Was ist Sentiment Analyzer?

This analyzer uses a compact local model loaded into your browser on first use. The model classifies each sentence as positive or negative with a confidence score, and the tool aggregates the per-sentence results into an overall label.

Inference happens locally. The text never leaves the device, and the model weights are cached in the browser after the first run.

So funktioniert es

  1. Paste your text

    A paragraph, an email draft, a review, a tweet — anything up to a few thousand words.

  2. Click Analyze

    The first run downloads the model. After that it is cached and runs offline.

  3. Read the breakdown

    Each sentence is labeled with its sentiment and confidence. The aggregate label at the top is the dominant tone across the whole text.
