## Summary

International law firm Cooley has developed GO Public, a proprietary AI tool built on ChatGPT Work to streamline initial public offering (IPO) preparation. The tool uses an agentic harness to analyze client information, public sources, and past precedents. This system creates a tailored starting point for lawyers to review, rather than requiring them to manually sort through large volumes of information.

Cooley's innovation and legal teams designed the agentic harness to enforce a controlled workflow. This workflow specifies which tasks the AI agents can perform automatically and where human lawyers must validate the work. The firm aims to redirect lawyer and client management time away from manual sorting and toward strategic decision-making and professional judgment.
