Frequently Asked Questions

Is Sentiment Analyzer really free to use?

What languages does Sentiment Analyzer support?

It works best with English, but the underlying AI model can generally handle many other languages as well, with results that may vary in accuracy.

How accurate is the sentiment analysis?

There's no fixed accuracy figure — results depend on the AI model's interpretation of context, and it can misjudge sarcasm or ambiguous phrasing like any sentiment analysis tool.
