Calzivo Word Counter

Calzivo Word Counter is a free online text-analysis tool for writers, students, editors and people checking the length and structure of a passage. Type or paste text into its editor to review the word count alongside sentence, paragraph, line and character metrics. The results also include a character count excluding whitespace and a rough reading-time estimate.

The word and sentence analysis uses the browser runtime's Unicode segmentation through Intl.Segmenter. It counts segments identified as word-like and can handle scripts that do not separate every word with spaces. The page explains that segmentation is a practical language-neutral model rather than the only possible definition of a word or sentence. Counts may differ with the language, context, editorial rules and Unicode data available in the runtime.

Paragraphs are treated as nonempty text blocks separated by blank or whitespace-only lines. Leading or trailing blank lines do not add paragraphs. For the line count, Windows-style and older carriage-return line endings are normalized to line feeds. Empty text has zero lines, while a trailing newline in nonempty text creates a final empty line. These definitions help users understand why different text counters can report different structural totals.

Character counting uses Unicode grapheme clusters, with a separate metric that excludes whitespace. Reading time is calculated at a rough rate of 200 words per minute: short nonempty passages are shown as under one minute, and longer estimates round upward. This is a planning guide rather than a promise about how quickly every audience will read the text.

The input limit is 200,000 UTF-16 code units. Text that exceeds the limit is not silently shortened, and the tool does not show a partial analysis as if it covered the whole entry. Users can review the displayed metrics and use the Copy analysis control to copy the analysis.

The page includes explanations, common questions and references for its counting assumptions. It is useful for reviewing drafts and comparing text structure, but it does not replace a publisher's own word-count rules or an official submission system. Where a particular count matters, check the receiving organization's definition and requirements as well.
