x-scanner

What it is

Behavioral labels on every post you scroll past on X, judged by Jev, TypeSafe's System One model, with a counter in the corner showing exactly what it cost.

Getting started

From the README:

git clone https://github.com/oso95/x-scanner.git
cd x-scanner
npm install
npm run build

Where the decision sits

x-scanner calls the hosted decision API rather than running its own weights. That keeps the project small and means its behaviour moves whenever the vendor ships a new model version. It also means an API key and a network round trip sit in the path of every decision.

Models it references: Jev.

How active it is
