Syllable Counter

It uses a vowel-group heuristic — grouping adjacent vowels, dropping most silent trailing 'e's, and handling common endings — which is right for the large majority of everyday words. English spelling is irregular, so some words with silent letters, unusual endings, or names may be off by one. Treat it as a strong estimate.

In haiku mode, put each line of your poem on its own row. The tool counts the syllables in each of the first three lines and compares them to the traditional 5, 7, 5 pattern, marking each line as correct or not and telling you when the whole poem fits.

Most disagreements come from words that a heuristic can't nail — silent 'e' that's actually pronounced (like in some names), regional pronunciation differences, or unusual spellings. For a definitive answer on a tricky word, check a dictionary, which lists the syllable breakdown.
