Count words, characters, and sentences in real time. Analyze readability, estimate AI tokens, track keyword density, and get writing insights — all processed locally in your browser.
Real-time text analysis & readability engine
A word counter is an indispensable utility that counts words, characters, sentences, and paragraphs in any given text. Modern word counters go far beyond basic counting — analyzing readability formulas, estimating AI token usage (GPT-4 / Claude), and tracking keyword frequency.
Our tool operates 100% in your browser. Your text never touches any external server, guaranteeing complete privacy for academic papers, legal documents, client work, and personal writing.
High-performance single-pass tokenization
Accurate word counting requires handling edge cases like multiple spaces, tabs, line breaks, Unicode emojis, hyphenated compound words, contractions, and punctuation boundaries.
Our engine uses a single-pass tokenization algorithm capable of processing over 1 million characters without lag, delivering instant real-time statistics as you type or paste.

|---|---|---|---|
| Short / News Snippet | Under 300 words | Thin content — quick news updates or product descriptions | Low SEO |
| Standard Blog Post | 600 - 1,500 words | Suitable for general articles, how-to guides, and Q&A posts | Good |
| Long-Form Article | 1,500 - 2,500 words | Ideal for competitive keywords, in-depth tutorials, & guides | High SEO |
| Pillar Content | 2,500 - 5,000 words | Authority hub pieces covering broad industry topics | Very High |
| Ultimate Guide | 5,000+ words | Exhaustive documentation requiring Table of Contents & visual breaks | Maximum |

Understanding Flesch-Kincaid, Gunning Fog, and readability grade levels
Readability metrics compute sentence length, syllable counts, and character ratios to measure comprehension difficulty:
| Readability Metric | Score Range | Target Audience Level | Best Used For |
|---|---|---|---|
| Flesch Reading Ease | 0 - 100 | 60-70 (Standard Adult) | Web content, blogs, & public articles |
| Flesch-Kincaid Grade | Grade 1 - 18 | Grade 7 - 8 (General Web) | K-12 & commercial publishing |
| Gunning Fog Index | Grade 6 - 20 | Below 8 (Broad Access) | Business writing & journalism |
| SMOG Index | Grade 4 - 18 | Grade 6 - 8 (Consumer) | Healthcare, medical, & government text |
| Coleman-Liau Index | Grade 1 - 16 | Grade 7 - 9 | Short text without syllable counting |
Understanding LLM tokens for OpenAI GPT-4, Claude, & Gemini
Large Language Models process text in subword units called tokens. In English text, 1 token is roughly 4 characters or ~0.75 words.
• GPT-4o Context Limit: 128,000 tokens (~96,000 words)
• Claude 3.5 Sonnet: 200,000 tokens (~150,000 words)
• Gemini 1.5 Pro: 1,000,000+ tokens (~750,000 words)
Zero server tracking, zero data retention
Your text is processed entirely in your browser memory. No text is ever uploaded to any external server, cloud database, or third-party analytics.
Common questions about word counting, reading speed, and privacy
The tool splits your text by whitespace boundaries and counts each token as a word. It processes everything in real-time directly in your browser — no server calls are made.
Yes. The counter handles Unicode, accented characters, and multibyte scripts. However, languages without whitespace word boundaries (Chinese, Japanese, Thai) may report character-level counts differently than word counts.
Sentences are detected by terminal punctuation marks (period, question mark, exclamation mark). Abbreviations like 'Dr.', 'Mr.', and 'U.S.' are handled to avoid false splits.
It measures readability on a 0-100 scale. Higher scores mean easier text. A score of 60-70 is considered standard for adult readers. It uses average sentence length and syllables per word.
It translates readability into a US school grade level. A score of 8 means an 8th grader can understand the text. Most web content should target grades 6-8.
Token estimation uses character-per-token ratios specific to each model family. GPT models average ~4 characters per token, while Claude averages ~3.5. These are estimates — actual tokenization depends on vocabulary.
Vocabulary richness (also called Type-Token Ratio) is the number of unique words divided by total words. A higher ratio indicates more diverse vocabulary. Academic writing typically has a ratio of 0.4-0.6.
Reading time is based on an average reading speed of 238 words per minute (adult average from research). Speaking time uses 130 WPM, and skimming uses 400 WPM.
N-grams are consecutive word sequences. Bigrams are 2-word phrases, trigrams are 3-word phrases. They help identify repeated phrases and keyword patterns useful for SEO analysis.
Keyword density is the percentage of times a keyword appears relative to total words. SEO best practice recommends 1-2% density. Above 3% may be flagged as keyword stuffing.
Emojis are detected using Unicode ranges and counted separately. They are not counted as words but are included in the character count.
Invisible characters include zero-width spaces, zero-width joiners, soft hyphens, and other non-printing Unicode characters that can cause issues in text processing.
No. All processing happens 100% in your browser using JavaScript. Your text never leaves your device. Nothing is uploaded, stored, or shared with any server.
Yes. The tool is optimized for documents up to 1 million+ characters. It uses efficient single-pass algorithms and memoized computations to maintain responsiveness.
The Gunning Fog Index estimates years of formal education needed to understand text. It considers average sentence length and percentage of complex words (3+ syllables). Ideal score: 7-8 for broad audiences.
SMOG (Simple Measure of Gobbledygook) predicts the grade level needed to understand text. It counts polysyllabic words in a sample of 30 sentences. Most accurate for healthcare and government documents.
Unlike syllable-based formulas, Coleman-Liau uses character counts and sentence counts. It is reliable for short texts where syllable counting may be inaccurate.
Page count is estimated at 250 words per page, which is the standard for double-spaced, 12pt font documents (academic standard). Actual page count depends on formatting.
Stop words are common function words (the, is, at, which, on, etc.) that carry little meaning. The word frequency analyzer can filter these out to show more meaningful content words.
Each platform has character limits for posts. The tool shows how much of each platform's limit your text uses: X (280 chars), LinkedIn (3000), Facebook (63,206), Instagram (2200), and more.
The tool identifies common passive voice patterns (e.g., 'was written', 'is being made'). It uses pattern matching rather than full grammar parsing, so some complex passives may be missed.
Yes. You can export your full analysis as a TXT report, CSV data, or JSON. You can also copy individual statistics or the complete word frequency table.
Characters include everything: letters, numbers, spaces, punctuation, symbols, and emojis. Letters only count alphabetic characters (a-z, A-Z, and Unicode letters).
Hyphenated words separated by spaces are counted as separate words. Hyphenated compounds without spaces (e.g., 'well-known') are counted as one word.
Writing insights are automated suggestions based on your text analysis: long sentences, short paragraphs, passive voice overuse, keyword stuffing, and sentence length variance.
The syllable counter uses a rule-based English heuristic that handles most common words correctly. It may occasionally miscount unusual words, borrowed terms, or proper nouns.
Research suggests 1,500-2,500 words for competitive topics. However, quality matters more than length. The tool classifies content as thin (<300), short (300-600), optimal (600-2500), or long-form (2500+).
Yes. The tool helps ensure you meet word count requirements, monitors readability for your target audience, and identifies potential style issues before submission.
