How are words counted?

Words are sequences of characters separated by whitespace. Hyphenated compounds count as one word, which matches how most editors and publishing platforms count.

What is keyword density and why does it matter?

Keyword density is how often a word appears relative to total words. Writers use it to spot accidental repetition; SEOs use it as a rough check that a target phrase appears naturally without stuffing.

How is reading time estimated?

We use 200 words per minute for silent reading and 130 for speaking aloud - widely used averages. Dense technical text will take most people a little longer.

Is there a text length limit?

No hard limit. The counter handles book-length text comfortably since everything runs locally in your browser.

Is my text uploaded anywhere?

No. Counting happens entirely in your browser tab. Your text is never sent to a server or stored.
