Ever tried searching for a Bible verse you half-remember — not the exact words, but the meaning? Bible Vector Search lets you find Scripture passages by concept rather than keyword, using AI embedding technology to match your intent with the right verses.^1
Built on a vector database and AI embeddings, this free and open-source tool (MIT license) indexes the Bible in Basic English (BBE) translation and returns the most semantically similar passages to whatever you search for. Type a phrase like "God's unconditional love" or "overcoming fear" and it surfaces relevant verses ranked by meaning — not just word matching.^2 A live REST API lets developers plug semantic Bible search directly into their own apps and projects.^3
Bible Vector Search is part of the Antioch Tech project family, created by developer Tim — the same builder behind the widely used Obsidian Bible Reference plugin.^4 The Antioch Tech mission is rooted in 1 Peter 4:10: "Each of you should use whatever gift you have received to serve others."^4 Tim conceived the idea of applying vector search to Scripture a year before bringing it to life in mid-2024, noting that "vectorisation would be very suitable for Bible verse searching" — a gap he saw in the market at the time.^5
