Legal work is language-intensive—exactly what AI does well. Use AI for efficient grunt work while lawyers handle strategy and judgment.

- Suggestions: Proposed redlines
Legal Research
AI finds precedent:
- Case law search: Relevant cases
- Statute reference: Applicable laws

Confidentiality Requirements
Critical for legal AI:
- Self-hosted: Run AI on your servers
- Enterprise agreements: Vendor data agreements
- Redaction: Remove sensitive info before AI
- Access controls: Limit who can use AI tools
Never: Input client data into consumer AI (ChatGPT free, etc.)
Billing Transparency
Ethical considerations:
- Disclose AI use: To clients if asked
- Appropriate billing: Don't bill AI time at attorney rates
- Value pricing: Consider fixed fees for AI-assisted work
- Client communication: Explain efficiency benefits
What AI Can't Do in Law
- Practice law: AI provides information, not legal advice
- Court representation: Only lawyers
- Final judgment: Lawyer must review AI output
- Client relationships: Humans build trust
Example Use Case
Corporate deal review:
- AI analyzes draft agreement
- AI flags deviations from firm playbook
- AI produces summary with marked issues
- Associate reviews AI analysis
- Associate adds strategic judgment
- Partner reviews and approves
