# Build a White-Label AI Legal Research Assistant

- Tool: AI Implementations
- Last updated: June 2026

## TL;DR

Legal research AI costs $200–$2,000/mo via SaaS, $18K–$35K via custom build (6–12 weeks), or $100/mo via Lovable DIY. Recommended: hire-agency for multi-tenant, compliance, and integrations with practice-management software.

## Frequently asked questions

### How much does it cost to build an AI legal research assistant?

A custom white-label build with RapidDev is $18,000–$35,000 (8–12 weeks). This includes foundation LLM integration, database querying, privilege classification, and attorney review workflow. If you need Westlaw API integration or fine-tuned privilege models, budget an additional $5,000–$10,000. Operating costs (Supabase, Westlaw API, Claude) are typically $300–$800/mo for a 50-attorney firm.

### How long does it take to ship this?

An MVP (Google Scholar + Claude memo synthesis) takes 1–2 weekends with Lovable. A production-grade system with Westlaw integration, privilege classification, and attorney sign-off workflow takes 8–12 weeks. Most of the time is integration testing and compliance review (work-product doctrine, GDPR audits).

### Can RapidDev build this for my firm?

Yes. We've shipped 600+ applications and 200+ AI implementations, including legal-tech platforms for mid-market law firms. We specialize in Westlaw/LexisNexis integrations, HIPAA-compliant privilege classification, and practice-management system connectivity (Clio, MyCase, Everlaw). Every build includes a 30-min free consultation to scope your specific workflow.

### Is AI legal research accurate enough to trust?

No. Claude hallucinates citations on edge cases — for example, 'Delaware tax-deferred ESOP sale-leasebacks' may return plausible-sounding but fictional case names. The system is best used as a research *accelerator*, not a replacement for attorney judgment. Mandatory attorney sign-off on every memo is table stakes. We recommend: AI synthesizes 5–7 cases into a draft memo, attorney reviews, attorney verifies citations against Westlaw/Scholar, attorney approves and signs. This 3-step process catches 95%+ of errors.

### What's the risk of unauthorized practice of law?

High, if you market the system as providing 'legal advice.' Your memos must be framed as 'research assistance for attorney review only.' Add this disclaimer to every memo: 'This research was generated by AI and is not legal advice. Licensed attorney review required.' Consult your state bar ethics hotline before launch — most offer free pre-submission reviews and can approve your UPL mitigation strategy.

### Can I integrate this with Westlaw or LexisNexis?

Yes, if your firm has an institutional subscription. Thomson Reuters (Westlaw) and Relx (LexisNexis) both offer APIs, but white-label resale is typically prohibited in their standard terms. You must negotiate a custom contract with their enterprise sales team (6–12 month process). Fallback: use free Google Scholar + state statute APIs (loses prestige/coverage but is 100% legal and cost-effective for solo practitioners).

### What about data privacy — GDPR, CCPA, work-product privilege?

Use Supabase or AWS Bedrock with a signed BAA. Implement role-based access (only the attorney can see their memos), audit logging on every access, and data residency controls (EU data stays in EU, California data in US). Work-product doctrine + privilege = no auto-deletion of approved memos (confict with GDPR right-to-erasure, but legal hold wins). Consult your in-house counsel before launch; privacy law + legal hold overlap is complex.

### What's the cheapest white-label SaaS option?

No honest cheap white-label legal research SaaS exists. Westlaw/LexisNexis APIs are institutional-only (price on request, typically $1,000–$5,000/mo). Consumer-tier AI (ChatGPT, Anthropic Console) are unreliable for legal research (hallucinations, no privilege awareness). Your best cheap path is Lovable DIY ($75/mo base cost) + free Google Scholar, but you'll sacrifice coverage vs. Westlaw/LN. For agencies serious about resale, hire custom build (breakeven at 20+ clients).

### Can I clone Westlaw's functionality and use my own LLM?

No. Westlaw/LexisNexis case law databases are copyrighted and not licensed for cloning. You'd need to: (1) negotiate database licensing from Thomson Reuters/Relx (enterprise deal, $50K–$500K+/year), (2) verify that your LLM training data doesn't include copyrighted case summaries, (3) implement your own citation verification + precedent-strength ranking (complex ML, 6+ months). Most agencies don't do this; they negotiate Westlaw API access instead.
