Description

We built tooling that connects LLMs directly to case law databases with citation verification to address hallucination in legal AI. Think of it as giving the model access to actual legal sources instead of relying on training data.

Could you build this?

Partial The search and chat interface is standard, but reliably ingesting, parsing, indexing, and validating millions of primary legal court opinions and citation networks requires specialized legal datasets and citation graphs.

What it would actually take: A functional production version requires a massive vector and relational search pipeline ingesting normalized legal corpora (such as the Free Law Project / CourtListener data), backed by Milvus/Elasticsearch and PostgreSQL. The hardest technical piece is building an authoritative legal citation extraction and Shepardizing/KeyCite verification engine that accurately traces precedents, overruled holdings, and pinpoint page citations without hallucination. This requires legal informatics specialists, high-throughput ETL infrastructure, and curated legal metadata partnerships.

Discussion

10 comments analyzed.

Competitors mentioned: Lexis and Westlaw (incumbents with case treatment/Shepardizing), ChatGPT and Gemini (grounding/source linking), vLex, Bloomberg

Concerns raised: Hallucinations in case holdings and citations (fabricated, wrong, or misattributed), Massive undertaking to cover U.S. Federal, State, and Administrative hearings properly, Court data access challenges: bad formats, paywalls, slow publishing, physical courthouse visits required, Unclear differentiation from uploading documents to general-purpose LLM with source citations, Misleading use of 'open' and '.org' branding for for-profit business

Feature requests: Case treatment and issue categorization (like Shepardizing), Direct scraping from state legislature sites (vs. third-party sources like Justia), Broader coverage scope clarification: U.S. Federal, State, and Administrative hearings
