What it is
A Chrome MV3 extension for X and LinkedIn users that scores every post for AI slop, showing a pill and blurring plus stamping posts above a user-set threshold, with a button to reveal them.
How it uses Jev
For each post scrolling into view, the extension sends the post text and author handle to Jev and asks one typed Choice (slop / not_slop). The returned probability drives the pill, blur and SLOP stamp at or above the user threshold; results are cached per post.
Primitives:choice
Technique worth stealing
One typed Choice per post with a per-post cache and a small concurrency cap, so scrolling is never blocked.
Try it
Load the chrome-mv3/ folder unpacked in chrome://extensions, paste your API key, then scroll X or LinkedIn.
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.
