Is my text uploaded anywhere?

No. The sentiment lexicon is bundled into this page and scoring runs entirely in your browser.

Which languages are supported?

The bundled lexicon is English. For best results, paste English text; mixed-language input is still scored using English word matches.

How accurate is this?

Lexicon scoring catches obvious positive and negative tone. For nuanced cases (sarcasm, negation) consider a transformer model — we plan to add a Transformers.js DistilBERT option.
