Hey, HN people - I’d pay good money for the opposite. My dad has fallen for two separate pig butcher scams. I’d love to install something on his phone to protect him, and an LLM could actually do that as long as it could integrate with whatsapp/messages/his email.

The latest one is ongoing and he doesn’t believe me, but if you could cut them off earlier before they’re hooked it would probably prevent it.

Hey - we started a company called Lifeguard to focus on exactly this! We focus on three parts: education (quick elearnings), finding/removing data (dark web scan, data broker removal), and auto-protection (chrome extension, iOS app, email integration - to label or block scam messages). I would love to talk to you to hear what product features would be most important for you. Please email me at kevin at trylifeguard.com

oh this is very cool!

I've been building in my spare time a spam/scam blocking extension and was also playing around with the experimental in-browser LLM feature for this (alongside Aho–Corasick, Naive Bayes and other classifiers)

It's great to see more people tackling this head on, kudos

I can't promise how effective it is but Google Pixel phones have a built in scam detection feature in their dialer app. It uses a local LLM that runs on device and analyzes the phone conversation. Here's their support doc: https://support.google.com/phoneapp/answer/15654065

It likely only works for US English phones, and of course if they get him onto other platforms like whatsapp or signal then it's no help. Sorry to hear you're dealing with that it's a big fear of mine as my parents age.
