How does keyword extraction work?

The tool counts word frequencies in your text, filters out common stop words (the, and, is, etc.), and ranks the remaining words by frequency and relevance using a TF-IDF-inspired scoring approach. It runs entirely in your browser.

What is keyword density?

Keyword density is the percentage of times a word appears relative to the total word count. A density of 1-3% for a target keyword is generally considered healthy for SEO. Higher densities may be seen as keyword stuffing.

Can I export the keywords?

Yes. Use the Copy CSV button to copy the keyword list to your clipboard, or click Download CSV to save it as a file you can open in Excel or Google Sheets.

What is the word cloud view?

The word cloud shows keywords sized by frequency — more common words appear larger. It gives a quick visual overview of your content's main themes.

Does my content get uploaded anywhere?

No. All processing is done in your browser with JavaScript. Your content never leaves your device.

What is the difference between a keyword and a key phrase?

A keyword is a single important word. A key phrase (or long-tail keyword) is a 2—4 word combination that carries specific meaning. Both are important for SEO and content analysis.

How are keywords scored?

Keywords are scored by frequency (how often they appear), position (words appearing earlier or in headings score higher), and contextual weight (words in noun phrases score higher than isolated words).

Is my text sent to a server?

No. All extraction runs in your browser using JavaScript NLP algorithms. Your text never leaves your device.
