Questions People Ask
Honest answers about how this works.
How does it decide which words are keywords?
The tool scores each term by how often it appears relative to the rest of the text, then removes hundreds of common stop words such as the, is, and at. What remains is a ranked list of meaningful words and phrases that truly represent your content.
How many keywords can this tool extract?
The tool returns the strongest terms found in your text rather than a fixed number. Short inputs naturally produce fewer results, while long articles can yield dozens of ranked keywords. You can trim the list yourself and copy only the terms that matter for your project.
Does my text leave the browser?
No. Keyword Extractor processes everything locally in your browser using plain JavaScript. Your text is never uploaded to a server or stored anywhere, which makes the tool safe to use on unpublished articles, confidential reports, or client copy you are not allowed to share.
How are multi-word phrases handled?
The extractor looks at individual words and also detects common two and three word combinations. If new york appears repeatedly, it is reported as one phrase instead of separate new and york entries, giving you a much more accurate view of your content themes.
