Hidden Text Detector by PSM Marketing

Hidden Text Detector scans any webpage for text that's been hidden using CSS tricks — and shows you exactly what's there and why it's hidden. Why hidden text matters: Websites sometimes hide text from human visitors while keeping it readable to search engines, scrapers, or AI tools. This can be innocent (leftover code, accessibility text) or deceptive (SEO keyword stuffing, cloaking, or hidden instructions aimed at AI browsing tools and chatbots). Either way, if you can't see it, you can't judge it — until now. What it detects: Hidden Text Detector checks every piece of text on the page against the most common hiding techniques: display:none / visibility:hidden Zero or near-zero opacity Zero or near-zero font size Text color that matches the background Content positioned off-screen Elements shrunk to zero size Clipped or clip-path-hidden regions How it works: Click the extension icon on any page Hit "Scan Page" Get a list of every hidden text snippet found, with the reason it's hidden Click any result to jump straight to it on the page Use "Highlight All" to visually outline every hidden element at once Who it's for: SEO professionals auditing sites for cloaking or spam techniques Developers debugging unexpected hidden content Security-conscious users checking for hidden prompt-injection text aimed at AI tools Anyone curious what a page isn't showing them Privacy: Hidden Text Detector runs entirely in your browser. It doesn't collect, store, or transmit any data — no analytics, no tracking, no external servers. It only reads the page you're actively viewing when you click "Scan."
