You can have Kitt AI automatically add credits once your account balance falls below a certain threshold.
To do this, click in the left navbar on Billing >> Payments >> Auto Recharge Settings
By clicking on the Auto Recharge Settings button, you will get the following options:
Auto Recharge Threshold: specifies the minimum account balance that you want to maintain in your account as a safety buffer.
Auto Recharge Credit Amount: specifies how much you want your card to be charged once the Threshold is hit.
Limit Auto Recharge: you can use this to block runaway spent by putting an effective 'spending' cap.
For example, let's say you put your Recharge Threshold at $100 and your Recharge credit amount at $50 and recharge limits to 2. If your balance falls below one hundred dollars, it will automatically topped back up to $150. If it falls below $100 again, it will be topped up to $150 again. However, if your balance falls below $100 a third time, it will not recharge until the next day, so you could potentially run out of credits during that period.
