System1 Group launches AI tool that predicts ad outcomes from emotion

August 28, 2026 · mediapost.com

System1 Group has released a self-service AI tool that scores an advertisement's likely performance from the emotional response it generates among viewers. The system pulls from millions of possible responses and hundreds of pieces of content to return a result in minutes, the company said. Pre-testing panels built on traditional methods can take days or weeks to produce comparable findings.

Creative testing that used to take a week now returns a read in minutes, giving planners a faster checkpoint before media dollars commit to a campaign. Agency teams evaluating multiple ad versions can screen each cut for emotional fit on their own schedule, running checks in-house as creative comes in. The tool adds another signal to the mix for planners who already weigh reach and frequency projections against creative performance, folding emotional response into decisions that used to rely on gut judgment or slower panel-based testing.
