HAL AI Detector
Know when what you are looking at was made by a machine.
A cross-browser extension for Chrome, Firefox, and Safari. It reads the explicit AI labels the platforms ship — YouTube’s “How this was made,” X’s “Made with AI,” Instagram and Facebook’s AI-content pills, TikTok’s synthetic-media notices — and flags the sites whose output is AI by definition. Where the label is absent, as on X where disclosure is voluntary, it runs a fully local neural analysis on post images: a frozen ONNX backbone scores AI-versus-camera, and the verdict never leaves your device. Flagged images take a red AI watermark. The eye in the toolbar turns red.
