What is APIS?
The AI Purchase Intelligence System (APIS) is a pre-registered research study measuring how frontier AI models respond to different content signals when making purchase recommendations. Using a forced-choice A/B methodology, we quantify the causal effect of 26 distinct content dimensions on AI preference.
This research provides empirical guidance for businesses optimizing content for AI-mediated commerce. As AI agents increasingly influence purchase decisions, understanding what makes content "machine likeable" becomes critical for digital success.
