Because we do more. Multi-modal detection (text + images + video), publisher tools, and a Chrome extension. Others only do text. You're paying for the full origin intelligence stack.
Nobody else offers it. As AI-generated video explodes (Sora, Runway, etc.), platforms need to know what's synthetic. We're the only origin engine that covers video.
Shield Free gives you 50 text scans per day at zero cost. Install the Chrome extension and see origin intelligence in action before upgrading.
30-day money-back guarantee on all paid plans. If Verigin doesn't deliver value, we'll refund you. No questions.
