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.
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.
All your existing worlds are preserved. You just won't be able to use AI generation beyond your new plan's limits until the next billing cycle.
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.
Yes. You retain 100% ownership of all content you create with Novarrium. This includes characters, worlds, maps, chapters, and everything you build.
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.
