Frequently asked questions
How is the sentiment score calculated?
Each sentence is tokenized and matched against built-in positive and negative word lists. The score is (positive hits minus negative hits) divided by word count, so longer texts are comparable.
Is this as accurate as AI sentiment models?
It is a transparent lexicon method that runs fully offline in your browser. It catches clear tone well but misses sarcasm, negation flips, and context, so treat it as a quick signal, not a final judgment.
Does my text leave my device?
No. All scoring happens in JavaScript in your browser. Nothing is uploaded or stored anywhere.
