    About Sentiment Analyzer

    This sentiment analyzer uses the AFINN lexicon approach to determine the emotional tone of text. It identifies words with positive or negative connotations and calculates an overall sentiment score. Perfect for analyzing reviews, social media posts, customer feedback, or any text where understanding emotional tone matters.

    Sentiment analysis is used by 80% of Fortune 500 companies for customer experience management (Gartner 2024). It helps businesses understand public opinion, track brand perception, and identify customer pain points automatically.

    Frequently Asked Questions

    How does sentiment analysis work?

    This tool uses the AFINN lexicon, a curated list of words rated for sentiment from -5 (most negative) to +5 (most positive). Each word in your text is matched against this lexicon, and the overall sentiment is calculated based on the combined scores.

    What is the AFINN lexicon?

    AFINN is a sentiment lexicon developed by Finn Arup Nielsen. It contains over 3,000 English words, each assigned a sentiment score. It's widely used for basic sentiment analysis in social media, reviews, and other text data.

    How is the sentiment score calculated?

    The tool sums the AFINN scores of all recognized words, then normalizes the result to a -1 to +1 scale. Positive scores indicate positive sentiment, negative scores indicate negative sentiment, and scores near zero are neutral.

    Is my text data private?

    Yes, all sentiment analysis happens entirely in your browser. Your text is never sent to any server. This ensures complete privacy for your data.

    Privacy First

    All sentiment analysis happens in your browser. Your text never leaves your device.
