Frequently Asked Questions
How does keyword extraction work?
This tool uses a TF (Term Frequency) algorithm to score each word by how often it appears relative to the total word count. Common stop words (the, is, and…) are filtered out, leaving only meaningful terms.
What are stop words?
Stop words are common function words like 'the', 'a', 'and', 'is', 'in' that appear in almost every text and carry little meaning. They are filtered out so only relevant keywords appear in the results.
Is my text sent to a server?
No. All keyword extraction is performed entirely in your browser using JavaScript. Your text never leaves your device.
Can I use this for SEO keyword research?
Yes, as a starting point. It helps identify the main topics of a piece of content. For deeper SEO research, combine it with search volume data from tools like Google Search Console or Ahrefs.
