Habla con la Palabra
A Catholic app to converse with the Bible: authentic, validated verses — never invented.
✦✦
“Return to your rest, my soul” · Ps 116:734,623 validated verses
The project
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.
What it does
- 34,623 verses with quantized embeddings (int8, ~36 MB).
- Anti-hallucination: every citation is validated against the literal text.
- Progressive streaming: the verse first, then the reflection.
- Mass near you: churches and schedules via Google Places.
