How it works

三分鐘,全景。

Nudge 在背景中悄悄运行. 您登陆页面的那一刻,它已经起作用。

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

保护确实起作用。

不是一个封面列表,不是一个过滤器,在每个页面上实时提供真实的信息。

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.

Marketplaces like eBay and Facebook show individual seller reputation. Retailers like Walmart show once per session, silently verified.
