Benefits of the Vietnamese vocabulary analyzer

  • Accurately counts words, syllables, and characters while correctly handling Vietnamese tonal diacritics and compound words.
  • Generates a ranked word-frequency list so you can instantly spot dominant keywords or overused terms.
  • Tags parts of speech (nouns, verbs, adjectives, and more) for rapid grammatical analysis without external software.
  • Visualizes vocabulary richness, making it easy to compare the lexical diversity of different texts side by side.
  • Runs entirely in the browser — no installation, no data upload, and completely free to use.

Frequently asked questions

Does the tool fully support Vietnamese diacritics and tonal marks? Yes. The analyzer is built on UTF-8 Unicode and correctly recognizes all six tones (level, falling, rising, broken, heavy, and tumbling) as well as unique characters such as ơ, ư, and đ.

Is there a word-count limit for the input text? The tool handles typical documents of several thousand words comfortably. For very large texts, splitting the content into sections will keep results rendering quickly.

Is my text stored or sent to a server? No. All processing happens locally in your browser. Your text is never transmitted to any server or retained after you leave the page.

Can the analyzer distinguish monosyllabic words from multi-syllable compound words? Yes. The parser recognizes common Vietnamese compound words and reduplicative forms, grouping their syllables correctly rather than treating each syllable as an independent word.
