What it does

Accuracy rose to 74.7% when the measured difference between headlines was decisive.

How you can use it

Start by drafting two different headlines for your next article, newsletter, or post. A developer can build a script using this benchmark's approach to compare the pair and predict which title readers prefer. To run the automated checks, they will need an access key that connects your program to TypeSafe.

Make sure your developer tests each headline pair twice by swapping which title appears first. The research shows the tool naturally leans toward whichever option is listed second, so averaging both runs removes that skew. Keep in mind that predictions can still be wrong and reflect historical reader habits rather than absolute rules.
