How are syllables counted?

We estimate syllables by counting vowel groups (a, e, i, o, u, y runs) per word, with a silent-e adjustment and a minimum of one syllable per word. It’s an approximation but tracks well against reference implementations.

What does Flesch Reading Ease mean?

A score from 0–100. Higher means easier. 60+ is considered plain English (8th–9th grade). 30 or below is college-graduate level.

What does Flesch-Kincaid Grade Level mean?

An approximate U.S. school grade level needed to understand the text. A score of 8 means an 8th grader could read it.

What counts as a “complex word”?

A word with three or more syllables that isn’t just a plural or inflected form of a shorter word (e.g. “computing” doesn’t count because “compute” is shorter, but “computer” does).
