LawEngine

LawEngine is a legal research and citation-verification platform for attorneys, combining primary-source legal research with a deterministic system for checking cited authority.

Key features and functions include:

Primary-source research
LawEngine ingests and normalizes court opinions, statutes, regulations, and administrative records directly from government and court sources rather than relying on a licensed secondary corpus. Coverage is built jurisdiction by jurisdiction.

Hybrid search and retrieval
Research questions are answered using a combination of graph-based and semantic retrieval methods paired with a re-ranking stage intended to surface relevant authority.

Deterministic citation verification
A separate verification layer checks supported statute, regulation, and eligible stored judicial-opinion citations against the underlying source record, displaying the source, effective or checked date, and the boundary of what has been verified. The company states this verification layer does not rely on AI.

Brief and document verification
Users can upload a brief, motion, or memo (PDF, DOCX, TXT, or Markdown) so citations and quoted legal text in the document can be checked against covered sources. Uploaded documents are held in temporary private storage and deleted after processing under the standard workflow; a separate "Verify Brief" feature retains uploaded files and results for audit purposes with the user's consent.

Jurisdictional coverage
Illinois coverage includes the Illinois Compiled Statutes, Illinois Constitution, Supreme Court Rules, Rules of Evidence, administrative code records, scoped Chicago Municipal Code support, and legislative/Public Act tracking. Federal coverage includes the U.S. Code, CFR/eCFR, Federal Rules, U.S. Constitution, and Supreme Court and federal circuit opinions. New York coverage is in active expansion for state statutes and select city sources.

Transparency about limits
Result panels display the source record, relevant dates, and an explicit boundary statement describing what has been checked, distinguishing verified citation accuracy from an assessment of a case's current legal status or good-law treatment.
