Frequently Asked Questions

Find Quick Answers

What file formats does the analyzer support?

The analyzer currently supports plain text files (.txt) for upload. You can also paste any text directly into the textarea.

How accurate is the sentiment analysis?

Sentiment analysis uses backend AI processing to detect positive, negative, or neutral tones in text. Accuracy depends on the clarity and context of the input, but it provides reliable results for general content.

Can I analyze large documents?

Yes, the tool can handle documents up to 10MB in size. For optimal performance, we recommend analyzing text under 50,000 characters for real-time processing.

Is my data stored or shared?

No, all analysis is processed in real-time and your data is not stored on our servers. For backend processing, data is temporarily held only during the analysis and then discarded.
