Common uses

- Keeping a social media post or meta description under a character limit
- Sanity-checking the length of translated or Vietnamese-language content
Supported formats and limitations
Accepts text, up to one file at a time.
- Sentence counting is a heuristic based on `. ! ?` — like most word counters, it can't distinguish an abbreviation ("Mr. Smith") from an actual sentence end, so the count is a close estimate rather than a grammatically perfect one.
- Words are counted as runs of letters and numbers, so a string of only punctuation or emoji isn't counted as a word — matching how most word processors count.
Frequently asked questions
No. Counting happens entirely in your browser as you type — nothing is sent to a server.
Yes — word detection is Unicode-aware, recognizing Vietnamese diacritics and other non-English letters as real word characters, not just plain ASCII a-z.
No — any amount of whitespace between words is ignored; only the words themselves are counted.
By runs of text ending in ., !, or ? — a common, practical heuristic, though like any such method it can't perfectly detect abbreviations.
No fixed limit — counting stays fast even on long documents since it's a single pass over the text.
