There are several ways to quickly Compare the differences between two contracts: Use text comparison tools: There are many specialized text comparison tools, such as Diff Checker, Beyond Compare, etc, which can highlight the differences between two text files so that you can see the differences at a glance.

Use a spreadsheet: If the contract content is primarily in table or list form, you can import the contract content into a spreadsheet software (such as Excel) and then use the Conditional Format feature to highlight different cells.

Use NLP technology: While NLP technology may not be used directly to compare entire contracts, you can use named Entity recognition (NER) or text classification techniques in NLP to quickly locate key information in a contract (such as amounts, dates, terms, etc) and then compare that information.

Clause by clause: If the contract does not contain much, you can also compare the terms of the contract clause by clause to make sure that you have not missed any discrepancies.

Professional assistance: For very complex contracts, it is recommended to have a legal professional assist with comparison to ensure that all discrepancies are accurately identified.

Finally, whatever method you use, make sure the comparison is accurate and complete to avoid missing any important differences.
