Policy changes rarely arrive as headline announcements. More often, they appear as small edits buried in lengthy documents: a revised definition, a rewritten clause, or language omitted from a later draft. Those revisions can alter what sanctions authorities permit, what agencies can enforce, and what the public can scrutinize.

PolicyDrift makes those changes easier to follow. It tracks primary-source legal text over time, preserves prior versions, and shows how documents evolve across revisions.
