Savi listens for the tells
During every incoming call, Savi's on-device model checks voice patterns, caller behavior, and scripted-pressure signals against our catalog of known fraud signatures, including AI voice clones. Analysis happens entirely on the device. Audio is never uploaded.
You get a warning before money moves
If something matches a fraud pattern, you see a clear on-screen alert in real time. Hang up or answer with full awareness. Either way, you decide with information instead of finding out afterward.
Review your activity log
After each screened call, Savi logs which pattern triggered an alert and why. You can review, dismiss, or delete entries any time from the app settings. Your log is stored on your device only.
