Why This Text Analyzer Is Different
Most tools make you wait, sign up, or trust your data with a server. This one starts working the moment you open the page.
This is a utility-first experience: use the powerful analyzer above, then learn how it works below.
🔐 Zero Data Exposure

⚡ Instant Feedback

🌐 One File, Full Power
No installation. No internet required after loading. Use it anywhere.
🔍 How It Works
Built with pure HTML, CSS, and JavaScript — no frameworks, no external libraries.
Syllable Estimation
Uses vowel clustering and silent ‘e’ rules for accurate readability scoring:
word = word.toLowerCase().replace(/[^a-z]/g, ”);
if (word.length <= 3) return 1;
let count = 0;
const vowels = ‘aeiouy’;
if (vowels.includes(word[0])) count++;
for (let i = 1; i < word.length; i++) {
if (vowels.includes(word[i]) && !vowels.includes(word[i-1])) count++;
}
if (word.endsWith(‘e’)) count–;
return Math.max(1, count);
}
