Readability checker
Flesch score, grade level, and every hard sentence, adverb, passive, filler and repeated word highlighted as you type. No length limit — paste a whole manuscript.

Spine width calculator
How thick your book will be, from its page count and paper stock — and the full cover size including bleed, which is the file your designer actually needs.
