Check keyword density
Not because word frequency helps rankings — it has not for years — but because seeing the top twenty words of a page tells you in five seconds whether it is really about what you thought.

How it works
- Paste the text, or the whole HTML (tags are stripped).
- Set the minimum word length and whether to ignore common words.
- Read the table.
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 fetch the tool’s own code — and, for a few heavy tools, their open-source engine from a public CDN — plus one small page-view ping to loreatec.jp (page address and title, nothing more). None of them carry your file.
Frequently asked questions
What density should I aim for?
None. Writing towards a percentage makes text worse and has not helped rankings since the early 2010s. Use the table diagnostically: if a page about warehouse logistics has “contact” as its top word, the problem is not the density, it is the page.
Does anything leave my browser?
No. Nothing is sent to a server. The whole tool is a small program that runs inside your browser tab. Once the page has loaded, it keeps working even with the internet switched off.
