Technical Details
How this word counter processes text
Counting Algorithm
This word counter uses regex-based tokenization with full Unicode support to split text into words, sentences, and paragraphs. The algorithm handles edge cases including multiple whitespace, line breaks, tabs, and mixed-language content. Word boundaries follow Unicode Text Segmentation (UAX #29) for accurate multi-language word count results.
Readability Metrics
The character counter calculates reading time based on 225 words per minute for reading (150 WPM for speaking time), rounding up with Math.ceil. Keyword density analysis identifies the top recurring words with percentage frequency, displayed with ranked badges. These metrics help writers optimize content length for SEO and audience engagement.
Character Analysis
The online word counter tracks characters with and without spaces, paragraph count, sentence count, and average word length. Real-time analysis updates on every keystroke with zero latency - all processing runs client-side in your browser. File uploads support .txt, .md, .csv, .json, .html, .xml, and .docx formats up to 10MB.
Export & Persistence
