Common Issues

Sentiment seems wrong?

The AI may struggle with sarcasm, irony, or very nuanced language. For best results, use straightforward text.

Neutral result for clearly emotional text?

Very short text or mixed emotions may result in neutral classification. Try analyzing longer passages for more accurate results.
