What it is
A fun Chrome extension (Manifest V3) that detects ad-shaped DOM elements in real time and removes them. Intended for people curious about using a small decision model, not as a real ad blocker.
How it uses Jev
The content script collects ad-shaped candidates and describes each as a compact JSON object (tag, classes, label, text excerpt, link hosts, shape, IAB size). The service worker sends one noul question per candidate to systemone jev-latest; the returned probability per element drives removal at or above a threshold.
Primitives:noul
Technique worth stealing
Let code find candidates and build compact typed descriptions; send only the semantic question per element, one batch request.
Try it
Load unpacked in chrome://extensions, paste a TypeSafe API key in the popup, hit Test, browse.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
