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
