🔍 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
