FAQ
Can lawyers use ChatGPT or Claude for legal work?
Yes, but with important caveats. AI can assist with research, drafting, and analysis — but all legal work must be reviewed by a licensed attorney. Never cite AI-generated cases without verification. Both OpenAI and Anthropic's terms allow commercial use.
Which AI is better for legal research?
Claude is generally better for legal research because it's more careful with citations, less likely to hallucinate case law, and has a larger context window (200K tokens) that can process full case files. However, always verify AI-generated research with primary sources.
Is client data safe when using AI tools?
Claude doesn't use user data for training by default — better for client confidentiality. ChatGPT offers opt-out for data training. For maximum privacy, use the API with data processing agreements, or run open-source models locally via n8n.
Can I integrate ChatGPT or Claude into my law firm's workflows?
Yes. Both have APIs that can be integrated via automation platforms like n8n or Make. Common integrations: auto-drafting demand letters from case notes, summarizing medical records, generating client intake summaries, and creating research memos.
Which should a law firm choose?
For most legal work: Claude. Its larger context window, better instruction following, and privacy-by-default approach make it ideal for document-heavy legal workflows. ChatGPT works well for quick research and brainstorming. Many firms use both — Claude for serious work, ChatGPT for quick queries.
