Reading Level Analyzer

Summary

Paste any text to instantly see its grade level from four readability formulas: Flesch-Kincaid, Flesch Reading Ease, Gunning Fog, and SMOG.

How it works

1. Paste or type your text into the input area on the left.
2. The tool automatically counts sentences, words, syllables, and complex words.
3. Four readability formulas run in real time and display grade-level scores.
4. A color-coded badge shows whether the text is easy, moderate, or difficult.
5. Use the summary panel to compare all four scores side by side.
6. Review the word and sentence statistics to pinpoint what drives the score.
