Tripwire

Tripwire protects older people from phone scams while the call is still happening. The problem. In October 2026, a retired couple in Nebraska handed $158,000 in gold bars to a fake "federal agent's" courier at their front door. In Orlando, a caller pretending to be the bank asked a couple to read out the code their real bank had just texted them, and took $7,500. Americans over 60 lost $7.7 billion to fraud in 2025. Banks only see the money leave, and by then it's too late. What Tripwire does. Muse Voice Transcribe turns the call into text as it happens. Muse Spark Open reads each line (and, on a Windows computer, each screen) and notes the warning signs: who the caller claims to be, what they want, how close they are to the money. Muse Spark weighs the whole call and decides whether to stop it. When it does, Tripwire says on the call "Stop. This is a scam. Hang up the phone now," takes the person off the line, and puts a decoy played by Muse Wonder in their place to learn how the scammer planned to get paid. It stops the scams that work today: 1. "Read me the code we just texted you." The call ends the moment a caller asks for a one-time code. This is a fixed rule, so it acts instantly. 2. "Just tap merge" or "dial star seven two." Tripwire stops tricks that steal the code without the person ever saying it. Also a fixed rule. 3. "Grandma, it's me, I'm in jail." Tripwire asks the real grandchild on their own phone. One tap of "That's not me" ends the call, however real the cloned voice sounds. 4. A fake website that looks exactly right. Muse Spark Open reads which company the page claims to be. Tripwire compares that with the browser's real address, and catches clones even when the address and padlock look correct, for example an address where one letter is Cyrillic. 5. The same scam told by a new scammer. After every stopped scam, Muse Spark writes down the scammer's script and Muse Spark Open checks it. On later calls, Muse Spark Open recognises the same script in different words. 6. The family gets one text with what happened. It includes a picture of what the scam looked like, made by Muse Image from the real screen, with SAM 3.1 outlining the danger. Muse Spark writes the story in plain words, and Muse Wonder writes a case file for the police. Why it can be trusted. Tripwire can't act on a guess. Every reason Muse Spark gives for stopping a call must quote what was actually said. Muse Spark Open then checks each reason on its own before the call is stopped. Our own fine-tuned Llama 3.2 1B gives a second opinion. On calls we didn't write, Tripwire stopped 100% of 160 scam calls with no false alarms on 160 normal calls, and 95% of 20 real recorded scam calls.
