Word Frequency Counter This tool counts the occurrences and frequency of all words in a text and lists the results in descending order. It's very helpful for quickly understanding the main content of an article, performing keyword density analysis (for SEO), or for linguistic research.

• How Tokenization Works: The tool uses regular expressions to identify words (consecutive alphanumeric sequences) and Chinese characters. It can handle mixed Chinese and English text simultaneously.
• Case-insensitive: When checked, 'Word', 'word', and 'WORD' will be treated as the same word for counting.
• Stop Words: You can provide a list of 'stop words'. These words (usually meaningless conjunctions, pronouns, like 'the', 'a', 'is') will be ignored before counting, making the analysis focus on more meaningful keywords.
