Abstract: Techniques for artificial intelligence (AI) custom fields are described. A method comprises receiving a custom rule comprising a query request for information in an electronic document stored in a data repository, generating a vectorized rule from the custom rule, selecting a subset of vectorized portions from a set of vectorized portions of the electronic document stored in a vector database corresponding to the vectorized rule, sending the vectorized rule and the subset of vectorized portions to a machine learning (ML) model, receiving a query response to the query request from the ML model, the query response comprising a summary of information contained within one or more vectorized portions of the subset of vectorized portions or a comment on the information contained within the one or more vectorized portions. Other embodiments are described and claimed.
