Habla con la Palabra
A Catholic app to converse with the Bible: authentic, validated verses — never invented.
Overview
Ask a personal or doctrinal question and receive an authentic Bible verse from the official BAC 2011 edition, plus a warm pastoral reflection. Behind it: 34,623 verses with vector embeddings, hybrid search (vector + Spanish BM25) and post-validation comparing every citation against the real text to rule out hallucinations.
