M-Dash Detector

Overview

Highlights em-dashes (—) commonly used by AI models to make you aware of AI-generated text

Spot AI-generated text at a glance. M-Dash Detector highlights em-dashes (—) on any webpage—a typography pattern commonly favored by AI language models like ChatGPT, Claude, and Gemini. 🔍 HOW IT WORKS Em-dashes are one of several stylistic "tells" that AI models tend to overuse compared to human writers. While not every em-dash means AI, frequent use can be a helpful signal. This extension automatically scans webpages and highlights em-dashes with a subtle, eye-catching animation. ✨ FEATURES - Automatic Detection — Works instantly on every webpage you visit - Visual Highlighting — Em-dashes are marked with a distinctive sparkle effect - Count Badge — See at a glance how many em-dashes were found on a page - Lightweight — No impact on browsing performance - Privacy-First — Runs entirely in your browser, no data ever leaves your device 💡 PERFECT FOR - Educators and students verifying content authenticity - Journalists and researchers fact-checking sources - Content moderators reviewing submissions - Anyone curious about AI patterns in online text ⚙️ WORKS EVERYWHERE The extension runs automatically on all websites with no configuration needed. Just install and browse—the extension does the rest. 📖 OPEN SOURCE M-Dash Detector is free and open source. Check out the code, report bugs, or contribute on GitHub. Note: Em-dash usage alone does not definitively indicate AI-generated text. This tool is meant to raise awareness, not provide proof. Always use critical thinking when evaluating content.
