Level a picture book, page by page

Paste your manuscript with a blank line between pages. Your browser counts what a reading teacher would: words and sentences per page, the Spache and Flesch-Kincaid grades, Dolch sight words, the rhyme scheme and rhythm of every page, refrains and page turns — free, before you sign in. Then a reading teacher levels it against the age you are writing for, or revises it to that level while keeping your story.

Each example ships with a saved model run, so you can see a whole level report and a whole revision — including the reconciliation — without signing in and without spending a credit.

The brief — who the book is for, what you want checked or changed nothing written yet

The manuscript — a blank line, a line of dashes or "Page 3" between pages nothing pasted yet

Drag a .txt or .md in, or Everything is read in your browser. Nothing uploads until you run. A personalised book? A first name is all the story needs - leave out a real child's surname, school, address or birthday.

Reconciliation with the engine

Every number the teacher wrote was re-read against the figures the browser computed, every word they flagged or taught was looked for on the page, and in the revise lane every page was checked for revised text. A disagreement here means the prose, not the arithmetic, is wrong.

What this does, and what it does not

The numbers are each formula's definition, applied as written: the revised Spache grade is 0.121 × words per sentence + 0.082 × the percentage of word types not on Spache's familiar list + 0.659 (Spache 1974; regular inflections, proper nouns and numerals count as familiar); Flesch reading ease is 206.835 − 1.015 × words per sentence − 84.6 × syllables per word (Flesch 1948); the Flesch-Kincaid grade is 0.39 × words per sentence + 11.8 × syllables per word − 15.59 (Kincaid 1975); the New Dale-Chall raw score is 0.1579 × the percentage of words not on the 3,000-word list + 0.0496 × words per sentence, plus 3.6365 when that percentage is over 5 (Chall and Dale 1995); Dolch coverage is the share of words on Dolch's 220 service words (Dolch 1936). Syllables and rhymes come from the CMU Pronouncing Dictionary. A sentence ends at a full stop, a question mark or an exclamation mark — not at a line break or an ellipsis, which in a picture book is a page-turn cue.

A grade measures what a child can decode alone; a picture book is read aloud to a child two to four years younger than its grade implies, which is why a Spache grade of 2 is at home in a book for four-year-olds. The word, page and grade ceilings per age are the desk's own trade guidance, not a rule. Every figure the teacher then writes is re-read against this engine, and the page shows you where the two disagree. It does not judge whether a story is good.
