Question 1

What is the 5-7-5 rule for haiku?

Accepted Answer

A traditional English-language haiku has three lines with a syllable count of 5, then 7, then 5 — for a total of 17 syllables. The form also favors a seasonal reference (kigo) and a juxtaposed image (kireji). Outside Japan many modern haiku relax the strict 5-7-5 rule, but the syllable pattern remains the most widely taught starting point.

Question 2

How does the syllable counter work?

Accepted Answer

The tool applies a heuristic English syllable-counting algorithm based on vowel groups and common-suffix rules. It runs locally in your browser and refreshes on every keystroke. Most common words are counted correctly, but unusual loanwords or dialect forms (for example fire or hour) may sometimes need a manual check.

Question 3

Is my poem uploaded to a server?

Accepted Answer

No. The haiku checker is fully client-side. Your lines are counted in the browser and nothing leaves your device, so it is safe to paste unpublished drafts.
