Currently answering from St. John Chrysostom (478 homilies), Saint Methodius of Olympus, Saint Dionysius the Great of Alexandria, and St. Athanasius the Great — more fathers are being added.
How it works. Your question is compared against thousands of passages from the fathers' writings using semantic similarity, computed entirely in your browser — your questions are never sent to a server. The best-matching passages are quoted verbatim and linked to the full reader. The first question downloads a small language model (~30 MB); afterwards everything is instant.
