AI Emotion Analyzer

No. Nothing is uploaded. The model runs entirely in your browser through WebAssembly, so your text is analyzed on your device and never sent to a server. Only the model itself is downloaded, once, then cached.

It detects emotions using a zero-shot text classifier that runs in your browser. Zero-shot means the model scores your text against each emotion label (joy, love, anger, sadness, fear, and more) without being specially trained on an emotion dataset, so it stays flexible and runs from one small download.

It scores joy, love, gratitude, surprise, sadness, fear, anger, and disgust, plus a neutral baseline. Each emotion is scored independently, so the percentages do not add up to 100 percent and a single text can rank high on more than one emotion at once.

Sentiment analysis gives a single positive or negative verdict. Emotion analysis is finer grained: it tells you which specific emotions are present, so you can tell grateful from joyful, or anxious from angry, even when the overall sentiment is the same.

The AI model downloads the first time you use the tool, then is cached by your browser for instant reuse. After that, analysis is nearly instant for short text.
