How it works

1

Paste citation or text

A short citation like "410 U.S. 113" or the full opinion pasted from anywhere.

2

We find the opinion

Citations are looked up in Ark's 9.5M-opinion database. Or we work straight from your pasted text.

3

Structured case brief

Holding, facts, issues, rules, disposition, and key quotes — in plain English.

Looks like a real case brief

Facts, issues, rules, holding, disposition — the same sections you'd write for law school or a memo.

9.5M opinion database

Paste a citation and we pull the opinion from Ark's federal + 50-state case law index.

Fallback to paste

If the citation isn't in the DB, paste the full opinion text and we'll summarize it directly.
