Techniques for populating the fields of a form are disclosed. A machine learning model may be trained to predict associations between fields. The trained machine learning model may be applied to a plurality of forms to predict an association between a first field in a first form type and a second field in a second form type. Upon receiving a value for a first field in a first form of a first form type and based on the predicted association, the system may populate a second field of a second form of the second form type based on the value.
