About Bible Diff

What Is This?

Bible Diff is a free tool for comparing Bible translations side-by-side, word-by-word. Select any two translations from over 30 available versions and instantly see exactly where and how they differ.

Whether you're studying a particular passage, researching translation philosophy, or just curious how your favorite verse reads in different versions, Bible Diff makes the comparison easy and visual.

Why Build This?

Every Bible translation makes choices. Some prioritize word-for-word accuracy, others aim for thought-for-thought clarity, and still others balance readability with fidelity to the original texts.

These choices matter. A single word difference can shift the meaning of a verse. Bible Diff exists to make these differences visible so you can study Scripture with greater understanding of how translation decisions affect the text you're reading.
