FAQ

How does it count syllables?

Heuristic: count vowel groups, subtract silent-e at word end, adjust for known prefixes/suffixes. Works on English; not a dictionary lookup.

What's the accuracy?

~90% on common words, lower on technical/foreign terms. Compounds ('greenhouse', 'daytime') are the main failure mode. For perfect accuracy, use a pronunciation dictionary.

Why does this matter for slugs?

Short, syllable-aware slugs are more memorable and pronouncable. Tools use this count to score 'brandability' of name candidates.

Is it useful for poetry?

Meter analysis, yes — count syllables per line to check iambic pentameter or haiku structure. The heuristic is good enough for verse checking.
