Node-AI is a no-code AI development tool developed by NTT Communications, designed for time-series data analysis. It allows users to build custom AI models through a browser-based interface by connecting modular components called "cards" without the need for programming skills. The platform supports tasks such as regression, anomaly detection, and causal analysis, making it suitable for applications in manufacturing, infrastructure, and environmental monitoring.

For example, Sumiyoshi Industries utilized Node-AI to develop a water quality prediction model, achieving a prediction accuracy within ±0.2 pH units, which led to a reduction of approximately 504 labor hours and over 1 million yen in annual labor costs.

Node-AI also offers visualization tools and collaborative features to facilitate efficient AI development and deployment.
