Series Planner
Describe the series you're imagining — get the throughline that carries readers across every book, plus a real premise and arc for Book 1.
2 generations per hour, free — same limit as everywhere else on this page.
How this plan is built
Why only Book 1?
A series bible for every book is most of the planning work — we generate the throughline and a real, detailed Book 1 for free, then simply list the rest by number. Nothing about Book 2 onward has actually been written yet; there's nothing hidden to unlock, only more to plan.
What "series arc" means
The one or two sentences that explain why a reader who finishes Book 1 needs Book 2 — the question, tension or mystery that no single book resolves on its own.
Questions authors actually ask
Do the books planned have to be fiction?
This tool is built for fiction series specifically — nonfiction series (a course, a workbook set) plan differently, book by book, without a single narrative arc pulling readers through.
Why does it say I've hit the limit?
Each visitor gets 2 generations per hour, so this stays free for everyone rather than a few people running it on repeat. Wait for the timer, or start your series properly — the Assistant has no limit like this.
Can I change the number of books after I see the plan?
Yes — adjust "Books planned" and generate again (within your 2 tries this hour). The series arc and Book 1 will usually stay close; the count is what changes.
