Clean

Paste a picture-book manuscript page by page and the browser counts what a reading teacher would: words and sentences per page, the revised Spache grade, Flesch-Kincaid, New Dale-Chall, Dolch sight-word coverage, the rhyme scheme and rhythm of every page, refrains and page turns - free, before you sign in. Then a reading teacher levels the manuscript against the age you are writing for (ages 2-3, 3-5, 5-7 or 7-9), naming the words a child would stumble on and the phonics the pages teach, or revises every page to that level while keeping your story, and the browser re-levels the revision. Derived from the agent skills @jamesrochabrun/kids-book-writer and @jamesrochabrun/reading-teacher (github.com/jamesrochabrun/skills).
