System1 has launched Test Your Ad Screen, an AI tool that lets marketers evaluate up to 100 finished long-form advertising assets in minutes. The platform predicts creative effectiveness using 18 million human emotional responses, helping brands decide which ads warrant further investment before committing media budgets.
The tool builds on System1's Test Your Ad Competitive Edge platform, which holds millions of consumer responses to advertising. System1 says this dataset gives Test Your Ad Screen an empirical foundation, with predictions based on how people respond emotionally to advertising rather than synthetic data or assumptions.
How the screening works
Test Your Ad Screen reports results across low, medium and high ranges for key creative diagnostics rather than providing precise decimal scores. According to System1, this approach gives marketers a directional view of an asset's likely commercial impact against category and emotional norms.
The company says the tool's outputs match human testing nine times out of 10, and that it withholds results when it does not have sufficient confidence in its predictions. The screening tool forms the first stage of a two-step creative effectiveness process.
For creative teams managing large portfolios of assets, the tool provides a way to identify stronger candidates before allocating media spend or commissioning more detailed research. Assets that warrant deeper analysis can then go through Test Your Ad, System1's consumer research platform, which provides precise diagnostics and qualitative insights based on testing with real consumers.
Combining AI with human emotional data
Andrew Tindall, Chief Growth Officer, Advertising at System1: "Marketing teams today are faced with delivering an increasing number of creative assets. Test Your Ad Screen helps them make more decisions faster and more regularly, with accurate and predictive data in minutes. This enables brands to understand creative quality and make better informed decisions about where media spend should be allocated."
James Gregory, CEO of System1: "We believe the future of creative effectiveness lies in combining AI with real human understanding. Test Your Ad Screen is built on millions of real human emotional responses, not synthetic data or assumptions, helping marketers screen creative 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 emphasis on human emotional data is central to how the tool differentiates itself from AI options that rely purely on synthetic outputs or theoretical models. For professionals working in creative roles who see AI tools emerge each week, the ground truth comes from what the data is built on - in this case, millions of recorded human responses.
The platform is currently available in the US and UK for long-form advertising assets. System1 plans to expand the tool to additional markets and different channels.
Why this matters for creatives
For creative teams operating under tighter budgets and growing demands, the practical value is speed. The ability to screen dozens of assets and identify which ones merit human testing - and which ones the AI flags with confidence - can change how a team allocates effort. If you're working on a campaign with a tight deadline, the timescale of minutes rather than days or weeks means you can iterate on the creative or kill approaches before they drain resources. The limitation is equally important: this is a filtering system, not a decision machine. If the tool cannot confidently classify the asset, it tells you so, rather than making a guess.
For those working directly in creative roles, the rise of AI ad screening tools like this one poses a straightforward question: which part of the creative process is enhanced, and which is being decided for you? Results that come back as score ranges, with a stated alignment to human testing, point to a workflow where the AI is a first pass, but still rely on human judgment - and human viewers - for decisions that matter. That makes tools like this a partner in the creation process rather than a replacement, and one worth testing if you need stronger validation for your work.
Marketers and creatives looking to understand these tools in practice may find the AI for Marketing Managers learning resource useful, while those focused on the creative side can explore broader applications through the AI for Creatives tag page.
