​
Plans

All packs share the same platform-wide tiers. Pricing is per-account, not per-pack.
1 Story Unit = 5 NPCs, 1 encounter, or 1 session recap. BYOK (Bring Your Own Key) is available on all paid plans - you pay your own LLM provider costs directly, with zero markup from us.

​
Story units

Story Units (SU) are the universal usage currency across all packs. Every API operation that involves LLM generation consumes Story Units: When your Story Unit quota is exhausted, the API returns HTTP 402 with error code budget_exceeded. Upgrade your plan or wait for the next billing cycle.

​
Usage metering

Usage resets on your billing cycle date. Query your current usage:

Payment processing

Billing is processed by our payment provider. When you subscribe:
  1. A customer record is created linked to your account.
  2. A subscription tracks your plan and billing cycle.
  3. Story Unit usage is reported to the payment provider at the end of each period.
  4. Invoices are emailed automatically and available in Settings → Billing.

​
Upgrading and downgrading

Plan changes take effect immediately. When upgrading mid-cycle:
  • You are charged a prorated amount for the remainder of the period.
  • Your Story Unit limit increases immediately.
When downgrading mid-cycle:
  • The new plan takes effect at the start of the next billing period.
  • No refund is issued for unused capacity.

Dunning and failed payments

If a payment fails, the payment provider retries on days 3, 5, and 7. After the final retry, your account is downgraded to Free and generation access is suspended until payment is resolved.
