What other generators do
Most LLMs predict tokens, not syllables. Ask for a haiku and you'll often get 6-8-5 or 4-6-7 — the model can't hear the phonetics, so it bluffs.

Note · Our generator enforces the 5-7-5 syllable count via the CMU Pronouncing Dictionary. Kigo and kireji are advisory — flagged in the checklist but not auto-rejected.
Tradition
Originally the opening stanza (hokku) of a longer collaborative renga, the haiku separated into a standalone form in 17th-century Japan through Bashō, who grounded it in seasonal observation and the cut between images.
Modern English haiku often play loose with the 5-7-5 count — partly because English syllables differ from Japanese on (phonetic units). When you want strict form, you want a tool that counts.
