Emotion Analysis
How AI Emotion Detection Works in Your Browser
This tool uses a deep learning image classification model running directly in your web browser via Transformers.js. When you upload a photo or capture one from your webcam, the AI analyzes facial features like eyebrow position, mouth shape, eye openness, and overall facial muscle patterns to determine the expressed emotion. The model classifies faces into seven basic emotions: happy, sad, angry, surprised, fearful, disgusted, and neutral.
The entire analysis happens locally on your device. The AI model is downloaded once (approximately 90MB) and cached in your browser for instant offline use. No image data is ever sent to any server, making this tool completely safe for personal and sensitive use.
Detectable Emotions
- Happy — Smiling, laughing, joyful expressions
- Sad — Frowning, downturned mouth, sorrowful looks
- Angry — Furrowed brows, clenched jaw, intense gaze
- Surprised — Wide eyes, raised eyebrows, open mouth
- Fearful — Widened eyes, tense expression, raised inner brows
- Disgusted — Wrinkled nose, raised upper lip
- Neutral — Relaxed face with no strong expression
