Tokens are units the AI uses to process text. Usage varies depending on your input length, prompt context, and output length.

Not at this time. Kotofy is currently intended for use on one Mac, and your account does not transfer automatically to another Mac or a fresh reinstall. If you move to a new Mac, cancel your current subscription first and start a new subscription on the new device.
