AI agents use AI credits when they reply. Your account has one shared pool of credits, and all your lines and agents draw from it. You can always see your balance in the Credits pill in the top bar.
The AI credits section of Billing with balance, buy credits, monthly add-on, and auto-reload

​
Where credits come from

The pool is filled from four sources: The Balance card in Billing → AI credits shows your current balance, how many credits you’ve used this period, how many are included monthly from your lines, and your current monthly add-on.

If you regularly need more than your lines include, a monthly add-on is simpler than buying packs.

Turn on auto-reload

Auto-reload tops up your credits automatically, so agents don’t stop replying in the middle of a busy campaign.

  2. Set your reload options.
  3. Click Save auto-reload.

​
Plan your credit usage

AI agents need credits to reply. If your balance hits zero, agents can’t respond until you add credits, and leads could wait. Turn on auto-reload or a monthly add-on before a big launch.
The Dashboard Activity Overview charts AI credits used against Messages each day. Use the trend to size your add-on.
No. Credits from every line go into one pool for the whole account, so a busy line can use credits included with a quieter one.
