What counts as a word?
A word is any string of characters separated from the next by whitespace. Hyphenated compounds ("state-of-the-art") and contractions ("don't") each count as one — the same rule Microsoft Word and Google Docs apply. Numbers, URLs, and standalone punctuation count too, which is why a paste that includes timestamps or links may show a slightly higher word count than you expect.
Who uses a word counter?
- Students — hitting essay limits without trimming the wrong ideas.
- SEO writers — keeping titles 50-60 chars, meta descriptions under 160, and tracking keyword density.
- Bloggers and journalists — sizing drafts and tracking reading time.
- Authors — daily word-count goals and chapter length checks.
- Speakers — converting word count to speaking time before rehearsal.
- Developers — counting lines and characters in code snippets and log files.
Frequently asked questions
- How does an online word counter work?
- It splits your text on whitespace and counts the resulting tokens. Our counter does this entirely in your browser using JavaScript — there's no upload, no server round trip, and the count updates as you type.
- What counts as a 'word'?
- Any sequence of characters separated by whitespace. Hyphenated terms like 'state-of-the-art' count as one word; contractions like 'don't' also count as one. This matches how Microsoft Word and Google Docs report word count.
- Is there a character or word limit?
- No. Paste a tweet or a 200,000-word novel — the tool runs locally so it scales to whatever your browser can hold in memory.
- Is my text stored or sent anywhere?
- No. Everything happens in your browser. We only keep a copy in your own localStorage so the text survives a refresh; clear it any time with the Clear button.
- Can I use it offline?
- After the first visit, yes. The page is cached by your browser and the counter has no server dependency, so it keeps working without a connection.
