## What is Vox Petri?

Vox Petri brings 145 years of papal encyclicals to your fingertips. Read the complete texts of 221 encyclicals from Leo XIII through Leo XIV, explore thematic connections across centuries of Church teaching, and visualize the web of citations linking documents together.

Features include a full-text reader with paragraph-level bookmarks, 20 thematic threads tracing ideas like Human Dignity, Social Justice, and Faith & Reason across the tradition, and an interactive connection graph showing how encyclicals cite and build on each other.   

Future releases may include full text search and the ability to get answers to questions via large language model integrations to the encyclical corpus.
