Automated README summary
Automatically summarized from the README on 13 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A Chrome/Edge Manifest V3 extension for personal browsing that spots suspected spam, engagement bait, reposts, and ads on X/Twitter timelines, overlaying semi-transparent watermarks on post text. It is not a fact-checker or platform moderation tool.
How it uses Jev
The content script reads visible post text and metadata; the background service worker calls TypeSafe Jev directly. Jev answers two questions: whether the post is low-quality, and its main type. When low-quality probability reaches the threshold (default 75%), a red STOP watermark is shown in the tweetText container.
Primitives:choicescore
Technique worth stealing
Use Jev's probability plus content-type answer to drive a visual watermark, keeping the model call in the extension background.
Try it
Load the root folder containing manifest.json via chrome://extensions, set your Jev API key in the popup, then refresh X.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
