How this service works
Split a total word count into N balanced chapters with exact per-chapter words, pages and reading minutes.
Output
Returns a structured object with: per-chapter word counts as an array, pages per chapter, reading minutes per chapter, total book reading time, base words per chapter, number of chapters that get an extra word (for remainder distribution), average words per chapter, words-per-page used, and a summary string.
Example use cases
Novel chapter planning for debut author
“I'm writing a 90,000-word novel and want to divide it into 30 chapters. Can you tell me how many words, pages, and reading minutes each chapter should be?”
Nonfiction book structure for publisher submission
“My nonfiction manuscript is 65,000 words and my editor wants 12 chapters. What's the ideal word count and page count per chapter, assuming 250 words per page?”
Reading time estimate for anthology chapters
“I have an anthology that's 45,000 words split into 18 chapters — how long will each chapter take to read, and how many pages will each one be?”
