bunch of people in my network stopped going on LinkedIn. Same reason every time — too many AI posts. So I built a Chrome extension that lets you filter them out. Pre-AI scans your feed in real-time using 271 detection signals. One click and AI posts disappear. Click again and they come back. Three modes: Pre-AI (hides AI content), AI Only (shows nothing but), All (everything with subtle markers). 100% local. No data collected. No account needed. Free forever.
