Lip sync AI is free in two forms. Hosted free tiers give a few short, watermarked clips: Magic Hour allows three 10-second lip syncs a day with no account, and a free Sync account allows three 20-second generations a month. Open-source models are unlimited and unmarked on your own GPU; MuseTalk is the one licensed for commercial use, while Wav2Lip is non-commercial only.
Lip sync AI is free in two forms: hosted tools that give you a few short, watermarked clips, and open-source models that give you unlimited clips with no watermark if you run them on your own GPU. The most generous hosted option we could document is Magic Hour's free tool, three lip syncs a day of up to 10 seconds with no account; the best-licensed local one is MuseTalk, which is MIT and allowed for commercial use.
Limits checked October 2026 against Magic Hour's Lip Sync page and pricing, Sync's free plan docs and billing docs, Kapwing's credits page and Lip Sync page, Kling's Lip Sync page, and the MuseTalk, LatentSync, Wav2Lip and InfiniteTalk repositories.
Everything here comes from what vendors and repositories publish. We did not render clips and grade them, so the "quality" column you may expect is replaced by something you can verify: the output size and limits each source documents. Paid tools and per-second prices are in our best lip sync AI comparison, and the wider video stack is in the AI influencer video generators ranking.
Lip sync AI free: every option at a glance
| Option | Free allowance | Max clip length | Watermark | Login | Commercial use |
|---|---|---|---|---|---|
| Magic Hour free tool | 3 lip syncs a day | 10 seconds | Yes | No account needed | Personal, non-commercial |
| Sync free account | 3 generations a month (one may be sync-3), plus 10 text-to-speech | 20 seconds; 15 on sync-3 | Yes | Account, no credit card | Not stated in the billing docs |
| Kapwing Free | 10 credits, once; lip sync costs 30 credits a minute | About 20 seconds in total | Small watermark | Sign-in offered; requirement not stated | Not stated |
| lipsync.video | Advertised as free; credit amounts not stated | 90 s or 30 s by model, per its page | Says none | Not stated | No terms on the page; operator not named |
| Kling Lip Sync | None: described as a paid feature | n/a | n/a | Kling account | Per Kling plan |
| MuseTalk (local) | Unlimited | No cap stated | None | None | MIT; commercial use allowed |
| LatentSync (local) | Unlimited | No cap stated | None | None | Code Apache-2.0; checkpoints OpenRAIL++ |
| InfiniteTalk (local) | Unlimited | Unlimited by design | None | None | Apache 2.0 |
| Wav2Lip (local) | Unlimited | No cap stated | None | None | Non-commercial only |
"Not stated" means the page we read did not say, not that the answer is yes. Free allowances change often; the number in your account is the one that counts.
Two patterns stand out. Every hosted free tier we could verify is short: none documents a free clip longer than 20 seconds. And no hosted free tier we could verify is both unmarked and licensed for commercial use. If you need either, you are choosing between a paid plan and a local model.
Lip sync AI online free: how far the hosted tiers stretch
Counted over a month, the three documented free tiers are not close to each other.
Source: Magic Hour Lip Sync page, Sync free plan docs, Kapwing credits page; checked October 2026. Magic Hour figure is 3 clips of 10 s a day for 30 days.
- Magic Hour. Its Lip Sync page says you get three free lip syncs a day with no account needed, with a 10-second maximum in the free tool. Results are watermarked and for personal, non-commercial use. It takes a video with a visible face plus audio, in MP4 or MOV.
- Sync. A free account gets three lip sync generations a month, up to 20 seconds each, on the lipsync-1.9, lipsync-2 and lipsync-2-pro models; one of the three can use sync-3, capped at 15 seconds. It also includes 10 text-to-speech generations, but using that generated speech in a lip sync spends one of the three lip sync generations as well, so settle the audio before you start. No credit card is needed, unused generations do not roll over, and outputs carry a Sync watermark.
- Kapwing. The free plan comes with 10 credits for the lifetime of the account, and lip sync costs 30 credits a minute, so the free credits cover about 20 seconds, once. Free exports carry a small watermark. Its lip sync sits inside the dubbing workflow.
- Kling. Kling calls Lip Sync a paid feature, and it only works on clips generated in Kling.
Free lip sync AI without watermark: what is really available
On hosted tools, the watermark is the price of free. Magic Hour removes it for paid subscribers and credit-pack buyers. Sync keeps it on the free and Hobbyist tiers and removes it from the Creator plan. Kapwing removes it on Pro. Cropping or painting out a mark does not change the non-commercial terms the clip was made under.
That leaves one free route with a clean frame: an open model on your own machine. Nothing is added to the output because there is no service in the loop.
- Works in a browser in a minute
- Clips of 10 to 20 seconds
- Watermark on every free result
- Non-commercial, or terms not stated
- Your footage is uploaded to the vendor
- An evening of setup, then no per-clip cost
- No documented length cap
- No watermark
- License varies: MIT, Apache-2.0 or non-commercial
- Footage never leaves your computer
One name needs a caution. A site that markets itself on exactly this promise, lipsync.video, advertises free lip sync downloads without a watermark. Its page lists two models (90-second and 30-second limits, at 1 and 4 credits a second) but does not name the company running it, state how many free credits you get, or show terms for commercial use. We list it as unverified. If you try it, use footage you would not mind losing control of.
Lip sync AI free unlimited: the local route
Unlimited free lip sync exists, and it is a download, not a website. Four open models cover it. The differences that matter are the GPU each needs and what its license lets you do with the result.
| Model | VRAM documented | Output | License | Use it for |
|---|---|---|---|---|
| MuseTalk 1.5 | Tested on 4 GB (RTX 3050 Ti laptop) | 256 by 256 face region, pasted back into your frame | MIT; commercial use allowed | Most people, and all paid work |
| LatentSync 1.5 | 8 GB | Trained on 256 by 256 faces | Code Apache-2.0; checkpoints OpenRAIL++ | Mid-range cards |
| LatentSync 1.6 | 18 GB | Trained at 512 by 512 to reduce blur | Code Apache-2.0; checkpoints OpenRAIL++ | Close-ups, if you have the VRAM |
| InfiniteTalk | Not given in GB; quantised version for low memory | 480p or 720p; moves head and body too | Apache 2.0 | Long dubs and image-to-video |
| Wav2Lip | Not stated | Low-resolution faces | Personal, research, non-commercial | Learning and private tests only |
MuseTalk is the default recommendation here for a reason that has nothing to do with looks: its repository says the code is MIT with no limitation on academic or commercial use and that the trained model is available for any purpose, even commercially. It is also the lightest, with a minimum tested setup of a 4 GB laptop GPU where an 8-second video took about 5 minutes. The repository is frank about limits: resolution below the theoretical bound, some loss of detail such as moustache and lip colour, and some jitter.
Wav2Lip is the model most forum threads still send people to, and it is the one to keep away from paid work. Its repository restricts it to personal, research and non-commercial purposes and states that any form of commercial use is strictly prohibited. A sponsored Reel is commercial use.
- 1Check the GPU
An NVIDIA card with 4 GB of VRAM or more. No card: rent one by the hour instead.
- 2Set up the environment
Follow the repository README; it recommends Python 3.10 and CUDA 11.7 and lists the model weights to download.
- 3Prepare the video
A clip where the face is visible and already moving as if speaking. The README recommends 25 fps input.
- 4Prepare the audio
One clean voice track, trimmed to the length of the clip.
- 5Run inference
Point the config at the video and the audio. Expected result: a new video in the results folder with the mouth redrawn.
- 6Fix softness if you see it
The README suggests a face super-resolution model such as GFPGAN when the mouth region looks soft.
No GPU at all? An hourly cloud GPU turns "free" into cents per session rather than dollars per clip; our cloud GPU hosting comparison lists the options, and how to make AI influencer videos for free covers the rest of a zero-budget pipeline.
Which free lip sync option fits what you are making
On output size, which is as far as documentation goes on quality: Sync describes lipsync-2 as a 512 by 512 model and sync-3 as native 4K, MuseTalk redraws a 256 by 256 face region, LatentSync 1.6 was trained at 512 by 512 specifically to reduce blur, and Wav2Lip was trained on low-resolution faces. A larger face region gives the model more pixels to draw teeth and lip edges with. Whether that shows on a phone screen depends on how close the shot is, which is the test worth running on your own footage.
Free lip sync from a photo instead of a video
Re-sync tools need footage. If all you have is a still, you want an image-to-talking-video tool instead. The free ones: HeyGen's free plan lists three videos a month of up to one minute with a photo avatar; Hedra has a free plan whose outputs are watermarked and non-commercial; SadTalker and InfiniteTalk do it locally under Apache 2.0. The limits of each are in our comparison of free talking avatar generators.
When free stops being worth it
The moment a clip has to be posted clean or a brand is involved, the hosted free tiers are finished. The cheapest documented step up is small: Sync's Hobbyist plan is $5 a month plus $0.05 a second for lipsync-2, though it still carries a watermark, and Creator at $19 removes it. A 30-second clip is then about $1.50 in usage. The per-tool cost comparison is in our best lip sync AI page.
Lip sync is also the last five percent of a talking video. The face, the voice and the script decide whether anyone watches it, and that pipeline is what the AI Influencers program covers.
- A named company and a terms page you can read
- The free allowance stated as a number, with its reset period
- Maximum clip length on the free tier
- Whether free output is watermarked, and which plan removes it
- Commercial-use terms for free output
- How long your uploads are kept; Magic Hour states one day
- For local models: the license of the code and of the weights
- Footage and voice that are yours, or used with written permission
The last line is not a formality. Lip sync puts words in a mouth. Use it on your own persona, your own face or footage you have consent for; our AI likeness rights guide explains why.
Free lip sync AI: FAQ
Is there a free lip sync AI?
Yes. Magic Hour's free tool allows three lip syncs a day of up to 10 seconds with no account. A free Sync account includes three generations a month of up to 20 seconds, and Kapwing's free plan has 10 one-time credits, about 20 seconds of lip sync. All three watermark free output. Open-source models such as MuseTalk are free without a cap on your own GPU. Checked October 2026.
Is there a free lip sync AI without a watermark?
Not among the hosted free tiers we could document: Magic Hour, Sync and Kapwing all mark free output, and remove the mark on paid plans. The free route with no watermark is an open-source model you run yourself, such as MuseTalk, LatentSync or InfiniteTalk. One site, lipsync.video, advertises free unmarked downloads, but its page names no operator and states no terms.
Is there an unlimited free lip sync AI?
Only locally. Every hosted free tier is capped by clips per day, generations per month or one-time credits. Open models have no usage cap because they run on your own hardware: MuseTalk was tested on a 4 GB laptop GPU, LatentSync 1.5 needs 8 GB of VRAM and LatentSync 1.6 needs 18 GB. Unlimited here means limited by your GPU and your patience instead.
Can I use lip sync AI online free without signing up?
Magic Hour says so directly: three free lip syncs a day with no account needed, each up to 10 seconds, watermarked and for personal, non-commercial use. Sync requires a free account but no credit card. Be careful with unnamed sites that promise unlimited lip sync with no sign-up; you are uploading a face and a voice to an operator you cannot identify.
Can I use Wav2Lip for free on commercial videos?
No. Wav2Lip is free to download, but its repository limits it to personal, research and non-commercial purposes and says commercial use is strictly prohibited because of the dataset it was trained on. For sponsored posts or client work on a local model, use MuseTalk, whose code is MIT licensed and whose repository allows commercial use of the trained model.
What GPU do I need to run lip sync AI locally?
Less than most video models. MuseTalk's repository reports a minimum tested setup of an RTX 3050 Ti laptop GPU with 4 GB of VRAM, where an 8-second video took about 5 minutes. LatentSync lists 8 GB for version 1.5 and 18 GB for version 1.6. InfiniteTalk is built on a 14B video model and offers a quantised version for lower memory.
Can free lip sync AI make a photo talk?
Yes, but that is a different kind of tool. Re-sync tools need a video of a face. To animate a still image for free, HeyGen's free plan lists three one-minute photo avatar videos a month, Hedra has a watermarked non-commercial free plan, and SadTalker and InfiniteTalk do it locally under Apache 2.0. MuseTalk also accepts a single image as its visual input.
Free tools sync a mouth. A persona needs the whole face, voice and plan.
Once the lip sync works, the question is what your persona says and how often. AI Influencers, included in All Access, covers the consistent character, the voice and the weekly video workflow, with the other three programs, live coaching and the private community in one subscription.
