What is the Comparison feature?

The Comparison feature lets you check for differences between contract files.

You can:

✅ Compare different versions of the same contract (version-to-version)
✅ Compare a contract with a similar contract (similar contract comparison)

Comparisons can be:

Compare full text: Check the entire text.
Compare by article: Match and compare each clause individually.
