Word Frequency Counter
Analyze word frequency in any text instantly. Count how many times each word appears with percentages. Perfect for SEO analysis, content optimization, academic research, and identifying key terms in your writing.
What is Word Frequency Counter?
The Word Frequency Counter scans text and counts how many times each word appears. It displays a frequency table sorted from most common to least common, with raw counts and percentages. You can switch between case-sensitive and case-insensitive analysis. The tool helps identify overused words, find keywords, and understand vocabulary patterns. All processing happens in the browser.
How does Word Frequency Counter work?
This tool tokenizes your text into words by splitting on whitespace and stripping punctuation. It builds a frequency map of each word, then sorts by count descending. You can filter to show the top 10, top 20, all words, or only words appearing above a threshold. The output includes the word, its count, and its percentage of total words.
