Quillio searches Australian and New Zealand case law, legislation, regulations, and practice notes — and gives you a citation on every answer so you can verify before you rely on it.
Quillio is an AI legal research tool built for Australian and New Zealand lawyers. It is trained weekly on AU/NZ legislation and case law across all eight Australian jurisdictions plus federal courts and NZ. Every research result includes a source citation linking back to the underlying authority — so you can verify the answer before relying on it. Built around the duty of competence, never around blind trust.

Researching the leading authority on a property settlement contribution argument takes 45 minutes — checking AustLII, reading three or four headnotes, and finding the case that actually applies to your facts.
Quillio surfaces the leading Family Court and Federal Circuit Court authorities in 60 seconds, with a one-paragraph explanation of how each applies and a citation linking straight to the judgment.

AU/NZ Legal Research FAQs
How does Quillio avoid the "fabricated cases" problem ChatGPT has?
Quillio is grounded in a verified AU/NZ legal corpus — it does not generate citations from general training data. Every research output includes a source citation linking to the underlying authority you can click through to verify. This is the core difference between purpose-built legal AI and general-purpose AI like ChatGPT, which has been documented to fabricate case citations in court filings.
How current is Quillio's case law coverage?
Quillio is updated weekly with new decisions across all Australian jurisdictions plus NZ. This includes High Court, Federal Court, Federal Circuit and Family Court, state Supreme Courts, intermediate appellate courts, and major tribunals. Recent unreported decisions and practice notes are also included.
Can Quillio do cross-jurisdictional research?
Yes. Ask Quillio to compare how the same issue has been treated in NSW vs Victoria vs Queensland, and it will surface the relevant authorities from each jurisdiction with a comparative summary.
Does Quillio cover NZ law?
Yes. Quillio includes full coverage of New Zealand legislation, case law, and regulatory updates — Supreme Court of NZ, Court of Appeal, High Court, and District Court decisions.
Can I get a research memo, not just an answer?
Yes. Ask Quillio for a research memo on a topic and it will produce a structured memo covering the legal framework, leading authorities, current trends, and a summary of how the law applies. Useful for handing to a partner or briefing counsel.
How is this different from AustLII or Lexis?
AustLII and Lexis are excellent legal databases for searching when you know what you are looking for. Quillio adds AI on top — you can ask the question in plain English and get a structured, cited answer rather than a list of search hits to read through. The two are complementary; many AU lawyers use AustLII for known-citation lookup and Quillio for question-led research.
Can I trust Quillio's research enough to cite in court?
Quillio gives you the citation; you check the authority before you cite it. That is the duty of competence cycle, and it is exactly how research should work whether the source is Quillio, AustLII, or a junior lawyer's memo. The difference Quillio makes is that the cycle starts with a structured answer rather than a search results page.
