What happens when you run out of Claude tokens for the day — do you have to wait until tomorrow like with some other chatbots?

No. Unlike some other AI tools where you're locked out until the next day, Claude lets you turn on 'usage credits' in org settings so that once your included allocation is used up, it keeps working and simply charges you for additional usage. You can also pre-purchase a credit balance at a discount (up to about 30% off) to draw from. In practice, even during intensive use, daily overage spend was reported as typically only $5–$6, which was framed as very cheap compared to the cost of an additional employee, though it was acknowledged that people may have different comfort levels with letting a tool spend extra money automatically.
