System1 launches Test Your Ad Screen
New AI-enabled product expands System1's Test Your Ad platform
System1 www.system1group.com, the marketing decision-making platform, is pleased to announce the launch of Test Your Ad Screen, an AI screening tool providing rapid, directional predictions of an advertisement's commercial effectiveness.
This tool has been trained on 18 million real human emotional responses from System1's Test Your Ad Competitive Edge database, which the Company believes to be the world's largest database of human emotional norms. The new tool helps marketers screen up to 100 finished long-form adverts or other pieces of creative material ("creative assets" or "assets") at a time, with results available in approximately 10 minutes.
Results are presented in ranges across key diagnostics, giving a directional and honest read of where an asset's commercial impact is likely to land relative to category and emotional norms. Test Your Ad Screen's predictions match human testing nine times out of ten and the screening tool won't show a result if it lacks confidence in the accuracy of its predictions.
Test Your Ad Screen expands System1's existing product offering, providing a more affordable entry point for new customers and enabling existing clients to assess a greater volume of creative assets. The launch supports the Group's strategy of driving growth through product innovation, customer expansion and new customer acquisition.
James Gregory, CEO of System1 commented: "We believe the future of creative effectiveness lies in combining AI with real human understanding. Test Your Ad Screen is trained on millions of real human emotional responses, not synthetic data or assumptions, which we believe will help marketers screen creative assets quickly while staying grounded in how people actually feel. This is not a replacement for human testing, but a complement to it, and an important next step for System1 in bringing AI and human emotion together. The launch extends the breadth of our Test Your Ad platform, strengthening our offering to customers and supporting growth through continued product innovation."
