Frequently asked questions

Is LuminaProse really free?

Yes. The Free plan is free forever — no trial period, no credit card required. You get 3 manuscripts (including a ready-made sample story), 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-5x, 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 $10/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?

Yes. LuminaProse is built for adult fiction — dark fantasy, horror, psychological thrillers, crime, and other genres that rely on violence, morally complex characters, on-page death, and adult themes. We don't add a content filter on top of the models. For darker generation we recommend our Mistral Medium model (available on Starter and above), which has the most permissive content policy of the platform-provided models. If you need fewer restrictions still, BYOK lets you route generation through your own OpenRouter key to any model OpenRouter supports.
