The AI-post filter that shows its work. NPC Filter is a free Chrome extension that spots likely AI-written posts on LinkedIn, X and Reddit and blurs, labels or hides them. Every flag names the signs it found, like "Not X, but Y" framing or stiff "serves as" phrasing, taken from Wikipedia editors' guide to spotting AI writing. Local rules run in your browser, free, with no account. Sign in for model checks on posts the rules miss. Only post text is ever checked. Reveal any post in one click.

Could you build this?
Yes A Chrome extension that scores posts with heuristic text-pattern rules (drawn from Wikipedia's AI-writing guide) and shows the matched signals is buildable with standard extension APIs and simple NLP. Accuracy will be limited but a working version is feasible.
