Frequently Asked Questions

How does the free trial work?

Sign up and generate 3 chapters for free — no credit card required. You get full access to Creator-tier features to write at your own pace. If you like what you see, upgrade to keep creating.

Can I change plans at any time?

Yes! You can upgrade or downgrade your plan at any time. When upgrading, you'll get immediate access to new features. When downgrading, changes take effect at the end of your current billing period.

Can I plan a 35-chapter novel on the Creator plan?

Yes! All plans support novel-length projects with 35+ chapters. The monthly limit is how many chapters you can generate per month, not how large your project can be. On Creator (15/month), you can outline a 35-chapter novel and generate chapters over a couple months, or buy chapter packs for extra generations anytime.

What happens to my novels if I downgrade?

All your existing novels are preserved. You just won't be able to generate new chapters beyond your new plan's limits until the next billing cycle.

Can I cancel anytime?

Yes. You can cancel your subscription at any time from your account settings. Your access continues until the end of your current billing period, and you won't be charged again.

Do I own the content I create?

Yes. You retain 100% ownership of all content you create with Novarrium. This includes characters, plots, chapters, and complete novels.

What AI models power the writing?

We use Claude (by Anthropic) for prose generation and Gemini (by Google) for analysis and consistency. All tiers use the same high-quality AI models.
