GC AI powers legal workflows for 1,500 companies, saving lawyers 14 hours a week with Claude

The problem

In-house legal teams face a persistent ratio problem where each lawyer supports dozens of stakeholders with competing deadlines, and early AI tools required significant manual prompting and cleanup before outputs were usable, limiting practical value for busy legal teams.

First attempt

Before GC AI's current approach, legal AI systems required more manual prompting and editing to reach a useful result, and outputs often needed significant cleanup before they were ready, which limited practical value and failed to save time for lawyers.
