How the Word Frequency Counter works
The Word Frequency Counter takes Text and returns the answer instantly — no button to hunt for, no page reload. Writers use the top-10 list to catch their own crutches — the same adverb appearing twenty times. A diversity above 0.45 reads rich; below 0.25 the text leans on repetition, which is fine for SEO copy and bad for essays.
Enter your own numbers to replace the example values; the result panel updates as you type. Everything runs in this single page, so nothing you enter leaves your device.
