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.

Does this word counter work offline?

Once the page loads, yes! All processing happens in your browser using JavaScript, so you can continue counting words even if your internet connection drops. However, you'll need an internet connection to initially load the page and its resources.

What file formats can I upload?

Currently, we support .txt (plain text) and .docx (Microsoft Word) files. Click the "Upload File" button to import your document directly. The text will be extracted and displayed in the editor for instant analysis. PDF support may be added in future updates.

How is reading time calculated?

Reading time is calculated based on the average reading speed of 200-250 words per minute. This is a standard metric used across the publishing industry. Actual reading time may vary based on content complexity, reader's familiarity with the subject, and individual reading speed.

Is there a word limit for analysis?

There is no strict word limit! Our tool can handle very large documents. However, extremely long texts (100,000+ words) may slow down performance on older devices since all processing happens in your browser. For best performance, we recommend analyzing documents under 50,000 words.

Can I use this tool for commercial purposes?

Yes, absolutely! Our word counter is completely free for both personal and commercial use. Use it for client projects, professional writing, business content, SEO work, or any other purpose. No attribution required, though we always appreciate it when users share our tool with others.
