Question 1

How does the keyword extractor work?

Accepted Answer

The tool implements the YAKE (Yet Another Keyword Extractor) algorithm — an unsupervised, statistics-based method that scores each candidate word using five features: casing (capitalized terms score higher), term frequency, position (words near the start of the text matter more), term occurrence in sentences, and frequency normalized by word length and spread. Lower YAKE scores mean higher relevance. The tool also extracts multi-word keyphrases by grouping adjacent scored terms.

Question 2

What is the difference between single keywords and keyphrases?

Accepted Answer

Single keywords are individual scored words. Keyphrases are 2-4 word combinations of adjacent high-scoring terms that appear together — for example 'machine learning' or 'free online tool'. Keyphrases often capture concepts more precisely than single words.

Question 3

How do I use the extracted keywords?

Accepted Answer

Use them for SEO meta tags, blog post tags, YouTube tags, content optimization, academic abstract indexing or search filtering. Click any keyword or phrase to copy it instantly.

Question 4

Is my text uploaded to a server?

Accepted Answer

No. All extraction happens entirely in your browser. Your text never leaves your device and is not sent to any server.
