Short answer

How can I use my AI to find differences between two contract drafts?

Your AI pulls the specific documents you need and runs a comparison to flag every change. You'll get a clear breakdown of what was added, removed, or modified.

The results of the comparison.

Where the changes land.

The AI processes the drafts and organizes the output into these categories.

ADDITIONS

New language detected

The AI identifies every new clause or sentence inserted into the second draft. You get a list of exactly what was added.

DELETIONS

Removed provisions

The AI flags sections that existed in the original but are missing from the new version. This ensures nothing was quietly stripped out.

MODIFICATIONS

Changed wording

The AI spots when a clause wasn't removed but was instead rephrased. It highlights the shift in meaning or scope.

HUMAN REVIEW

Final legal check

The AI presents the findings for you to review. You make the final call on whether the changes impact your legal position.

    You tell the AI which specific documents to pull using their names or IDs, and it uses the connector to fetch them.
