On a 65-case multilingual test set, including 30 deliberately hard cases, it flagged all 38 scams with zero false alarms. It’s live, with one-click demos.
