Which parts work without a paid model key?

Keywords match locally with no key and no traffic; smart labels call the official judging endpoint from your browser with your key and bill to your own account.

How much judging traffic will heavy scrolling generate?

Each fresh item costs one call of roughly a thousand-plus input tokens with local caching against repeats; keyword-only mode sends nothing at all.

What post data leaves the browser when smart labels run?

Post text, author names, topics, quotes, and already-visible comments go to the judging endpoint only; images, accounts, history, and settings stay local.

How do I tune what gets flagged versus merely labeled?

Sensitivity presets move the ad and topic cutoffs, custom categories accept name-plus-description pairs, and display toggles between inline labels and collapsing.

Which sites does ad-radar support?

Xiaohongshu, Weibo, X, and Zhihu, with labels placed differently on each site and matching content collapsed to one line or a covered card. The selectors live at the top of extension/content.js, so a site redesign is fixed there.

What are the sensitivity thresholds it uses?

Low, Medium, and High set different cutoffs: ad probability 0.8, 0.6, or 0.4, and topic probability 0.9, 0.8, or 0.7. All selected categories are judged together in the same request.

How much does judging cost?

One Jev call (jev-latest) per new item, about 1,200 to 1,700 input tokens, billed directly to your own Jev account. A local cache means the same item is never called twice, so judging ten thousand items costs roughly a few RMB, and direct access from mainland China may need a proxy.

Watch out

Recognition results are model estimates and can be wrong, and mainland direct connectivity to the judging API may need a proxy. Copy reviewed against the repository README on 2026-10-04, not from running it.
