Word Frequency Counter

Word frequency analysis is one of the oldest techniques in computational linguistics — counting how many times each unique word appears in a text and ranking them. The technique drives a wide range of applications: search-engine indexing (TF-IDF for relevance scoring), authorship attribution (function-word frequencies are a fingerprint), readability analysis, vocabulary learning, content auditing, and SEO keyword density checks. The catch is that without filtering, the result is dominated by stop words like "the" and "of", which carry little information. Filtering stop words and short words surfaces the content terms that actually distinguish a piece of writing. This counter runs the analysis locally with optional filters and case-insensitive matching. Need basic word and character counts instead? Use the Word Counter. Drafting content?
