Legal research with receipts. Built deep, jurisdiction by jurisdiction.

LawEngine is built for lawyers who need source records in view: source links, dates, verification boundaries, and deterministic primary-law checks where coverage exists. No AI sits in that deterministic verification path.

Free to try - no card.

Source records you can inspect

SourceStored record before model gloss

DateEffective, source, or checked metadata where available

BoundaryWhat LawEngine checked and what stays attorney review

Not a vague coverage map. A source-control method.

The homepage stays broad. The product page shows the proof exhibit: build one jurisdiction deeply, connect the federal workflow, then expand state by state without pretending the new state is finished before the source records exist.

Illinois, proof exhibit

This is where the product shows what deep means.

  • ILCS and Illinois Constitution
  • Supreme Court Rules and Rules of Evidence
  • Illinois opinions in the research workflow
  • Administrative-code source records
  • Scoped Chicago local-law support
  • Legislation records and Public Act trails

Federal, in the workflow

Federal primary law is not a footnote.

  • U.S. Code refreshed from OLRC release points
  • CFR/eCFR in the active legal-text workflow
  • Federal Rules and U.S. Constitution
  • SCOTUS and federal circuit opinions
  • District-court semantic coverage stays caveated

New York, active where supported

The expansion method stays source-controlled.

  • Search support where public workflow coverage exists
  • New York statutes and city sources where supported
  • Regulation/source-control work is the next deeper proof lane
  • Public copy avoids Illinois-depth parity until the source work supports it

Outside current coverage, LawEngine keeps the edge visible instead of guessing.

The brag is the boundary.

LawEngine is built for accuracy and transparency where coverage exists. It shows source records, dates, and limits because lawyers need the edge of the system as much as the answer.

500/500 on a public citation-grounding benchmark.

Task-specific proof on the open citation-grounding pack. It does not prove every answer, source, or case quote is perfect.

View benchmark methodology

Some legal tasks should not be guessed.

  • No blanket good-law treatment status.
  • Public case verification is source-record oriented unless a case-quote lane ships.
  • LawEngine is research support, not legal advice.
