LitRPG Series Launch Studio
A prompt engine for LitRPG authors on Kindle Unlimited: one Series Profile, seven modes for market fit, editing, listing polish, back matter, reader magnets and cover briefs, plus an instant KDP royalty calculator.
How it works
You fill your Series Profile once: the title, the pen name, the story type (what your hero mostly does), the feel, the setting, where you are in the series, the hero and premise in two lines, and your reader. Then you paste whatever you are working on into The Page: a chapter, the listing, the story page, or a chapter plan. Pick one of seven modes and the Studio assembles one complete prompt from all of it. You copy it into your own AI chat and run it there. The prompts are the product; every mode carries the genre rules a generic writing tool does not know: what KU readers binge, which review-killers cost a LitRPG book its ranking, how covers in this genre read at thumbnail size. The seventh mode needs no AI at all: a KDP royalty calculator that shows its inputs and its assumptions.
What's inside
- Series Profile plus The Page: shared inputs every mode reads, saved to your account so the profile is there next session.
- Market Fit: a web-search prompt for the story-type and feel combinations KU readers are buying this quarter, title and subtitle conventions, and Amazon categories.
- Editor's Pass: a genre-editor prompt over your pasted chapter, aimed at the review-killers: AI telling, stat dumps that stop the story, System box voice changes, and chapters that end without a page-turn reason.
- Listing Polish: a listing rewrite for the eight-second phone decision: hook first line, genre signals, the seven keyword slots, categories, and an A+ content plan.
- Back Matter: the closing pages that keep a series alive: Book 2 teaser, review page, newsletter page, a new-to-LitRPG page, and the author's note.
- Reader Magnet: a prequel short story, character sheet pack, or System manual in your series voice, plus the sign-up page copy and welcome emails.
- Cover Brief: an image prompt and typography spec that follow LitRPG cover rules (lone hero, the glow, System-box typography, series badge), with a series set so Books 1 to 5 match.
- Royalty Calculator: instant KDP maths with shown inputs: ebook royalties at 35% and 70%, a full KU read, the paperback royalty, and the value of one Book 1 reader across the series.
Frequently asked questions
How much of my profile do I have to fill in?
None of it is required. Fill in what you know, once; every field is optional, and where one is empty the prompt tells the AI to choose something fitting instead of inventing a fact about your series.
What does the Royalty Calculator use?
KDP's published rules, with the assumptions printed next to the results: the 70% royalty band minus the delivery cost from your file size, the 35% royalty, a full Kindle Unlimited read from your KENP page count and the per-page rate you enter, and the paperback royalty of 60% of list minus the printing cost. The series maths then values one Book 1 reader across the series at your read-through rate and KU share.
Does ContentCraft write the chapters, the listing or the back matter for me?
No. The Studio builds a complete prompt from your Series Profile, The Page, and the mode you pick, and you run it in your own ChatGPT, Gemini, Copilot, or Grok. Nothing is written by an AI on our servers. The Royalty Calculator is the one exception: it does the maths here, instantly, with no AI at all.
