What is the Free Text Readability Analyzer?
The free Text Readability Analyzer scores your text using the Flesch Reading Ease formula and shows you the associated reading level, Avg words/sentence, Avg chars/word, and estimated Reading time. A score of 60–70 is plain English; below 30 is academic/technical. Writers, educators, and content strategists use it to match content difficulty to their audience.
- → Verify that a public-facing article is accessible to a general audience (target score 60–70).
- → Check whether educational material is appropriate for a specific grade level.
- → Simplify overly technical documentation by shortening sentences and words.
- → Compare readability before and after editing to measure improvement.
- → Audit marketing copy to ensure clarity and persuasiveness.
