Reading opinions

Finding the authorities that answer your question...

Sample answer. That question is outside the worked examples this preview ships with, so the authorities below show the format rather than an answer to what you typed. Pick one of the example questions above for a fully worked result.

Controlling statute

The controlling statute is surfaced alongside the case law so you read the code and the precedents together.

Authorities

CaseSearch shows you the sources. Always read the full opinion and verify citations before you rely on them.

Ask your own question and the console searches the reporters for real. The three worked examples show the shape of an answer while yours runs. CaseSearch is a research tool, not legal advice: you read the opinion, then rely on it.

Why CaseSearch

Built for the work, not the demo

Four things every answer gives you, so research that used to take an afternoon takes a few minutes.

01 No Boolean

Ask in plain English

No Boolean syntax to memorize. Ask the way you would ask a senior associate, and CaseSearch reads the question and finds the authorities that answer it.

02 Real citations

Every answer is cited

You never get an unsourced essay. Each result is a real, citable authority with the case name, reporter citation, court, and year, plus a plain-language holding.

03 Good-law signal

Know if it is still good law

Each cited case carries a treatment signal, Followed, Questioned, or Overruled, so you never brief a dead precedent by accident.

04 One-click memo

Statutes and a memo, together

The controlling statute appears next to the cases, and one click turns the answer into a formatted research memo ready to drop into a brief.

How it works

Ask, search, verify

Plain English in, cited authorities out, and you always read the opinion before you rely on it.

Step 01

Ask

Type a real legal question in plain English. No Boolean, no operators, no query language. Just the question you would ask a senior associate.

Step 02

Search

CaseSearch reads the opinions and statutes and finds the authorities that answer your question, ranked by how on point they are.

Step 03

Verify and export

Get cited cases with plain-language holdings and a good-law signal, the controlling statute, and a one-click research memo. Read the opinion, then rely.

FAQ

Questions lawyers ask first

CaseSearch is built to surface real, citable authorities and to show you the source for every answer, so you read the opinion and verify it before you rely on it. You never get an unsourced essay or an invented citation presented as fact. Every result is a real case with a reporter citation, court, year, and a plain-language holding, plus a treatment signal showing whether it is still good law. This show-the-sources, you-verify stance is the whole point of the product after studies found general AI legal tools still hallucinate citations.

No. CaseSearch is a legal research accelerator, not legal advice, and using it does not create an attorney-client relationship. You remain the lawyer. It finds and summarizes authorities so you can research faster, but you read the full opinions, apply judgment, and make the legal decisions. Always verify citations before relying on them.

CaseSearch covers federal and state case law and statutes, including U.S. Supreme Court and federal circuit opinions, state supreme and appellate decisions, and the federal and state codes that control an issue. You can narrow a question to a jurisdiction so the authorities you get back are the ones that bind your matter.

No. You ask a question in plain English, the way you would ask a colleague, for example, can a non-compete be enforced against a remote contractor in California. There is no Boolean syntax, no proximity operators, and no query language to memorize. That is the core difference from the older database-style tools.

CaseSearch gives you plain-English answers with cited precedents and holding summaries at a transparent, self-serve price a solo or small firm can actually buy. The enterprise tools are powerful but sit far higher: the two Westlaw prices Thomson Reuters publishes work out to 3,081 and 4,797 dollars a seat a year, LexisNexis runs 1,368 to 5,184 dollars a seat a year on its published tiers, and above three attorneys both are sales-gated and lean on Boolean search. CaseSearch is built for solos and small firms who do not have a five-figure research seat, with prices on the page and no enterprise contract.

CaseSearch publishes its prices rather than gating them behind a sales call. Solo is 24 dollars per month, Firm is 54 dollars per month, Practice is 124 dollars per month, and Enterprise is 249 dollars per month, billed yearly (49, 109, 249 and 498 dollars month to month). There is no contact-sales gate just to see a price, and no five-figure seat. The interactive research console on the site is free to try.
