Why LawEngine exists
Legal AI should not ask lawyers to trust a generated answer floating above the law. LawEngine starts with the record: primary sources, citations, deterministic checks, and workflows that make the evidence visible before a draft moves forward.
Method
How the engine works
Build from the courtroom up, not from the model down. The source record is the operating surface.
Trace the answer back to the record
Every serious answer should make the underlying authority visible. LawEngine is built to keep the record close to the work.
Verify when the words matter
Citation checks route through deterministic verification where source text is supported, so legal language is checked against legal language.
Today
What you can do today
Use the product where it is already concrete: legal research, citation verification, and document-level review.
Research a legal question
Ask a legal research question and inspect the statutes, rules, cases, and included federal authority behind the answer.
Start the engine →Verify a citation
Paste a short passage with a citation and see whether supported quoted law matches the cited source, appears elsewhere, or needs review.
Verify a citation →Verify a document
Upload a brief, motion, or memo to extract citation claims and route them through the document-verification workflow.
Verify a document →Proof
Precision and proof before persuasion.
LawEngine scores 100% on an open citation benchmark. GPT-5.4-mini scored 72% on the same task, same grading.
LawEngine deterministic lane
100%
500 / 500 correct
Deterministic verification on a 500-row open citation benchmark. No AI model sits in the verification path.
GPT-5.4-mini baseline
72%
Rounded public baseline
Rounded 72% baseline on the same 500-row open citation benchmark with the same four-label contract. It is a citation-grounding task, not a broad legal-reasoning claim.
