Questions

Is my brief stored?

No. Text and files are processed in memory and discarded when the report is returned. Only counts are logged. Privacy.

What can it not check?

Westlaw and Lexis identifiers, about a quarter of the citations in filed briefs. They are listed as unverifiable, never flagged. Statutes, regulations and secondary sources are not checked either. Coverage.

What is the deep check?

For every citation the register resolves, a judgment model reads the opinion and answers one question: does it say what you cited it for. It confirms about 7 in 10 good citations and is shown as a review queue with the passage, never as a verdict.

How do I pay, and how do I cancel?

Card, through Stripe. Cancel from the account page; the plan runs to the end of the period you paid for. Invoices are in the billing portal. Teams that need an invoice instead of a card: [email protected].

Is this legal advice?

No. It is a proofreader for citations. Read the authority before you rely on it.
