Keyword Extractor
Quickly pull the most important keywords from any block of text. Our tool strips away common stop words, lets you set a minimum word length, and ranks words by how often they appear. Perfect for SEO research, content analysis, or understanding the main topics in a document. No signup, no uploads — everything stays private.
Why use this Keyword Extractor?
Whether you're optimizing a blog post for search engines, analyzing a competitor's content, or just curious about the most frequent terms in a document, a keyword extractor saves you from manually counting words. It filters out common words (stop words), enforces a minimum length, and sorts by frequency, giving you a clean list of what matters most.
- Stop word removal – automatically skips words like "the", "and", "is" using a built‑in English list, plus you can add custom ones.
- Adjustable word length – ignore short words (2‑5 characters) to focus on meaningful terms.
- Case‑insensitive matching – treat "Keyword" and "keyword" as the same (on by default).
- Top N filter – display only the most frequent keywords, up to 100, so you don't get overwhelmed by noise.
