What it is
A Chrome/Chromium and Firefox extension that classifies nonessential page elements as clutter and hides them, storing reusable hiding rules per page template for the user.
How it uses Jev
Jev receives typed keep/ad/promotion/newsletter/social/cookie/uncertain choices over up to 60 bounded candidate element descriptions (tag, structural signals, short text, position, match count). Its probabilities decide which elements are hidden; selected-choice probability and TypeSafe confidence must both be at least 0.9.
Primitives:choice
Technique worth stealing
Template keys combine origin, policy version, page kind, normalized route family, and a stable main-shell marker, so rules are reused across similar pages.
Try it
Clone the repo, run bun install --frozen-lockfile and bun run build, then load .output/chrome-mv3 unpacked.
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.
