Frequently Asked Questions

What is the best AI tool for lawyers?

Claude Pro (83/100) handles legal drafting tasks best in our tests — NDA review, contract clause generation, and document summarization are strong use cases. Critically, verify all legal references; Claude had a 6% hallucination rate on specific case citations, which is too high for reliance without verification.

Which AI tools help with legal research?

Perplexity AI (80/100) is better than ChatGPT for legal research because it cites real sources. However, for authoritative legal research we recommend Westlaw or LexisNexis — AI tools are useful for preliminary orientation, not final research. Never cite AI output in court filings without independent verification.

Is it ethical for lawyers to use AI?

Most bar associations permit AI use with proper human oversight. Rules require lawyers to understand the tools they use (competence), avoid disclosing confidential client information to public AI systems, and personally verify AI-generated legal content. Check your jurisdiction's specific guidance before using AI in client matters.
