How it works

Drei Sekunden.Full picture

Nudge läuft leise im Hintergrund.Wenn Sie auf einer Seite landen, funktioniert sie bereits.

01
You visit any website
Nudge instantly checks the domain against our 1.1 Million+ verified domain database and community signals from our network of users.
02
AI scores the page
For unknown sites, our AI analyzes the content, payment fields, seller signals, and scam patterns to generate a trust score from 0–100.
03
You see the verdict
A badge appears showing green (safe), amber (caution), or red (danger) — with a plain-English explanation and safe alternatives if needed.
What Nudge does

Der Schutz funktioniert tatsächlich.

Keine Blockliste, kein Filter, echte Intelligenz auf jeder Seite, in Echtzeit.

🛡️
Trust score on every page
Every site gets a score from 0–100. Established retailers, unknown sellers, marketplace listings — all scored with context-specific reasoning you can actually understand.
