Readability Score

The Flesch Reading Ease score ranges from 0 (very difficult) to 100 (very easy). Scores of 60+ suit general audiences, 70+ are conversational, and below 30 indicates academic or legal-level prose. The ring gauge colors map directly to these bands.

The Flesch-Kincaid Grade Level translates the same math into US school grades — a score of 8.2 means an eighth-grader can understand the text. Combined with sentence-length distribution, you get a complete picture of writing complexity.
