The Lawyer-AI Sandwich: Defining the Human-in-the-Loop Architecture


Listen Later

How do you translate years of legal intuition into a digital product? In this episode of AI Practice Notes, host Michael Fahner talks with Marla Miller, a tax attorney and the Founder/CEO of 9to5 Legal Docs, about the transition from practitioner to builder.

Marla shares her insights on why generic AI models often miss the mark in high-stakes legal work. They dive deep into the "Lawyer-AI Sandwich"—an architectural framework where the lawyer provides the initial context and the final strategic review, leaving the "messy middle" of drafting and data synthesis to the AI.

Whether you're a skeptic or an early adopter, this conversation is all about how to stay "in the loop" while still capturing the massive efficiency gains of modern technology.
