Purchase credit packs from Settings > Account > Buy credits.
Overage billing
By default, Omnilib stops processing AI requests when you reach your monthly token limit. To continue after your quota is exhausted, enable overage billing:
- Go to Settings > Account.
- Toggle Enable overage on.
When overage is enabled, Stripe meters your usage above the monthly quota and bills you at the end of the billing period at your plan's overage rate. You can disable overage at any time; charges already accrued in the current period remain due.
Warning: Overage billing can accumulate costs quickly if you use AI-intensive features heavily. Monitor your usage to avoid unexpected charges.
Tracking token usage
View your current period token usage in Settings > Account. The usage bar shows how much of your monthly quota you have consumed and how much remains.
Usage resets at the start of each billing period (the anniversary of your subscription date).
Failed payments and grace period
If a payment fails, Omnilib retries automatically and sends an email notification. You have a 3-day grace period to update your payment method before your account downgrades to the Free tier. Update payment details in Settings > Account > Billing.
Managing your subscription
- Upgrade or downgrade: Go to Settings > Account > Subscription. Upgrades take effect immediately; downgrades apply at the next billing period.
- Cancel: Cancellation stops renewal at the end of the current period. Your plan remains active until the period ends.
- Receipts: Past invoices are available in Settings > Account > Billing history.
