Frequently asked questions (Word Counter)
Is this word counter really free?
Yes, completely free. No premium tiers, no hidden fees, no watermarks. Analyze as much text as you need, entirely within your browser.
What is lexical density?
Lexical density measures the proportion of unique words (types) to total words (tokens) in a text. A higher lexical density indicates richer vocabulary and more complex content. It's calculated as: (Number of Unique Words ÷ Total Words) × 100.
What are readability scores?
Readability scores estimate how easy or difficult a text is to read. The Flesch Reading Ease score ranges from 0–100 (higher = easier). The Flesch-Kincaid Grade Level estimates the US school grade level needed to understand the text.
What is keyword density?
Keyword density is the percentage of times a specific keyword appears in your text relative to the total word count. It's calculated as: (Keyword Count ÷ Total Words) × 100. This is important for SEO optimization.
Does it handle large text files?
Yes, the tool can handle large documents. Performance depends on your device's memory and browser, but most documents (up to a few MB) analyze instantly.
Is my text data secure and private?
Yes. All processing happens entirely within your browser; no text is sent to any server, making it safe for sensitive documents, drafts, and proprietary content.
Can I export the analysis results?
Yes! You can copy the results to your clipboard or export them as CSV, TXT, or JSON for further analysis or documentation.
What languages does it support?
The tool supports all languages that use the Latin alphabet (English, French, Spanish, German, etc.). It also supports Unicode characters, so it works with non-Latin scripts as well.
