Syllable Counter

Syllable Counter Online is a free, browser-based syllable analysis tool for writers, poets, songwriters, students, and educators. Count syllables instantly in individual words, sentences, lyrics, or complete poems, with real-time totals and detailed line-by-line analysis. Key features include: 1. Dictionary-backed counting: Every word is checked against a 126,044-word CMU Pronouncing Dictionary for reliable syllable counts. 2. Visible syllable breakdowns: Words are automatically split into syllable parts, so you can see how each count is calculated. 3. Poetry form checking: Built-in support for Haiku (5-7-5), Tanka (5-7-5-7-7), Cinquain (2-4-6-8-2), Limerick, and Iambic Pentameter, with each line compared against its target. 4. Custom patterns: Create your own syllable pattern for poems and other structured writing. 5. Estimated counts made clear: Words not found in the dictionary are counted using spelling rules and clearly marked as estimated rather than presented as exact. 6. Spelling assistance: Possible misspellings are highlighted with suggested corrections and their corresponding syllable counts. 7. Writing and readability insights: See word, character, sentence, and line counts, plus syllables per word and sentence and word-length distribution. 8. Export and sharing: Copy reports, create share links, or export your results directly from the browser. 9. Privacy-first by design: Text processing happens locally in your browser. Your writing is not uploaded to a server, and no account or installation is required. The result is more than a basic syllable counter: it helps you understand why a word has a particular count, identify exactly which line is too long or too short, correct uncertain words, and refine your writing without repeatedly counting by hand.
