Frequently Asked Questions

How accurate is this word counter?

Our word counter is 100% accurate and uses standard word counting algorithms. It counts words separated by spaces, following the same rules as Microsoft Word and Google Docs. Numbers, hyphenated words, and contractions are counted as single words.

How does the AI text detector work?

Our AI detector analyzes patterns common in AI-generated text: uniform sentence length, repetitive structures, and limited vocabulary diversity. It's a heuristic tool providing probability estimates, not definitive proof. Human-written text with consistent patterns may score higher, while edited AI text may score lower.

What is keyword density and why does it matter for SEO?

Keyword density is the percentage of times a keyword appears in your text compared to total words. For SEO, the ideal density is 1-3%. Too high (keyword stuffing) can hurt rankings, while too low may miss optimization opportunities. Our tool helps you find the perfect balance.

Can I upload Word documents (.docx) for word counting?

Yes! Click the "Upload File" button to import .txt or .docx files directly. Your document will be processed instantly, and all text will appear in the editor for analysis. Your files are processed locally in your browser and are never uploaded to our servers.

Is my text data safe and private?

Absolutely! All text analysis happens directly in your browser using JavaScript. Nothing is sent to our servers, and no text data is stored. When you close the page, your text is gone. This ensures complete privacy and security for your sensitive documents.
