Up to half your ad budget lands on people who'll never convert. Clerk's Purchase Intent AI predicts which customers are likely to buy the products you choose, even ones they've never browsed, and pipes them straight into your ad platforms and email marketing.

Clerk's AI forecasts who's likely to buy any product you select — including customers who've never looked at anything similar. Define the target set the way that fits: free text, attribute filters like price > 100, or a list of product IDs.
