Frequently asked questions

Is Keyword Density Analyzer free to use?

Yes. Keyword Density Analyzer is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.

Does Keyword Density Analyzer upload your text to a server?

No. Keyword Density Analyzer processes your text inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.

Is there a limit on how much input I can use?

Keyword Density Analyzer handles inputs into the megabytes without trouble; the only real limit is how much your browser tab can hold in memory.

Do I need to install anything to use Keyword Density Analyzer?

No installation is needed. Keyword Density Analyzer runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.

Can I use Keyword Density Analyzer on a phone or tablet?

Yes. The Keyword Density Analyzer interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.

What happens to your text when I close the tab?

It is discarded. Keyword Density Analyzer keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
