Word Counter

About Word Counter

The Run It Free Advanced Word & Text Analyzer is a comprehensive, privacy-first writing tool designed for content creators, SEO copywriters, students, authors, and digital marketers. Unlike basic word counters that only count characters, our analyzer provides deep real-time text insights. Compute instant word, character, sentence, and paragraph totals; audit text readability across 5 recognized formulas (including Flesch Reading Ease and Flesch-Kincaid Grade Level); inspect 1-word, 2-word, and 3-word n-gram keyword densities; verify social media character limits for Twitter/X, LinkedIn, Instagram, and SEO tags; and clean formatting with one click. Everything processes 100% locally in your web browser with zero server uploads.

Common Problems & Solutions

My posts get cut off on social media or search engine results.

My writing feels too complex or difficult for general readers.

Check your Flesch Reading Ease and Flesch-Kincaid Grade Level in real time, then shorten long sentences and simplify complex vocabulary.

Am I accidentally keyword stuffing my blog post?

Use the N-Gram Keyword Density tool to audit 1-word, 2-word, and 3-word frequencies and keep keyword density within healthy 1–3% limits.

Pro Tips & Best Practices

• Aim for Grade 7–8 for Web Content: Most successful blog posts and online articles perform best when written at a 7th to 8th-grade reading level.
• Check 2-Word & 3-Word Phrases: Single keywords can be misleading; auditing 2-word and 3-word n-grams gives a much truer picture of your topic coverage.
• Set Incremental Word Goals: Break large writing tasks (essays, blog posts) into manageable milestones using our Target Word Count Goal progress ring.

Frequently Asked Questions

How does the word counter count words?

The analyzer splits your text by whitespace sequences and punctuation boundaries, ensuring accurate word counts across hyphenated words, line breaks, and multi-paragraph documents.

How is the Flesch-Kincaid Readability score calculated?

Flesch-Kincaid Grade Level uses sentence length (words per sentence) and syllable density (syllables per word) to estimate the US school grade level required to understand the text.

What is keyword density and why does it matter?

Keyword density measures how frequently a word or phrase appears relative to total words. Maintaining a healthy keyword density (1–3%) helps search engines understand your topic without over-optimizing.

How are reading and speaking times estimated?

Reading time is calculated at an average silent reading speed of 200 words per minute (WPM), speaking time at 130 WPM, and handwriting speed at 19 WPM.

Is this tool free and safe for private documents?

Yes, 100% free with no sign-up or usage limits. Because all processing happens client-side in your web browser, your documents are never uploaded to any server.
