Frequently Asked Questions

What is an Example of Legal Software Usage?

In-house counsel use legal software such as Spellbook to automate contract review, reduce contract turnaround times, and identify contract risks using AI. The software instantly flags issues such as unfavorable clauses, missing provisions, or non-standard terms.

What is the 30% Rule in AI?

The 30% rule is an informal guideline suggesting that AI should handle approximately 30% of routine legal tasks while in-house counsel focuses on complex analysis. However, this is not a standardized rule. Corporate legal departments should determine appropriate AI usage based on their specific needs.

Can ChatGPT Act as a Lawyer?

ChatGPT cannot act as a lawyer because it lacks legal-specific training and the attorney-client privilege required by corporate legal departments. Entering sensitive information into general-purpose AI tools creates confidentiality risks that are avoided when using purpose-built legal AI platforms.
