LinkedIn AI Slop

sciema.app / LinkedIn AI Slop

LinkedIn only · Chrome, Brave, Edge, Firefox, and Safari

A LinkedIn AI detector on the post card.

A badge while you scroll the feed: Human, Mixed, or AI slop. Hover a scored badge to see “AI slop: N%”. Scoring goes through TypeSafe Jev. The API key never enters the extension. Labels on the badge stay Polish: Ludzki, Mieszany, AI slop.

Install from GitHub Buy Pro, about 5 USD/mo The other extension: Sciema

The hosted proxy is a public demo with limits. For daily use, run your own proxy and your own key (BYOK). The Chrome Web Store is not the install path yet. The same zip runs in Chrome, Brave, and Edge. Firefox is a separate XPI (temporary add-on, no AMO listing). Safari is a Mac build, with no App Store listing.

What it does

1. Visible post

When a card is about 35% in view, the extension reads that post. Comments are skipped. Text shorter than 40 characters never leaves the browser.

2. Jev on the proxy

One call per post: model jev-latest, questions is_ai_slop, slop_intensity, has_substance, voice. The default threshold is 0.65.

3. Badge and percent

The color is decided in the repository. Hover the badge to see the probabilities, including “AI slop: N%”.

4. Banner with Pokaż

An AI slop verdict covers the card with a full-width banner: “AI slop” and a Pokaż button. After you reveal the post, the button becomes Ukryj. “Cover AI slop posts” is on by default.

The threshold slider

The model scores each post from 0 to 1. The „AI slop” badge appears when the score is at or above your threshold. The slider runs from about 0.15 to 0.95. The default sits around 0.65.

Lower, more sensitive

A threshold of 0.15 catches a weaker signal. More cards get the „AI slop” badge.

Higher, stricter

A threshold of 0.95 lets through only a strong signal. You see fewer „AI slop” badges and more „Ludzki” or „Mieszany”.

Privacy, short version

The proxy receives the post id, the text (up to 6000 characters), and optionally the name on the card. It does not write post text to disk. The extension stores the toggle, the threshold, the mode, the proxy URL, and an optional Pro token. The TypeSafe key is not stored there.

The full policy and terms stay on the GitHub Pages site: privacy, terms, demo.

Questions

Is this in the Chrome Web Store?

No. Load the unpacked extension/ folder. The same package runs in Brave and Edge.

How much is Pro?

Hosted Pro: about 5 USD per month or about 40 USD per year. Lifetime Pro: 199 PLN, one time. Team: 990 PLN per year for 10 tokens. BYOK and Hosted Demo are 0 USD.

What do I get after paying?

A Pro token. Paste it in the extension options. It is not the TypeSafe key. Demo has lower daily caps. Pro is for heavier use.

Is Safari on the App Store?

No. It is a Mac build from Xcode, with no App Store and no TestFlight. Nothing has been sent to App Store Connect.

Does it work outside LinkedIn?

No. It is for LinkedIn only. For scam labels and suspicious claims on ordinary pages, see Sciema.
