Word count matters more than it should. Essay assignments cap you at 500 words, cover letters get skimmed if they run past a page, and Twitter/X threads or meta descriptions have hard character ceilings that reject anything over the limit. The Word Counter tallies words, characters (with and without spaces), sentences, and paragraphs the instant you type or paste text, so you can see exactly where you stand against a limit instead of guessing or counting by hand.
Paste in a draft and the counts update live as you edit — no button to press, no page reload. Alongside the raw counts, it estimates reading time based on average reading speed, which is handy for gauging how long a blog post, script, or speech will actually take an audience to get through. It also breaks down keyword density, showing which words and phrases repeat most often, which is useful for writers checking that an article isn't overusing a term and for anyone doing basic on-page SEO review before publishing.
Because everything runs client-side in your browser, nothing you paste is uploaded anywhere — draft chapters, unpublished articles, or a confidential cover letter stay on your machine. That also makes the counter fast: there's no upload wait, so you can keep it open in a tab and glance at the numbers as you write, rather than treating it as a separate step you run only at the end.
