How is the estimated reading time calculated?

Reading time is based on the industry standard average reading speed of 200 words per minute (WPM), while speaking time is calculated at 130 WPM.

Is my pasted text saved on your servers?

No. The word counter operates 100% locally in your browser. None of your text is ever uploaded or transmitted across the network.

What is keyword density?

Keyword density shows the percentage of times a word appears compared to the total number of words in your text, helping optimize content for SEO without keyword stuffing.

Does LutaTech save or transmit my written text?

No. All word counting and text analysis algorithms execute entirely on your device inside your web browser. Your text never leaves your computer and is never sent to any server.

What is the difference between characters with and without spaces?

Characters with spaces count every single keystroke including spaces, tabs, and line breaks. Characters without spaces only count alphanumeric letters, digits, and punctuation marks, which is often required for academic submissions and character-restricted platforms like Twitter/X or SMS.

Can I use this word counter offline?

Yes! Once the page is loaded, the word counter runs entirely through client-side JavaScript, meaning it continues functioning seamlessly even without an active internet connection.
