Expert Guidance by Cleanlab is a tool designed to enhance AI behavior by integrating human feedback, allowing AI agents to improve reasoning, communication, and understanding without the need for retraining. This system operates in real-time, enabling non-engineers to guide AI using natural language, similar to instructing a human teammate. By capturing moments when AI performance deviates, teams can provide targeted guidance that refines how AI agents handle tasks, such as confirming details in workflows, presenting information clearly, or interpreting user intent accurately. For instance, in customer support scenarios, this method has demonstrated a significant improvement in task success rates by converting human feedback into structured guidance entries that the AI reuses in similar situations. Cleanlab's platform automatically identifies and prioritizes AI failures, transforming feedback into context-aware advice that is injected into AI responses just-in-time, thereby maintaining high reliability and adaptability in dynamic environments.
