How to use it

How to use text diff

Compare two blocks of text line by line and separate additions, removals, and unchanged lines.

Compare two contract clause drafts before sending a revision.

  1. Enter or paste the values you want to work with.
  2. Review the result and any validation message.
  3. Copy or download the result when the tool provides that action.
