Compare two versions of a contract

free

Paste the version you sent and the version that came back. Every changed passage comes out marked, under a summary of which kinds of clause the other side touched, so “they only cleaned up the language” can be checked rather than taken on trust.

Free, and it never leaves this browser

Two versions in, every changed passage out, each one labelled with the kind of clause it sits in. No account, no sign-in, and no model: the comparison is arithmetic over the two texts, run by code in this tab. Neither version is uploaded, neither is kept, and nothing is sent anywhere when you press Compare.

The earlier version

What you sent, or the version you already knew.

The later version

What came back, or the draft you are being asked to sign.

Both versions stay in this browser. There is no upload and no request: the comparison runs here, and closing the tab is all it takes to be rid of it.

Both versions are needed before there is anything to compare.

Paste or drop both versions above. Sections are found from the numbering and headings of each version, so one clause against its redraft works as well as a whole agreement against its amendment.

What this is not

This says what changed, not whether a change is safe. For that, contract review reads each clause against a state’s verified rules and the recorded traps (signing in required, and free), and the 50-state clause survey is the law behind those rules, open to everyone. Other free things here: a whole-brief citation check and deadline computation.
