What is grounding in AI?

Giving a model real source text to answer from, such as Bible passages or church documents, instead of relying on memory alone.

A free tool from Lumin, the Bible AI that cites every verse.Get the app

Also called retrieval-augmented generation, RAG

Why it matters for Christians

Grounded answers invent less. They can still misread the source, so the source should be visible.

What to do

Prefer tools that show the verse beside the answer, so you can see what it was grounded in. If a tool cannot show its source, treat its answer as a starting point, not a citation.

Ask about this word

Ask how it applies to you.

Lumin answers in a few sentences and names the passages it rests on. Each verse it cites is checked and shown in full below the answer, so you can read it yourself.
