Last updated: July 2026
A sentiment analyzer reads text and scores it on a positive-to-negative scale. It uses a large lexicon of words rated by emotional valence — positive words like 'excellent' or 'love' increase the score; negative words like 'terrible' or 'hate' decrease it. Neutral text scores near zero. Everything runs in your browser; no text is uploaded.
🔒 Runs in your browser using a sentiment lexicon — no text is uploaded, no AI API is called.
