Why it holds up

Answers you can check, not trust.

American authority is famously voluminous: a federal system with the US Supreme Court, thirteen courts of appeals and the district courts sits alongside fifty state court systems, each with its own apex court. Circuits split, states diverge, and much of the best research tooling sits behind expensive subscriptions, so confirming what the law actually is in a given forum can be slow and costly.

LexChat starts with retrieval over reported US cases and legislation, then reasons only from the material it found — it does not fill gaps with guesses. Every answer is pinned to citations you can open and verify, which matters in a system where the rule in the Ninth Circuit may not be the rule in the Fifth.

The court system

United States's courts, ready to query.

01

US Supreme Court.

The apex of the federal judiciary and the final word on federal law and the US Constitution. It hears a small, selective docket, mostly on writ of certiorari, and its holdings bind every other court in the country.

02

Courts of appeals.

Thirteen federal circuits sit between the district courts and the Supreme Court. Their published decisions bind the district courts within each circuit, and splits between circuits are a classic reason the Supreme Court takes a case.

03

District courts.

The federal trial courts, where federal cases are filed, tried and first decided. Their opinions are persuasive rather than binding, but they are often where a developing legal question gets its first serious airing.

04

State courts.

Each of the fifty states runs its own court system with its own apex court, the final authority on that state's law. Most American litigation happens here, which is why state authority matters so much in practice.

How it works

From question to authority in three steps.

01

Ask in plain language.

Describe the issue the way you would to a colleague — no query syntax, no database codes, no guessing at keywords.

02

Retrieval before reasoning.

LexChat searches US sources first, and reasons only over what it actually found.

03

Citations you can open.

Answers arrive pinned to decisions and provisions. Open the source, confirm the holding, and cite it with confidence.
