Frequently Asked Questions

Each has a free tier you can use without a card. The free plans have limits on usage, model access or exports, but they produce useful output rather than acting only as a short trial.

Possibly, for higher limits or team features. But for personal, occasional use the free tiers are often enough. Confirm current limits on the official site before signing up.
