Predict the winner before you publish. Simulate 1,000 keyword impressions.
The AI simulates viewer psychology based on millions of viral video patterns. While it's a strong predictor of human behavior, actual performance depends on your specific audience and thumbnail.
This measures how likely a user is to click immediately without thinking (System 1 thinking). High impulse ratings correlate with viral explosions.
Use the 'Confidence Score' as a guide. If confidence is low (<60%), both titles are likely similar in quality. If high (>80%), trust the winner.
A/B testing is comparing two versions of something to see which performs better. In this case, we use AI to simulate how real viewers would react to your different title options.
Currently, this tool focuses on text. For thumbnail testing, we recommend using our Thumbnail Downloader to compare your design against competitors.
Our scoring is based on analysis of high-performing YouTube videos. While no tool can guarantee views, high-scoring titles generally follow the patterns of viral content.
