Frequently Asked Questions
What is a word counter?
A word counter calculates the number of words in a piece of text, along with related statistics such as characters, letters, sentences and keyword frequency.
Does this tool check keyword density?
Yes. The Keyword Density panel lists your most frequent words and what percentage of your total word count each one makes up — useful for SEO writing and avoiding repetition.
Can I convert text case with this tool?
Yes. Use the Sentence case, Title Case, UPPERCASE or lowercase buttons above the text box to reformat your text instantly.
Can I use this tool for Urdu or other languages?
Yes. The letter counter uses Unicode-aware detection and can count letters from many different writing systems.
How is reading level calculated?
Reading level uses a Flesch-Kincaid grade estimate based on average sentence length and syllables per word. It's an approximation, not an exact grammar check.
Does the tool save my text?
Your text is processed entirely in your browser. It is only saved locally on your device (so you don't lose it on refresh) and is never sent to a server or shared with anyone.
