Is AI Marketer for LinkedIn safe on LinkedIn in 2026?

No — LinkedIn detects AI Marketer for LinkedIn (we checked it November 14, 2026). AI Marketer for LinkedIn's extension ID is on LinkedIn's AED detection list (Nov 2026 snapshot), and LinkedIn's page code checks for AI Marketer for LinkedIn on every visit by requesting chrome-extension://cnlpoekkkfjeibkpmlmbkgiliejlkaoc/helper.js — a file that exists only if AI Marketer for LinkedIn is installed. Our automated scan of AI Marketer for LinkedIn 1.1.1 found code that references LinkedIn's session cookie li_at (1 matches in 1 files); whether AI Marketer for LinkedIn sends that cookie anywhere needs a manual dataflow review.

Does LinkedIn detect AI Marketer for LinkedIn? What we found in its code

Detected by LinkedIn

This browser extension is actively compiled into LinkedIn's frontend detection lists. LinkedIn's scripts can detect when this is active on your browser.

LinkedIn requests: chrome-extension://cnlpoekkkfjeibkpmlmbkgiliejlkaoc/helper.js

DETECTED

What this means: detection isn't an instant ban — it's one input to LinkedIn's risk score. But it's a standing signal: it stacks with your behavior (volume, programmatic clicks) and device fingerprint, and this is just the AED list — one of LinkedIn's three detection systems (see how it works).

What our automated scan found in AI Marketer for LinkedIn's code

We downloaded AI Marketer for LinkedIn version 1.1.1 from the Chrome Web Store on November 2, 2026 and searched its 15 code files for the patterns below. Each line shows the first place we found it.

AI Marketer for LinkedIn's code references li_at — LinkedIn's session cookie, the one that keeps you logged in. 1 match in 1 file — first at background.js:6.
AI Marketer for LinkedIn uses the Chrome cookies API (chrome.cookies), which reads cookies of every site it has access to. 2 matches in 1 file — first at background.js:6.
AI Marketer for LinkedIn reads or writes document.cookie inside pages. 2 matches in 1 file — first at background.js:3.
AI Marketer for LinkedIn creates synthetic clicks or keystrokes (dispatchEvent / MouseEvent) — LinkedIn can tell these from real input (isTrusted=false). 5 matches in 3 files — first at client.js:41.
AI Marketer for LinkedIn makes its own network requests (fetch / XHR / WebSocket). 4 matches in 2 files — first at background.js:3.

What this scan is — and isn't. It is an automated static search of the shipped package, not a full teardown: a match means the pattern is in the code, not that AI Marketer for LinkedIn misuses it, and no match doesn't prove absence (minified or runtime-built code can hide it). We haven't traced where AI Marketer for LinkedIn sends data. How we test

How LinkedIn checks for AI Marketer for LinkedIn: the AED probe

That verdict isn't a guess. This is what LinkedIn's own page code does on every visit — simplified from its production bundle, which the BrowserGate investigation reverse-engineered line by line:

// LinkedIn's page bundle — simplified from BrowserGate's teardown

const hits = [];

for (const { id, file } of AED_LIST) // 4,934 ids incl. this one

try { await fetch("chrome-extension://" + id + "/" + file); hits.push(id); }

catch {} // not installed → silently swallowed

fireTrackingPayload("AedEvent", { browserExtensionIds: hits }); // → POST /li/track

// this extension is probed at:
// chrome-extension://cnlpoekkkfjeibkpmlmbkgiliejlkaoc/helper.js

How LinkedIn fingerprints your browser while you use AI Marketer for LinkedIn

Even after a cookie is copied out, LinkedIn keeps one more receipt on every request that follows — a 48-point snapshot of the exact machine making it. Faking it convincingly means reproducing that machine's quirks, not just editing a string.

Click any signal above for what it means. These are illustrative values — this demo never reads your actual device.

Your 48-point fingerprint — RSA-encrypted, attached to every API call in this session, not just login

This extension runs inside your real browser, so its requests always carry your real fingerprint — that isn't something it controls, it's simply where its code executes.
