Frequently asked questions:
Q: Why do some tools ask for a card even on free plans?
A: Fraud control and upgrade friction — card-on-file users convert better. The tools in this list skip that step entirely.
Q: What happens when I hit the free limit?
A: Typically generation pauses until the next monthly reset. Paid tiers of these ai agents AI tools raise or remove the cap.
