Savi is a new mobile app that uses AI to detect deepfake voice scams, including fake kidnapping calls. It monitors calls in real-time for synthetic audio artifacts and alerts users before they are scammed.
A new app called Savi is tackling one of the most disturbing AI-powered threats on the rise: hyper-realistic deepfake voice calls, including fake kidnapping scams that terrorize families into paying ransoms.
The app runs in the background on a user's smartphone, actively monitoring incoming calls for signs of voice cloning and deepfake audio manipulation. When detected, Savi alerts the user before they fall victim to the scam.
Warning
FBI data shows that AI-powered voice scams increased over 300% in 2025, with average losses exceeding $11,000 per incident.
Savi uses a combination of acoustic analysis and behavioral AI models to identify subtle artifacts in synthetic speech that are imperceptible to the human ear. The app can flag calls that impersonate family members, law enforcement, or company representatives.
“We built Savi because the technology to clone someone's voice with just 30 seconds of audio already exists and is being weaponized against the most vulnerable people.”
