Beat and scene generation that fits your story

From blank page to finished story

Three steps to writing with full AI support for your story world

1

Import or start your manuscript

Paste existing text, upload a Word document, or start from scratch. LuminaProse organises your content into a continuous manuscript with chapter structure.

2

Build your story bible

AI reads your manuscript and extracts characters, locations, arcs, and themes into a structured bible. Edit, enrich, and add details — the AI learns as you do.

3

Write with an AI that knows your world

Generate beats, scenes, or full chapters. Every prompt is enriched with your story context — the AI knows who your characters are, where they are, and what's at stake.

The new way to write stories.

"It was night and day from one draft to another. My writing speed went from single chapters to multiple chapters per session. It just spread like wildfire through my writing process."

Sarah Chen
Bestselling Author

"The most useful AI writing tool I've used, hands down. It's fast, maintains character voice, handles continuity properly — everything is well put together."

MW
Marcus Williams
Fantasy Novelist

"The best AI writing tools give you control: you decide how much independence to give the AI. In LuminaProse you can do targeted scene generation, full chapter drafting, or let it assist with worldbuilding."

Elena Rodriguez
Thriller Writer

"LuminaProse quickly became essential. We spend more time on creative storytelling than any other part of writing — and there's significant value in making that process more efficient."

DK
David Kim
Screenwriter

"I love LuminaProse's structured approach. It's wild how much it helps maintain consistency across a full novel. I won't write a book without it now."

"Writing is becoming more fun. Less about managing continuity, more about what you want to happen in your story. Models like Claude Sonnet shine brightest in structured tools like this."

Frequently asked questions

Is LuminaProse really free?
Yes. The Free plan is free forever — no trial period, no credit card required. You get 2 manuscripts, AI generation, and full access to the story bible tools. Upgrade to Starter or Pro when you want more manuscripts, better AI models, or image generation.
What AI models does LuminaProse support?
LuminaProse routes through OpenRouter to support GPT-4o, Claude Sonnet 4, Grok, DeepSeek, Gemini Flash, and Claude Haiku — with more added regularly. Free tier uses DeepSeek Flash (fast, high quality). BYOK plan lets you use your own OpenRouter key and access any model at provider cost with no markup.
How does the AI know my story world?
Every time you generate text, LuminaProse builds a context packet from your story bible — your characters (with descriptions and arcs), locations, active themes, and a story-so-far summary. The AI writes as if it has read your entire manuscript. You control exactly which elements are included.
What is BYOK and how does it work?
BYOK (Bring Your Own Key) means you provide your own OpenRouter API key in your account settings. When you generate text, your key is used directly — LuminaProse charges no platform markup on API calls. You pay OpenRouter's rates (often fractions of a cent per generation) plus the $9.99/month platform fee. Great for heavy users and those who already have OpenRouter accounts.
Is my writing stored securely?
Yes. Manuscripts are stored in an encrypted Azure SQL Database. Your API keys (if using BYOK) are encrypted at rest using ASP.NET Data Protection. We never read your manuscripts or share your data. See our Privacy Policy and Security pages for full details.
Can I export my manuscript?
Yes — Starter and Pro users can export to DOCX (Microsoft Word), PDF, and plain text. Free users can copy their manuscript text at any time. Your writing is always yours.
Do you support mature or dark fiction content?
LuminaProse is designed for serious fiction writers — including those writing dark fantasy, horror, psychological thrillers, and crime fiction. Generation parameters let you control tone, intensity, and dialogue style. We're working on expanded mature-content model options for authors who need them.
