After the free trial

When you’re ready for more, subscribe to a plan. Subscriptions unlock:

Higher concurrency and longer video durations
Premium features like reasoning mode and automatic speaker detection
Access to react-1 for expressive lip sync with emotions
Usage-based billing — pay only for what you generate

Free-trial allowances apply only while your account is on the free plan. Paid plans do not include a monthly free-generation allowance: once you subscribe, generations are billed according to your plan and model usage. The Hobbyist plan removes the free-trial duration cap but still includes a watermark. Creator and higher remove watermarks.

See the Billing page for full plan details.

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 combined text-to-speech and dubbing generations per monthly allowance period, with up to 3 of the 10 used for dubbing. The audio allowance resets on a monthly cycle anchored to your organization’s creation date, not necessarily the first of the calendar month. Generating audio through TTS or dubbing and then lip-syncing it uses both the audio allowance and the separate lip sync allowance.

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 limits are 20-second max duration, 3 generations per month, and of those 3 generations, at most 1 can be sync-3 (15 seconds max).

Why don't I see the lip sync generate button on the free trial?

The generate button appears after the required inputs are added. Add one source video or image with a visible face, then add either an audio file or a text-to-speech input. If you still do not see the button, refresh the page and confirm you are signed in to the same account that has the free-trial allowance.

Does the Hobbyist plan remove the watermark?

No. Free and Hobbyist outputs include a sync watermark. Creator and higher remove watermarks from exports.

Is sync-3 available on the free trial?

Yes. You get 1 sync-3 generation per month with a 15-second max duration (compared to 20 seconds for other lipsync models). This lets you evaluate sync-3’s advanced capabilities before subscribing.

Why did a lip sync with generated speech use a text-to-speech generation?

Text-to-speech and dubbing share a 10-generation monthly audio allowance, with up to 3 used for dubbing. If you do not use dubbing, you can use all 10 for text-to-speech. Lip sync has a separate allowance. Generating speech or dubbed audio uses the audio allowance; using that audio in a lip sync also uses one lip sync generation.

Is react-1 available on the free trial?

No. 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) and sync-3.
