Compare the states on one clause
Pick a clause family. You get one card per state: what that state's law does to the clause, the trap that makes a clause drafted elsewhere fail there, and every authority behind it with the sentences that state the rule quoted word for word. Free, no account, nothing to install.
What is on these pages, and what is not
A state appears for a clause family only when we have a rule whose every authority was checked: the quoted sentences were re-read, word for word, in the opinions and statutes we publish free on Hugging Face, so anyone can re-run the check. A family a state is missing from is a family we do not answer for it. We do not fill the gap with a neighbouring state's rule or with “generally”.
Each rule also carries how recently it was read, and against which reading bar. The bar has moved as we found new ways for a rule statement to be wrong, so a rule read at an older bar is not a rule that passes the current one, and the page says which it is. 584 of 602 rules have been read at the 2026-10-03 bar so far.
Newest rule statement here is as of 2026-10-08. This is research, not advice, and it is not a substitute for reading the authority yourself, which is why the authority is on the page.
