About Sentiment Analyzer

The Sentiment Analyzer scores text as positive, negative or neutral and breaks the result down sentence by sentence. Each sentence gets a number, a colour badge and the list of words that swayed it, so you can see exactly why a review was marked negative. Useful for triaging customer feedback fast. Everything is scored in your browser, with no account and no upload.

How to use Sentiment Analyzer

  1. Paste reviews, survey answers or social media comments into the box, one after another.
  2. Click Analyze sentiment, or simply pause typing and the results refresh on their own.
  3. Read the overall badge and score at the top, then the counts of positive, neutral and negative sentences.
  4. Scroll the sentence list to see each score and the exact words that produced it.

What people use it for

  • Sorting a batch of Amazon or Google reviews into problems to fix and lines worth quoting.
  • Checking the tone of a complaint reply or customer email before you send it.
  • Tracking whether feedback after a product launch is leaning positive or negative.
  • Doing a quick first pass over free-text answers in a student or market survey.

Good to know

Scoring is lexicon-based: an English word list with values, adjusted for negations such as not and intensifiers such as very or extremely. It has no understanding of context, so sarcasm, irony, jokes and Hinglish or transliterated Hindi are frequently misread. Treat the score as a triage signal for sorting a pile of feedback, not as a verdict on any one sentence.

Frequently asked questions

How accurate is it?
Accurate enough to sort plain, direct English feedback into rough buckets. It misses sarcasm, comparisons and anything implied rather than stated, so read the flagged sentences yourself before acting.
Does it work on Hindi or Hinglish?
Not well. The word list is English only, so Hindi written in Devanagari scores as neutral and Hinglish registers only where English words appear. Translate the text first for a usable score.
What do the scores mean?
Each sentence adds up the values of the sentiment words it contains, so bigger numbers mean stronger feeling. Above 0.5 counts as positive, below -0.5 as negative, and everything between is neutral.
Is my feedback data private?
Yes. The word list and the scoring code are part of the page itself, so the text you paste never leaves your browser. Nothing is logged, stored or sent anywhere.
