AI Credits

How Credits Work

Every AI action (extraction, generation, rewriting, side-panel chat) consumes credits from your monthly allotment. Credits reset on your billing cycle date. Unused credits do not roll over.

Credit Packs (One-Time Purchase)

Need more credits mid-cycle? Purchase a one-time pack. Purchased credits do carry over month to month and are used only after your base allotment runs out.

  • 250K credits
  • 500K credits
  • 1M credits

Check your current usage in Settings → Billing. The credit meter shows base credits, purchased surplus, and usage for the current cycle.

Upgrading & Downgrading

Upgrading

Go to Settings → Billing → Upgrade Plan or visit the /pricing page. You'll be redirected to Stripe Checkout. The new plan takes effect immediately, and your credit allotment adjusts.

Downgrading & Cancellation

You can cancel at any time from Settings → Billing. Your paid features remain active until the end of the current billing period. After that, your account reverts to the Free plan limits. Existing projects are not deleted — you just can't create new ones beyond the Free quota.

Managing Your Billing

All billing management is handled through the Settings → Billing tab:

  • View current plan, status, and next billing date
  • See AI credit usage (base + purchased + used this month)
  • Switch between monthly and annual billing
  • Purchase AI credit packs
  • Cancel or change your plan
