About

Five panels over one text box: overview, words and keywords, sentences, readability and clean up. Everything is recomputed as you type, on this device.

Words are segmented, not split on spaces. Counting with a regular expression gets Chinese, Japanese and Thai wrong, and mangles hyphenated and apostrophised words in European languages. This uses the browser Intl segmenter and rejoins hyphenated forms, so "state-of-the-art" is one word and a line of Japanese has a real word count rather than a character count.

Readability is language-specific, or it is not offered. Flesch Reading Ease was fitted to English and means nothing applied to Polish. So the page offers the six English measures for English, FOG-PL for Polish, Wiener Sachtextformel for German, Flesch-Douma for Dutch, Kandel-Moles for French, Fernandez Huerta for Spanish and Indice Gulpease for Italian - and LIX, which is a European measure rather than an English one, for everything. No score is shown below 100 words, because none of these formulas means anything on a sentence.

There is no AI detection and no plagiarism check here, because neither can be done honestly in a browser, and a confident wrong answer about either does real damage to a real person.

02 / Use case

What it solves

The problem
  • Word counters split on spaces and give a nonsense number for Chinese, Japanese or Thai.
  • Readability tools report a Flesch score for a Polish text, where it means nothing.
  • Keyword density is dominated by "the" and "and" unless stop words are removed.
The outcome
  • Proper word segmentation, so hyphenated words and non-spaced scripts both count correctly.
  • Readability formulas chosen for the language, and none shown when the text is too short to mean anything.
  • Keyword density with a real stop-word list for each of the ten interface languages.
Who it is for
  • Writers and editors checking length, pace and reading level.
  • Anyone writing to a word or character limit.
  • People writing in more than one language who need the right measure for each.
03 / Key Features

Key Features

The most important capabilities, explained in practical terms.

Counts That Are Correct

Words, characters with and without spaces, sentences, paragraphs, unique words and reading time - segmented with the browser Intl segmenter rather than split on whitespace.

Keywords, Stop Words Removed

One-, two- and three-word phrases ranked by frequency and density, with a stop-word list for each of the ten interface languages so the results are about the subject.

Sentence Analysis

Length distribution, the longest sentences called out, and the average - the numbers behind "this reads as heavy" rather than the impression.

Thirteen Readability Measures

Six English formulas plus FOG-PL, Wiener Sachtextformel, Flesch-Douma, Kandel-Moles, Fernandez Huerta and Indice Gulpease, and LIX for every language. Nothing is scored below 100 words.

Clean Up

Collapse whitespace, normalise quotes and dashes, strip HTML, change case and remove empty lines, with the result shown before you copy it.

Five Direct Routes

Word counter, character counter, keyword density checker, readability checker and case converter each have their own page opening on that panel.

The hard sentences, marked

A distribution says a fifth of your sentences are long; the text itself says which ones. Every sentence is shaded by length, in the same bands the chart counts, so the rewrite has somewhere to start.

One draft against another

Pin a version, rewrite it, and the word count, sentence count, average sentence length and lexical diversity stand side by side with the change between them. Editing is a before-and-after job, and this is the after.

A target, and a draft that survives the tab

Set a length in words or characters and watch the progress towards it. What is in the box is kept in your browser, so a closed tab is not a lost paragraph, and the word and phrase tables leave as a CSV.
