Operagents is an AI vision system for operator-guided, step-by-step manual operational and assembly guidance and quality inspection, learning instantly from human feedback for real-time improvement and continuous learning in open manufacturing environments. Traditional AOI systems require engineers to tune pixel-level parameters, control lighting, and design custom fixtures, making them rigid, slow to deploy, and prone to errors. Operagents removes these barriers with instant learning (one-/few-shot) and human-in-the-loop learning that updates AI during operation. Operators without programming skills can set up and refine AI models directly on the line, turning feedback into continuous improvement. It runs on edge using standard or industrial PCs and UVC cameras, and can be quickly deployed while maintaining high accuracy. It can integrate with the Memorence trainable enterprise knowledge base and with customer SOP documentation for vision-language contextual learning for decision support. Operagents delivers efficient, scalable, high-quality improvement across manual operations in global manufacturing.
