The README opens with
Write the condition the way you would say it. Postgres does the rest.
jev lets you filter, rank and classify rows with plain-language conditions. Every row is judged by TypeSafe's Jev, a System One model that returns calibrated probabilities instead of generated text. No index, no embeddings, no vector column.
jev() is an ordinary boolean function, so it composes with everything else in SQL: AND age 40, joins, GROUP BY, LIMIT, ORDER BY jevprob(...).
