How Golden Thread works
We search by meaning, not keywords. Ask a question, and we find the closest passages. No keyword matching. No AI answers. Just the actual sources.
Search by meaning, not just words
Golden Thread uses vector embeddings to understand what you mean, not just what you type. A search for "the body and blood of Christ" will find Eucharistic passages even if they don't contain those exact words.
This means rephrasing your query often finds different, sometimes better results. Try asking the same question in two ways and compare.
