Subscription or Credit Packs?

A 30-second decision helper. Credits work the same either way — pick the option that matches how often you publish.

📚

You publish regularly

Planning one or more books a month? A subscription gives you the lowest cost per credit, credits every month, and you can cancel anytime.

  • Best value per credit — ideal for active publishers
  • Fresh credits every month, unused credits roll over
  • Cancel anytime — keep the credits you already have

Recommended: Creator plan

🎯

You publish occasionally

Working on one book, or publishing a few times a year? Buy a one-time credit pack — no recurring charge, and credits never expire.

  • Pay once — no subscription, no renewal
  • Credits never expire — use them whenever you're ready
  • Top up only when you need more

Recommended: One-time credit pack

Risk-free either way: start with 75 free credits (no card required), and if a generation fails, the credits are automatically refunded.

Pricing Questions

Your 75 free credits cover research, a full Book Blueprint, and the start of your first interior — a shorter puzzle book or a text-only journal can fit within them. Based on the last 60 days of real usage, complete books typically use 100–350 credits depending on type and page count, so most authors top up with a plan or pack to finish.
Choose a monthly or annual plan. Each billing cycle you receive your credit allowance instantly. Credits are good for any book type or action. Unused credits never expire — they roll over indefinitely. Annual plans save 33%.
Subscriptions give you the lowest per-credit rate and are best for regular publishing. Credit packs are one-time top-ups — great for occasional needs. Both types of credits never expire.
Absolutely. Cancel with one click from your dashboard. You keep access to all your remaining credits — they never expire, even after cancellation.
Credits are automatically refunded in full. You only pay for successful outputs.
No. All credits — whether from a subscription or a one-time pack — never expire. Use them whenever you're ready.
Yes. Changes take effect on your next billing cycle. If you upgrade mid-cycle, Stripe pro-rates the difference. You can manage your plan directly from your dashboard.
