Savi's App Aims to Protect Consumers From Realistic AI Scams Like Fake Kidnapping Calls

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. 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."
