What is AI Sentiment Analysis?
Sentiment analysis uses artificial intelligence to detect the emotional tone of text - whether it's positive, negative, or neutral. This tool uses DistilBERT, a state-of-the-art transformer model trained on millions of text samples to understand language patterns and emotional context. It analyzes word choice, phrasing, and context to determine overall sentiment.
Sentiment analysis is widely used for analyzing customer feedback, social media monitoring, product reviews, survey responses, and brand reputation tracking. It helps businesses understand how people feel about their products or services at scale.

Common Questions
How accurate is AI sentiment analysis?
The DistilBERT model achieves 90%+ accuracy on standard sentiment benchmarks. It works best on clear, grammatically correct English text. Accuracy may vary with sarcasm, mixed emotions, or very short texts. The confidence score helps you understand how certain the AI is about each prediction.
What languages does it support?
This model is trained primarily on English text and works best for English language analysis. While it may produce results for other languages, accuracy will be significantly lower. For other languages, consider using language-specific sentiment models.
Is my text data uploaded to a server?
No. The entire AI model runs in your browser using Transformers.js. Your text is processed locally on your device and never transmitted to any server. This ensures complete privacy for sensitive content like customer feedback or confidential communications.
Why is there a download on first use?
The first time you use the tool, it downloads the DistilBERT model (~70MB) to your browser cache. This one-time download enables all future analysis to happen instantly without any server communication. The model stays cached, so subsequent uses are immediate.
Can I analyze multiple texts at once?
Currently, the tool analyzes one text at a time. For batch analysis of multiple texts, you'd need to analyze each one individually. The analysis is very fast (typically under 1 second), so processing multiple items is still quick.
What does the confidence score mean?
The confidence score (0-100%) indicates how certain the AI is about its prediction. A score above 80% suggests strong confidence. Lower scores (50-70%) may indicate mixed sentiment or ambiguous text. The AI always picks the most likely sentiment, but the confidence tells you how sure it is.
