See the [Quickstart](/quickstart) for a step-by-step walkthrough. ## After the free trial When you're ready for more, [subscribe to a plan](https://sync.so/pricing). Subscriptions unlock: * Higher concurrency and longer video durations * Premium features like reasoning mode and automatic speaker detection * Access to [react-1](/models/react) for expressive lip sync with emotions * Usage-based billing — pay only for what you generate > **Note** > > 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](/product/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 text-to-speech generations each calendar month. If you generate voice audio with text-to-speech inside a lip sync workflow, that counts against the 10 text-to-speech generation allowance in addition to the lip sync generation 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). #### 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. #### 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 lip sync have separate monthly allowances on the free trial. Creating generated speech from text uses one text-to-speech generation; using that generated 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. #### Do I need a credit card to sign up? No. You can create a free account and start generating without providing payment information. ## Free Trial Reference ### Exact Limits | Resource | Limit | | ------------------------------------ | ----------------------------------------- | | Lip sync generations per month | 3 | | Max video duration per generation | 20 seconds (15 seconds for sync-3) | | Text-to-speech generations per month | 10 | | Credit card required | No | | Rollover | No — unused generations do not carry over | ### Available Models on Free Trial | Model ID | Available | | -------------------- | -------------------------------------------- | | `lipsync-1.9.0-beta` | Yes | | `lipsync-2` | Yes | | `lipsync-2-pro` | Yes | | `react-1` | No — requires paid subscription | | `sync-3` | Yes — 1 generation per month, 15 seconds max | ### What Free Trial Does NOT Include * react-1 model access * Concurrency beyond default limits * Video durations longer than 20 seconds (15 seconds for sync-3) * Team workspaces * Reasoning mode * Automatic speaker detection > Try sync. labs AI lip sync for free. 3 generations per month (including 1 sync-3), 20 seconds max (15s for sync-3), all lipsync models.
