Small businesses in Latin America get scammed through WhatsApp and have no
security team to ask. Almost half were phished last year.

VIGÍA is a WhatsApp number they forward anything to — a text, a voice note,
a screenshot, a PDF invoice, a flyer with a QR code — and get back a plain
verdict in seconds: scam, legitimate or unclear, why, and what to do. If it
is a scam, the whole team is warned at once, with the message quoted and the
link defanged. No app to install, no sign-up, no new tool to learn.

Deterministic country-pack signals run first and set the verdict; the model
can raise confidence but never revoke it. That is why, across three runs of
the same 231 cases, scam recall stayed at 98.5% and no real scam was ever
labelled legitimate — not once.

231 cases, 93.5% accuracy, 2.1% false alarms, $0.0038 per message. Every
run's raw results are committed in the repo.
