Contract Clause Comparison Tool
When two versions of a clause or two suppliers' terms land on your desk, the first question is often which topics each one even mentions. This tool scans two pasted texts for eight common contract topics, from liability and indemnity to payment and warranty, and sorts them by where they appear. It checks keyword presence only; it is not a redline and not legal advice.

What this law tool gives you
The output is four short lines: topics in A only, B only, both, and in neither. Use it to spot a dropped indemnity or a new data clause at a glance, then read those passages closely. It is a triage step before a proper comparison, not a substitute for one.
What you enter
- Clause A: the first clause or contract text, pasted as plain text
- Clause B: the second clause or contract text, pasted as plain text
Worked example
Clause A in the example mentions a liability cap, termination for convenience and payment in 30 days. Clause B mentions indemnity, governing law of England and Wales, confidential information and payment terms net 30. The result: A only: Liability, Termination. B only: Indemnity, Governing law, Confidentiality. Both: Payment. Not found in either: Data, Warranty.
How does the clause comparison work?
The tool lowercases each text and looks for simple keywords for eight topics. Liability: "liability" or "liable". Indemnity: "indemnity", "indemnify" or "hold harmless". Termination: any word starting with "terminat". Governing law: "governing law" or "governed by". Data: "data" or "privacy". Payment: "payment" or "invoice". Confidentiality: "confidential". Warranty: any word containing "warrant".
A topic is marked present if any of its keywords appears anywhere in the text. Each topic is then placed in A only, B only, Both, or Not found in either. The tool does not compare wording, meaning or numbers.
Tips before you use the result
- A match is only a keyword. "No liability" and "unlimited liability" both count as Liability, so read every flagged passage.
- Substring matching can overreach: "database" counts as Data and "warrants" in a securities sense counts as Warranty.
- Two clauses that both mention Payment can still differ completely on amount and timing; Both means mentioned, not identical.
- Paste one section at a time for cleaner results; a whole contract will usually mention most topics.
Frequently asked questions
Is this a redline or document comparison tool?
No. A redline shows word-by-word changes between versions. This tool only checks whether eight contract topics are mentioned in each text, based on simple keywords. It is useful for spotting a missing or added topic quickly, but you still need a real comparison and a careful read before signing.
Which topics does the tool check?
Eight: liability, indemnity, termination, governing law, data, payment, confidentiality and warranty. Each has a short keyword list, such as "indemnify" or "hold harmless" for indemnity and "privacy" for data. The topics were chosen because they often move between contract versions.
Why does a topic show up when the clause excludes it?
Because the tool looks for words, not meaning. A sentence such as "neither party is liable" contains "liable", so Liability is marked present. That is by design: it points you to the passage, and you decide what it says. It is not legal advice.
Can I close the page and come back to the comparison?
Yes. Both texts are saved automatically in this browser, with no login, and they reload when you return on the same device. Nothing leaves your machine. Use Clear before pasting the next pair so old text does not mix with new.
