Tool Introduction
The online word frequency tool can tokenize any text and calculate word frequencies, helping you quickly identify high-frequency words, key concepts, and repeated content. It is widely used in text analysis, SEO keyword mining, paper writing plagiarism checks, public opinion monitoring, and open-ended survey question analysis.
Statistics Options
Ignore case—treat "Apple" and "apple" as the same word; remove stop words—filter out high-frequency function words with little meaning such as "的、了、和、是、the、a、is"; split Chinese by character—count Chinese by individual characters (when disabled, Chinese phrases are split by spaces or punctuation); minimum word length—filter out words shorter than the specified value to avoid single-letter noise.
Privacy and Security
This tool runs entirely locally in your browser. All tokenization and statistics logic is handled by front-end JavaScript, and none of your text content is uploaded to a server. You can safely process sensitive business documents, user comments, or internal materials.
Tips
It is recommended to first enable "Ignore case" and "Remove stop words", then enable "Split Chinese by character" to get the cleanest keyword list. If you need to analyze Chinese phrases, disable "Split Chinese by character", and Chinese will be split by spaces or punctuation. Click a table row to highlight the distribution of that word in the text.
