We present a progressive summarization system for customer support agents. This system intelligently generates concise key points during conversations, reducing agents' context switching efforts and unnecessary review. It uses a fine-tuned Mixtral-8x7B model to perform continuous note generation and a DeBERTa-based classifier to filter out trivial content. Agent edits influence online note generation and offline model retraining, forming a feedback loop for agent edits. In a real-world operation, the system reduced case handling time by 3% compared to batch summarization, and by up to 9% for complex cases. Furthermore, surveys have shown high agent satisfaction.
