Why LegiSearch

Legal Research, Reimagined

Research that once took hours now takes minutes — with citations you can trust.

3-5x Faster Research

Tasks that took 3-6 hours with manual research take 15-30 minutes with LegiSearch. The AI identifies relevant authorities, synthesizes holdings, and presents cited results.

Verified Citations

Every case cited is checked against real databases. No hallucinated citations — the #1 risk with consumer AI tools. Every citation includes a link to the source.

FAQ

Frequently Asked Questions

Common questions about AI legal research software.

LegiSearch uses Claude AI with retrieval-augmented generation (RAG). When you ask a legal question, the system retrieves relevant case law and statutes from verified databases, then synthesizes a cited answer. Every citation is verified — no hallucinated references.
LegiSearch is an AI-assisted research tool built into your case management workflow. It's ideal for day-to-day legal questions, case law lookups, and jurisdiction-specific queries. Some firms use it alongside traditional research platforms for specialized or exhaustive research needs. It's included in your Legience subscription ($99-249/mo) with no additional cost.
LegiSearch is included in every Legience plan. Starter ($99/mo) includes 200 queries/month, Professional ($169/mo) includes 500 queries/month, and Firm ($249/mo) includes unlimited queries. No per-query fees.
AI legal research is a research accelerator, not a replacement for attorney judgment. Every result should be verified by the attorney — just as you would verify research from an associate. LegiSearch verifies citations against source databases, but the attorney's professional duty of competence (ABA Rule 1.1) requires independent review.
Yes. AI queries are processed through AWS Bedrock under our Business Associate Agreement (BAA). Your data is never used for model training. AES-256 encryption at rest, TLS encryption in transit, US-only hosting.
