Summary
General-purpose AI tools like ChatGPT, Claude, and Gemini are impressive for casual use but carry unacceptable risks for professional legal work. Purpose-built legal AI systems — like Cassandra Research — use RAG architecture grounded in authoritative legal sources to deliver cited, verifiable analysis suitable for professional practice.
Side-by-Side Comparison
| Feature | Purpose-Built Legal AI | General-Purpose AI |
|---|---|---|
| Citation accuracy | Grounded in primary sources | Frequently hallucinated |
| Jurisdictional coverage | Specific to target jurisdiction | Inconsistent |
| Source verification | Traceable to legislation/case law | Not traceable |
| Professional suitability | Designed for legal practice | Consumer-oriented |
| Confidentiality | Professional data handling | Varies by provider |
| Update frequency | Aligned with legal changes | Periodic retraining |
The Risk of General-Purpose AI in Legal Work
Lawyers who rely on general-purpose AI risk citing fabricated cases, providing incorrect legal analysis, and breaching professional conduct obligations. Several high-profile cases have already involved lawyers submitting AI-hallucinated citations to courts.
Frequently Asked Questions
Can I use ChatGPT for legal research?
