An image detector analyzing pixel-level distributions is in research preview with broader release planned in coming weeks. Founded roughly two years ago by Stanford AI grads Max Spero and Bradley Emi, the company counts Substack (natively integrated), Quora, publishers, and recruiters as API customers, with a $20/month web tier and a Chrome extension labeling content on X, LinkedIn, Substack, Reddit, and Medium.
