What is a good keyword density?

There's no strict rule, but 1-2% is a common guideline to avoid keyword stuffing while keeping content natural.

Does it support multi-word phrases?

Yes, you can analyze density for 1-word, 2-word, and 3-word phrases (n-grams).

Are stop words excluded?

Yes, common stop words like 'the' and 'and' are filtered out by default so results focus on meaningful terms.

Is my data uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your input never leaves your device and nothing is logged or stored on our servers.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.
