How Credits Work
Every AI operation in Fable — voice edits, agent checks, and more — uses credits. Credits are consumed based on how much AI processing your edit requires. Small changes use fewer credits; larger rewrites use more.
Each edit in the history shows its cost for full transparency, so you always know exactly what you're spending.
Free Credits
Every new account gets free credits to start with — no credit card required. This gives you plenty of room to try Fable and see if it's right for your workflow before committing to a plan.
Pro Subscription
The Pro plan gives you a monthly credit allowance that resets each billing cycle. It's designed for writers and teams who use Fable regularly. Subscription credits are always consumed first, before any top-up credits.
Top-Up Packs
Need more credits? Top-up packs are one-time purchases available in multiple tiers. Top-up credits never expire and are consumed after your subscription credits are used up.
You can buy top-ups whether or not you have a subscription — they're a great way to handle busy periods or one-off projects.
Credit Meters
The Settings > Billing page shows two separate progress bars:
- Subscription credits — shows how much of your monthly allowance remains
- Top-up credits — shows your remaining one-time credits
When credits run low, the meters change color to warn you. If you run out, an upgrade prompt appears with options to subscribe or buy a top-up pack.
Who Pays?
All AI costs are charged to the project owner's credits. Editors and viewers don't need their own credits — they use the owner's. This means you can invite your whole team without worrying about everyone needing their own subscription.
If the owner runs out of credits, editors and viewers will see a message to contact the project owner.
