Sentiment Analyzer — Free Text Utility

Sentiment Analyzer scans text against curated lists of positive and negative sentiment words, calculating an overall score and classification (Positive, Negative, or Neutral) along with the specific matched words that drove the result — a lightweight way to gauge the emotional tone of a review, social media post, customer feedback, or draft marketing copy before publishing it. This lexicon-based approach is fast and transparent (you can see exactly which words triggered the score) though it doesn't capture sarcasm, context-dependent meaning, or negation nuances the way advanced machine learning sentiment models can — making it best suited as a quick directional check rather than a definitive analysis for high-stakes decisions.
