How it works
- Type or paste your text, or drop a .txt / .md file.
- Read the counts — they update on every keystroke.
- The most frequent words appear underneath for longer texts.
Why nothing is uploaded
Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.
Verify it yourself
- Open your browser’s developer tools (F12) and select the Network tab.
- Load your file and run the tool.
- The only requests you will see are the tool’s own code and, once cached, none at all.
Frequently asked questions
Why is the Japanese word count different from the character count?
Because Japanese is not written with spaces, so “words” are not directly countable without a morphological analyser. The unit that matters in practice — for manuscripts, forms and translation pricing — is the character, so that is what is shown, split into kanji and kana.
What is the 400-character sheet figure?
Genkō yōshi: the standard Japanese manuscript sheet of 400 squares. Publishers and universities still specify length in sheets, so the tool divides your character count by 400.
Does the text leave my browser?
No. There is no request on any keystroke — the counting is a few lines of JavaScript in this page. Paste a draft or a contract without thinking twice.
