Can I change how I am billed?

Yes. You can move between monthly and yearly billing whenever you like. Yearly costs $100 instead of $120, so you save $20.

What happens when I run out of usage?

Usage runs on two rolling windows — a 5-hour one and a weekly one — that refill on their own once time passes, not at a fixed clock time. If you don't want to wait, you can also buy credits to keep going, or upgrade to Pro for 5x the usage.

Is there a free trial?

Not yet, but we are working on it. For now the Free plan gives you a genuine feel for Kozrin before you commit.

How does yearly billing work?

One payment of $100 covers 12 months, which works out to about $8.33 a month. That is $20 less than paying $10 every month.

Can I cancel at any time?

Yes. Cancel from Settings and you keep access until the end of your paid period. No questions asked.
