About Word Frequency Analysis
Word frequency analysis is a fundamental technique in computational linguistics and text mining. It helps writers identify overused words, aids researchers in content analysis, and supports SEO professionals in optimizing keyword density. This tool performs all analysis client-side in your browser — your text is never uploaded to any server. It supports stopword filtering, case sensitivity control, and exports results as CSV for further analysis.

Frequently Asked Questions
How does the word frequency analyzer work?▾
It splits your text into individual words using whitespace and punctuation boundaries, then counts each word occurrence using a frequency map. Results update in real-time as you type.
What are stopwords and why filter them?▾
Stopwords are common words like "the", "is", "and" that appear frequently but carry little meaning. Filtering them reveals the most meaningful content words in your text.
Is my text sent to any server?▾
No. All analysis runs entirely in your browser using JavaScript. Your text never leaves your device.
