Analyze text for sentence length, paragraph count, reading time, syllable count, and vocabulary level.
Paste or type text into the box and the dashboard recalculates as you go: sentence count, average words per sentence, paragraph count, estimated reading time, average syllables per word, and a vocabulary/reading-level estimate. Everything runs on the words as typed, so pasted HTML tags, footnote markers, or stray line breaks get counted as text and skew every downstream number. The figure people misread most is reading time - it is a fixed words-per-minute estimate applied to your word count, not a measurement of how fast any particular reader will actually get through the piece.
The tool splits text into sentences on end punctuation (period, question mark, exclamation point), counts words between splits, and treats blank-line breaks as paragraph boundaries. Average sentence length is total words divided by sentence count. Because splitting is punctuation-based, abbreviations like 'Dr.' or decimal numbers can be misread as sentence breaks and inflate the sentence count.
Each word's syllables are estimated by counting vowel-sound groups rather than by dictionary lookup, since a client-side tool has no pronunciation database to check against. Average syllables per word and average sentence length then feed a standard readability formula to produce a grade-level or difficulty estimate, so the score is only as accurate as the syllable heuristic behind it.
No. It multiplies your word count by a fixed average reading speed, the same assumption for every piece of text. It does not know your reading speed, whether the text is technical or skimmable, or whether the reader will pause to reread parts, so treat it as a rough estimate rather than a personalized measurement.
No. It is an estimate produced by a readability formula that uses average sentence length and average syllables per word as inputs. It is not a certified reading-level assessment and can disagree with other readability tools that use a different formula or a different syllable-counting method.
