Every plan, and what it writes.

Planning a book is free, and credits pay for writing it. New accounts start with 50 free credits, no card needed. For more, Starter and Pro add credits every month and a credit pack adds them once. Credits never expire.

Dollars are pro rata: a plan’s price divided by its credits, times the book’s. Unused credits stay in your balance, and none of them expire.

Any paid plan includes the PDF, EPUB and DOCX of every book you write, for as long as you’re subscribed. A credit pack bought on its own adds credits for writing; bought from a book’s page, it also pays for that book’s files. The free credits write books you can read and edit in full in the app.

Extras cost more: web research adds 5 credits to a book, and regenerating a chapter costs 13 credits on a lead magnet.

What else credits pay for. Each priced before you confirm it.

Besides writing books, credits pay for these. If one fails, its credits come back automatically.

  1. Rewriting a passage with AI

    1 credit

    6 credits with web research to check it. Accepting or rejecting the result is free.

  2. Applying all comments

    1 credit a passage

    For each passage it rewrites, however many comments that passage has.

  3. Web research while writing

    +5 credits

    Added once to the book’s price, however many sources you tick. If the search finds nothing, those credits come back.

  4. Regenerating a chapter

    13–23 credits

    Priced by the book’s format: 13 credits on a lead magnet, up to 23 on a course companion.

  5. New cover art

    13–23 credits

    A fresh set of 6 cover options to choose from, at the price of regenerating one of that book’s chapters.

Free on every plan.

  • Planning a book
  • Editing it by hand
  • Restyling a cover’s type
  • Reading every chapter in the app

Coloring books, by the page. From the same credits.

A coloring book is priced by its drawn pages, from the same credits as everything else. Its plan, covers and print files cost nothing more. As with an ebook, downloading its files needs a plan, or a credit pack bought from the book’s page.

  1. Drawing a page

    3 credits

    Each page is drawn, checked and traced to clean vector line art. A page that can’t be drawn gives its credits back, and the rest of the book is still drawn.

  2. The same characters on every page

    +1 credit a page

    A page is then 4 credits. Your characters are drawn once, on a sheet for the book, and every page is drawn from it. Six of the eight styles offer it.

  3. Redrawing a page

    2 credits

    Redraw any page of a finished book, or tweak it with a note. A page that couldn’t be drawn costs its page price to try again.

Included, at no extra cost.

  • A plan for every page
  • 3 cover designs
  • The KDP interior PDF
  • The KDP cover wrap
  • Letter and A4 printables

What a coloring book comes to.

Dollars are pro rata: the lower figure is at the credit pack’s rate, $10 for 250 credits, and the higher at Starter’s, $19/mo for 300.

What a coloring book comes to at each size: its credits, plain and with the same characters on every page, and those credits in dollars, from the cheapest way of buying them to the dearest.
