Readability scores

Paste some text on the left and tap Check Readability to see scores and stats.

Scores are approximations based on automated syllable and sentence counting and are best used as a general guide, not a precise linguistic evaluation.
How to interpret the scores
  • Flesch Reading Ease: 90–100 = very easy; 60–70 = plain English; 0–30 = very difficult.
  • Flesch–Kincaid Grade Level: Approximate U.S. school grade needed to understand the text.
  • Reading time: Rough estimate assuming steady reading at your chosen words-per-minute value.

Short paragraphs, simpler sentences, and everyday vocabulary usually improve readability. Use this tool as a quick check while editing articles, emails, landing pages, or documentation.
