You are right that section could be much clearer.

Long term transaction data and browsing history could be used to train a federated learning algorithm to generate search results.

Getting access to that data to understand what stories it can tell is difficult ask without offering a lot of value in return.

In the short term I believe providing insights into a persons finances is the way to provide that value.

E.g. if you have an extra $5k how do your circumstances change if you - pay off student debt - pay extra on your mortgage - buy solar - contribute to your 401k / retirement savings

or showing how changes in spending alters the amount of pretax money you need to earn to support your lifestyle.

or how does your spending compare to people like you?
