Frequently Asked Questions
Do free generations roll over to the next month?
No. Unused free generations do not roll over. You receive 3 fresh lip sync generations and 10 text-to-speech generations each calendar month.
Can I use lipsync-2-pro on the free trial?
Yes. All lipsync family models are available on the free trial, including lipsync-2-pro. The only limitation is the 20-second max duration and 3 generations per month.
What happens if I subscribe mid-month?
Once you subscribe, you move to usage-based billing immediately. There is no monthly free generation allowance on paid plans — you pay for what you generate.
Is react-1 available on the free trial?
react-1 requires a paid subscription. On the free trial, you can use any lipsync family model (lipsync-1.9.0-beta, lipsync-2, lipsync-2-pro).
Do I need a credit card to sign up?
No. You can create a free account and start generating without providing payment information.
