How the Readability Checker works

This tool analyses your text in real time using clear, consistent rules for counting words, characters, sentences and paragraphs, and for transformations such as case conversion and cleaning. Where readability is measured, it uses established formulas such as Flesch reading ease. All processing happens in your browser as you type, so nothing you write is uploaded.

Tips & best practices

• For general web content, aim for a reading level around grade 8-9 so most people can follow it easily.
• Shorten long sentences and swap complex words for simple ones to raise the reading-ease score.
• Read your text aloud — if you run out of breath in a sentence, it is too long.

Standards & accuracy

Provides accurate, real-time text analysis using consistent, transparent counting rules.

Counts follow consistent, transparent rules. Different platforms occasionally count characters slightly differently (for example, how they treat emoji), so check against your target platform for hard limits.
