Honest note: most websites block cross-site fetching (CORS), so this often fails. If it does, just copy the page text and paste it above.

Frequently asked questions
What is TF-IDF?
TF-IDF (term frequency, inverse document frequency) scores how important a word is to a document. Words that appear often in your text but rarely elsewhere score highest. It is a classic information retrieval formula, not a Google ranking factor.
How does single-document mode work without a corpus?
Honestly, it is an approximation. With one document there is no outside corpus, so each sentence acts as a mini-document for the IDF part. For true multi-document TF-IDF, use compare mode with 2 to 4 documents.
Is my text sent anywhere?
No. All computation happens in your browser with JavaScript. Your text never leaves your device, and the URL fetch goes directly from your browser to the target site.
