Frequently asked questions
From the KU romance authors already writing with Belle.
What is the best AI writing tool for KU romance authors?
FinishTheBook.ai is the only AI writing platform built specifically for KU romance authors. Belle, the AI co-writer, knows your tropes, your heat level, and every chapter you have written. Quill, the autonomous editor, checks every save for continuity errors, voice drift, and romance pacing. Generic AI tools like ChatGPT and Sudowrite were not built for the rapid release schedule or the cross-book consistency that KU readers expect.
Can it help me hit a rapid release schedule?
Yes. The series bible and persistent story memory mean Belle never makes you re-explain your characters. By book three, she still knows that the second sister has the scar and that the hero promised something in chapter four of book one. That removes the biggest source of friction on a rapid release schedule: re-loading your own series into your head every time you sit down to write.
How does it keep my series consistent across multiple books?
Every series shares a single bible (characters, world, notes) and a running story memory of promises made, objects introduced, and relationship milestones. When you start book two, Belle sees everything from book one. Quill flags any continuity contradiction the moment you save the chapter, before your readers find it in a one-star review.
What is a romance beat sheet, and which subgenres do you support?
A romance beat sheet is a scene-by-scene roadmap showing where key emotional moments should land. FinishTheBook.ai includes subgenre-aware beat sheets for contemporary, dark, romantasy, cozy, and slow burn romance. Quill knows that a slow burn first kiss before chapter ten is a problem, and that a romantasy past 25% with no magic on the page is a problem. Generic beat sheets do not catch that.
How much does it cost?
FinishTheBook.ai is $69 per month or $690 per year. One price, every feature, no limits on series, books, or AI usage. 7-day free trial, no credit card to start, cancel before day 8 and pay nothing.
How is it different from Sudowrite, NovelCrafter, or ChatGPT?
Sudowrite and NovelCrafter were built for all fiction. ChatGPT was built for everything. FinishTheBook.ai was built only for romance authors, by a KU romance author. That means romance-specific beat sheets, heat level tracking, trope thread analysis, persistent story memory across a series, and an editor who knows what a black moment is supposed to look like at 75% of a manuscript.
