Short answer

How can I compare different versions of a statute using AI?

Your AI uses OpenLaws to pull specific historical versions of a federal law and generate a redline comparison between them. This shows you exactly what text was added, removed, or modified. You'll get a clear view of the legislative evolution through the following breakdown.

The outcomes

What you get from the comparison

The AI processes the raw statute data into actionable insights.

DIFFS

Redline comparisons

The AI generates a side-by-side view of text changes. You see exactly where words were swapped or deleted.

HISTORY

Statute timelines

The agent pulls the full chronological history of a law. You can see every version that has existed.

ANALYSIS

Impact summaries

Your AI interprets the redlines to explain how a change affects the meaning of the law. You get the context behind the edits.

HUMAN

Legal verification

The AI provides the raw diffs, but you must verify the legal weight of the changes. You remain the final authority on the law's application.

The workflow

What your AI does when the request arrives.

The AI moves from finding the right law to highlighting the specific changes.

  1. Locate the law

    The agent searches for the specific federal statute you need and identifies all available historical versions.

  2. Select versions

    You tell the AI which two points in time you want to compare, and it prepares the data for comparison.

    get_statute_history

  3. Generate redlines

    The AI runs a direct comparison between the selected versions to find every textual deviation.

    get_redline_comparison

  4. Summarize changes

    The agent presents the redlined differences in a readable format, highlighting the most significant shifts in language.
