TensorFlow is a fast, flexible, and scalable open-source machine learning library for research and production.

We chose TensorFlow.js for facial expression detection because it runs entirely in the browser, eliminating the need for server-side processing. That was critical for us to maintain EmotionSense’s core promise: full local processing and zero data exposure. Other libraries either lacked performance or required server dependencies that conflicted with our privacy-first approach.
