Choose what you want to make, pick the details, and Rank Fuel builds the inside pages and matching cover for you.
No copying the same page 110 times. No wrestling with margins. No separate cover calculation. Just a much shorter route from “I could make that” to a book you can review and upload to KDP.
Pick the page style and size. Rank Fuel turns it into a complete book, so you can spend your time on the cover idea, title and niche instead of duplicating pages.
Start with a useful daily structure instead of a blank page. Rank Fuel repeats it neatly through the book and builds the matching cover around the finished edition.
A notebook is simple to use. It is tedious to build. A puzzle book is fun to solve. It is not fun to assemble puzzle by puzzle, answer by answer, page by page. Content Studio takes care of the production work that gets between the idea and the finished book.
Choose the format once. Rank Fuel repeats it consistently through the book.
The cover is created for the generated edition instead of being treated as a separate maths problem.
A quicker build means it is easier to test a new format, audience or book concept.
Spend more time on the idea, niche, title and positioning, and less on repetitive layout work.
No publishing jargon. No “content type” decision tree. Pick the book and start making it.
Make lined journals, college-ruled notebooks, dot grids or squared books without building hundreds of repeat pages yourself. Add one-liners on Pro when you want every page to have a little more personality.
Pick a subject and turn it into a whole book. Rank Fuel creates the puzzles, matches the solutions, builds the contents and lays out the pages so you are not stitching the book together one puzzle at a time.
These book types are not live yet, but they show where Content Studio is going: more useful books you can build without turning the production into a project of its own.
Give people a simple place to tick off the habits they are trying to build. Choose the structure once and let Rank Fuel repeat it through the year.
Build an undated planner with room for the week, priorities and notes, without having to draw and duplicate every spread yourself.
Give readers a page for the title, author, dates, rating and what they thought, then turn that useful little routine into a complete book.
Choose a topic and build a complete quiz book with questions, answer choices and a matching answer section, instead of writing and laying out every question one by one.
Build books full of deduction puzzles with clue sets, solving grids and answer pages, so the challenge is in solving them rather than in producing every puzzle by hand.
Build an A–Z keeper with repeatable spaces for sites, usernames and notes, without constructing the alphabetical layout from scratch.
Generate solvable puzzles and matching answers in different difficulty levels, then let Rank Fuel turn them into a book instead of making every grid yourself.
Create mazes at different difficulty levels and add the answer routes automatically, without drawing or checking every puzzle by hand.
Turn a word set into interlocking puzzles with clues and completed answer grids, then build the whole book without piecing the pages together manually.
Create substitution ciphers with a starter hint and matching solutions, then assemble them into a book without encoding every quotation yourself.
The builder is designed around small choices and a live preview. You do not need to understand book-production terminology before you start.
Choose the page style, size and page count. The preview updates as you go.
Start with the layout your reader will use every day.
On Pro, add a one-liner to each page to give a plain journal more personality.
Journal, gratitude journal or word search. Start with what you actually want to make.
Choose the available page style, size, page count, subject or other settings for that format.
Check the book, make sure it is the edition you want, then export the files for your KDP workflow.
Rank Fuel Content Studio helps you build KDP-ready book files without laying out every page by hand. Choose a supported book type and settings, then generate the interior and matching cover for review and export.
Current ready-to-use formats include journals and notebooks, gratitude journals, and word search books. More formats are being added to Content Studio.
Yes. The Notebook & Journal Maker handles lined, college-ruled, dot-grid and squared interiors. Optional one-liners are available on Pro.

Yes. Content Studio creates a matching cover for the generated edition so you do not have to work out the cover dimensions separately.
No. The point of Content Studio is to remove the repetitive page-building and formatting work. You choose the book and its options, then review the files it creates.
