What a law student needs from a research tool.

Before comparing anything, decide what the tool is for. For a student it is learning the law, which asks different things of a tool than practising it does.

  1. Understanding, not just answers

    You need to know why a case matters, not only what it says. A tool that hands you a conclusion has done the part you are meant to learn.

  2. Cases that are real

    An invented citation is worse than none. Whatever you use, every case it gives you should be checkable against its source.

  3. The story, not a snapshot

    How did the law get here, and what changed along the way? That is what an examiner is testing, and what a list of cases leaves out.

  4. A price a student can carry

    Free to start, and cheap enough to keep, because the course runs all year.

  5. Something you use all year

    Week one to exam day, not a three-day sprint before the paper.

The kinds of tool you will meet.

Most students end up using more than one. Each kind is good at something different, and none of them is the whole job.

Your university's research databases

The full record: judgments, reports, journals and commentary, usually free through your library. Use them to open the full judgment and to confirm every case you rely on.

A general AI assistant

Good for putting a concept you half understand into plainer words. Check every case it names against the source before it goes near an essay.

A document summariser

Good for condensing judgments and readings you already have. It works from what you give it, so finding the right cases is still your job.

A library of ready-made case briefs

Quick orientation before a tutorial. But writing the brief yourself is where the learning happens, so treat someone else's as a starting point.

Where LexCases fits.

LexCases is a study tool, built by a law student for learning the law. It sits beside your library's databases, not in place of them: it helps you find your way in and understand what you find.

It starts from your problem

Describe the problem question in plain English. No case name or citation needed, and the cases come back ranked by how well each one fits.

It shows the doctrine's story

Interactive timelines show how a doctrine was built, case by case: what each decision changed, and what came after.

It checks every case before you see it

Anything that cannot be confirmed is dropped, so you get a shorter list rather than an invented one. The check is itself an AI process, so you still open the source before you cite.

Your notes stay yours

Save cases to your modules and write your own notes. The AI never writes them for you, and the Question Advisor guides your approach without writing the answer.

28 jurisdictions, on equal terms

The same effort and the same honesty for every jurisdiction. Where the public record is thin, the result is shorter and says so.

A score you can see inside

Each case carries an authority score out of 100, with the formula shown in the open. A supporting signal, never the reason to pick a case on its own.
