Change plans in Settings → Billing → Manage Subscription.
- Upgrading (e.g. Starter → Pro): takes effect immediately. You're charged the prorated difference for the remainder of the period, and your credit allowance and limits update right away.
- Downgrading (e.g. Pro → Starter): takes effect at the next billing cycle. You keep the current plan's credits and limits until then, and there's no immediate charge.
- Monthly → yearly: switches you to the discounted yearly price with the full year's credits granted upfront.
Pro differences worth knowing before you switch: 5,000 credits/month, cheaper per-generation costs, unlimited brands and team members, and 0% AI CMO platform fee on your own ad account, see Plans and pricing.
