What Makes Storyline Different
- Full Book Blueprint in 60 Seconds — Answer 3 questions and get a complete title, premise, chapter-by-chapter outline, characters, and writing approach.
- Context That Spans the Whole Book — Unlike ChatGPT, Storyline knows every chapter, every character, and what happened three scenes ago — so the AI never contradicts itself.
- Four Writing Modes — Co-Write (AI writes alongside you), Guided (prompts at every paragraph), Free Write (distraction-free), and Voice Dictation (speak your draft).
- Story Bible Built Automatically — Characters, locations, timeline, and key events tracked as you write so you never lose continuity across a 300-page manuscript.

- Literary fiction & novels — develop plot, subplots, and characters that stay consistent
- Self-help & business books — organize chapters around clear outcomes and frameworks
- Children's books — short arcs with age-appropriate language and pacing

Frequently Asked Questions
Is Storyline better than ChatGPT for writing a book?
ChatGPT is a general assistant — it has no memory of previous chapters, no outline, and no character tracking. Storyline is purpose-built for books: it generates a full blueprint first, then keeps your entire story in context as you write each chapter.
What AI model does Storyline use?
Storyline uses Claude by Anthropic — one of the strongest models available for long-form creative writing. Your writing is never used to train AI models.
Can I import a draft I already started?
Yes. Upload a .txt or .docx file and Storyline maps it to chapters so you can continue from where you left off.
What formats can I export to?
Word (.docx), PDF, and ePub. Basic plans include Word and PDF; Pro adds ePub.
Is there a free trial?
Yes — 7-day free trial with no credit card required. Full access during the trial.
