Case Nexus is an AI-powered caseload intelligence platform built for Georgia public defenders who manage hundreds of active cases. By loading a defender’s entire caseload into a million-token context window, the system identifies patterns that humans often miss, such as recurring unconstitutional stops by the same officer across unrelated files. The platform utilizes 60,000 tokens of extended thinking to flag speedy trial risks and constitutional violations. Through Cascade Intelligence, Claude acts as an autonomous investigator using nine specialized tools to pull case files, research statutes, and verify citations. To stress-test legal strategies, the system runs adversarial simulations by chaining three Claude sessions representing the prosecution, defense, and judge with over 80,000 tokens of reasoning. This 20,000-line project was built entirely with Claude Code, demonstrating high-capacity inputs and complex multi-phase reasoning.
