Reference Weight Premium
Genesis 1:1 and John 1:1 open with the same words — on purpose. Tap any cross-reference and see how two passages actually connect: shared language, prophecy, theme — each thread weighted, with matching color on the very words that carry it.

Illustrative preview — in the app every weight cites its evidence.
Interpretive Weight Premium
Literal, poetic, symbolic, moral, prophetic — every passage carries its senses in different measure. See them weighed and color-lit word by word. Then turn the lens: ten traditions, from the Ante-Nicene fathers to the Reformation, each rereading the same text.
