    • 2. AI Contract Review Workflow

    Preliminary Review with ChatGPT/Claude

    
I need to review the following contract ([contract type]), please help me:
  • Identify clauses unfavorable to me (focus on:
    • 
   - Limitation of liability clauses
   - Whether liquidated damages are reasonable
   - Intellectual property ownership
   - Scope of confidentiality clauses
   - Contract termination conditions)
  • For each risky clause:
    • 
   - Explain the risk
   - Suggest modification direction
   - Reference industry standard wording
  • Overall risk rating (High/Medium/Low)
    • [Paste contract text]
    Note: I am a legal professional, this is an auxiliary tool, final judgment is mine.

    Spellbook Contract Drafting Process

  • Install Spellbook plugin in Word
  • Describe contract needs: "I need a SaaS service agreement,
    • seller is my company, key protections: IP, limitation of liability, data security"
  • Spellbook generates initial draft of clauses
  • Review clause by clause, modify non-compliant ones
  • Compare with industry standard contract templates

    • 3. Limitations of AI Legal Tools (Very Important)

    What AI Cannot Replace:

  • Legal judgment (AI can only flag risks, not give legal opinions)
  • Litigation strategy (requires lawyer's experience and creativity)
  • Negotiation skills (involves interpersonal relationships and psychological games)
  • Understanding of judicial practice (differences in court rulings across regions)

    • Risks to Be Aware Of:

  • AI may cite non-existent precedents (hallucination issue)
  • Legal updates lag (AI training data has cutoff dates)
  • Insufficient understanding of industry practices and local regulations

    • Usage Principle: AI assists with drafts and checks, lawyers do final review
