Case Brief Generator
Built From Real Opinions

Most tools ask a model to invent a brief from a case name. This one looks the case up. Whole brief, key terms, and the precedent behind it.

Two very different things get called a case brief generator

Generated from a model. You give it a case name and it writes a brief from whatever the model absorbed in training. No opinion is retrieved. The output is a plausible reconstruction, which is fine when the case is Palsgraf and unreliable when it is a state appellate decision your professor picked precisely because it is unusual.

Retrieved from a database, then structured. The system pulls the actual opinion and organizes it into brief form, so the facts, posture, holding, and citation come from the real text. That is what this tool does.

The distinction matters more than any feature list. A generated brief can be confidently wrong about which party won. A retrieved brief can be shallow, which is a far less dangerous failure. Before trusting any tool, ask it for a case you already know well. If the details drift, it is generating rather than retrieving.

What a brief has to contain to survive a cold call

  1. Procedural posture. Who sued whom, what happened below, how the case arrived at this court. Professors open with this constantly and generated briefs are weakest here.
  2. The facts that mattered. Not a summary of the fact section. The three or four facts the reasoning actually turns on.
  3. The issue as the court framed it. Most generated briefs state the issue at textbook altitude and miss the narrower question actually answered.
  4. The holding, in one sentence, with the disposition.
  5. The reasoning, including the argument the court rejected. Dissents matter when your professor assigned them.

The failure modes worth checking for

Invented citations are the consequential one. Models trained on the open web produce correctly formatted citations for cases that do not exist. Two New York attorneys were sanctioned in federal court in 2023 for filing a brief built on such cases, and similar incidents have followed in many jurisdictions. For a student, a fabricated cite in a graded assignment is academic misconduct at most schools, and intent is usually not a defense.

The wrong version of the case. Casebooks print heavily edited opinions, so a tool working from the full text may emphasize a section your book cut. Majority-rule drift is subtler: generated briefs gravitate to the general rule, which quietly flattens the minority position your professor assigned the case to teach. And reasoning that reads like a conclusion (“the court held X because the elements were satisfied”) cannot be reproduced on an exam.

To check any brief in about two minutes: confirm the citation exists in Google Scholar or CourtListener, check the disposition, compare the brief's issue statement to the court's own, and skim your casebook's note questions to see whether the brief covers what your professor will ask.

How to actually use it

As a first draft, a brief you did not write saves real time. As a replacement for reading, it produces a student who can recite a holding and cannot answer a follow-up, which is exactly what cold calls are built to find. The version that works: read the case, brief it yourself quickly, then use this as a second reader to catch what you missed. If you would rather write your own from scratch, the case brief template is free, and how to brief a case walks through the method.

Frequently asked questions

Is this an AI case brief generator?+
Not in the usual sense. Most tools ask a language model to write a brief from a case name, which is how invented citations and wrong holdings happen. Case Cub returns a brief built from the real opinion, so the citation and disposition are the actual ones.
Is it free?+
The brief is free and needs no account: facts, procedural history, issue, holding, rationale, judges' opinions, the key terms glossary, and the precedent the court relied on. What the free trial adds is the study layer built on top of it, meaning the plain-English rewrite, the answers to the exam questions, and the quiz and flashcards generated from the case.
What if my case is not in the library?+
The library covers 20,000+ cases, which includes essentially all of the 1L canon. If a case is missing, check the spelling of the caption first, since many cases are indexed under a longer official name.
Can I use a generated brief for class?+
Use it the way you would use any brief you did not write: as a check on your own reading, not a replacement for it. Cold calls are built to find the difference, and the reading is where the learning happens.
Are AI case brief generators accurate?+
It depends entirely on whether the tool retrieves the real opinion or generates a brief from a case name. Generated briefs can be confidently wrong about the holding or the disposition. Retrieved briefs may be shallow, which is a much safer failure.
How do I check a case brief I did not write?+
Confirm the citation exists in Google Scholar or CourtListener, check the disposition, compare the brief's issue statement to the court's own, and skim your casebook's note questions to see whether the brief covers what your professor will ask.
