Buying more credits
Run low before your monthly reset? Buy a credit pack: +100 credits for $5, on any plan. Pack credits roll over and are used only after your monthly allowance is spent. You can also turn on auto top-up (off by default) to buy a pack automatically when you run out, up to a monthly cap you set.Paid plans are billed quarterly or yearly. For current prices and exact
allowances, the live pricing page is always the
source of truth.
