Paste any text and see which words appear most often — with optional stopword filtering in Portuguese, English or Spanish.
Knowing which words appear most often in a text is useful for more things than you might expect. A writer checking for unconscious repetition, an SEO analyst looking at keyword density, a student summarizing a long article, a translator spotting the key terms before starting — all of them need a frequency count, and all of them need the option to filter out the noise. The noise is the words that appear in every text regardless of subject: articles, prepositions, pronouns, conjunctions. Linguists call them stopwords, and this tool lets you remove them with one checkbox.
The stopword lists cover Portuguese, English and Spanish, curated from the NLTK and Snowball corpora — the same lists used in natural language processing pipelines. With stopwords removed, the ranking shows the words that actually characterize the text: the nouns, verbs and adjectives that carry meaning. Without the filter, you see the raw count, which is useful when the question is not "what is this text about" but "how often does this exact word appear" — proofreading, for example, or checking whether a keyword was used too many times.
The analysis runs entirely in your browser. The text you paste is not uploaded, stored or sent anywhere, which makes the tool safe for confidential documents, drafts and unpublished content. The output shows the rank, the word, the absolute count and the percentage of the total, with a visual bar for quick scanning. You can show the top 5 or the top 500.
Common words that appear in every text regardless of subject — articles (the, a), prepositions (of, in), pronouns (he, she). Removing them reveals the words that actually characterize the text.
No. The analysis runs entirely in JavaScript on your device.
It is the count of that word divided by the total number of words after stopword filtering, multiplied by 100.
Yes. The counter works with any language. Stopword filtering is available for Portuguese, English and Spanish; for other languages, turn off the filter and the raw count still works.
Only your device memory. Texts of several thousand words analyze in under a second in modern browsers.
