Real-time scam detection
Scam calls stopped before your family picks up
Savi Security listens for the patterns that give away phone and text scams, and warns you before money moves.
Why We Built This
A phone call changed our family
"A fake IRS agent almost wiped out my grandfather's savings. The voice was calm, official, convincing. He nearly complied. That call is the reason Savi Security exists."
Phone and text scams cost Americans billions every year, and older adults are targeted disproportionately, often by callers who spend several minutes building trust before asking for anything. Caller ID is not enough. Most people recognize a scam only after the money is gone. Savi was built to warn before that moment arrives.
How It Works
Savi runs quietly. You do not change how you answer calls.
No new habits, no second app to check. Savi watches every incoming call in the background and speaks up only when something matches a known fraud pattern.

Savi listens for the tells
During every incoming call, our on-device model checks voice patterns, caller behavior, and message content against known fraud signatures, including AI-generated voice clones.
You get a warning before money moves
If something matches a known fraud pattern, you see an alert on-screen in real time. Hang up or stay informed. Either way, you decide with full information instead of finding out too late.
Detection Coverage
The scams people fall for. The signals Savi spots.
Our internal pattern catalog covers six major fraud categories active on US phone networks right now.
AI voice cloning
Synthetic voices crafted to sound like a family member in distress asking for emergency funds. Savi checks for acoustic artifacts that voice-generation tools introduce at the signal level.
IRS and government impersonation
Scripts that mimic official agencies, demand immediate payment, and threaten arrest. Savi flags the scripted pressure patterns that real government agencies do not use.
Medicare and insurance fraud
Callers posing as benefit providers asking to confirm your Medicare number or banking information. Any unsolicited request for those details by phone is a scam.
Gift card payment pressure
Any call that insists payment by gift card is a required step belongs to no legitimate business. Savi recognizes the urgency framing and gift-card demand pattern every time.
SMS phishing links
Text messages with fake shipping, bank, or government links designed to capture credentials. Savi checks message patterns locally before you tap anything.
Romance and relationship grooming
Extended phone contact patterns that build trust over weeks before introducing financial requests. Savi flags the behavioral signatures that distinguish grooming calls from normal conversation.
From our early-access program
From people who tried it first
I nearly fell for a Medicare call last spring. Savi flagged it before I picked up. My daughter sleeps easier now.
Helen R., Tucson, early-access program participant
Set it up on my dad's phone in ten minutes. He does not even know it is running. It stopped three scam calls last month.
Marcus T., Charlotte, pilot program participant
The text warnings are the part that surprised me. I was about to tap a shipping link and Savi stopped me cold.
