Your plan includes a monthly AI usage allowance that resets each billing period — usage never bills past it. All paid plans use the same OpenAI models; a larger plan buys more turns, not extra models. Cancel or change plan any time from the billing portal; your remaining allowance keeps working until the period ends. By subscribing you confirm you are 18 or older and agree to the Terms and Privacy Policy; the agent is an AI system and its output should be checked before you rely on it.
