TL;DR

Short answer: HeyGen has the clearest free lip sync offer: 3 videos a month, clips up to one minute, and limited trial access to lip-sync translation, according to its pricing page checked on October 10, 2026. Magic Hour offers free daily credits, and LatentSync costs nothing to use if you can run it on a GPU with 8 GB of video memory.

"Free" hides three different limits: how much you can generate, whether the output carries a watermark, and how long one clip can run. Most free plans here either add a watermark or cap the clip, and the paid tiers that remove the watermark start at $12 to $29 a month.

7 tools compared: HeyGen, Magic Hour, LatentSync, Wav2Lip, Kapwing, Captions, Sync
Magic Hour (best for: Anyone who wants a free allowance that renews each day, rather than a one-off trial balance): Free daily credits, with a possible watermark on free video. Plans from $12/mo on yearly billing.
LatentSync (best for: Developers and studios that can run a GPU and want no monthly fee or usage quota): Free under Apache-2.0. You supply the GPU: at least 8 GB of VRAM for inference.

A lip sync tool makes a speaker's mouth match a new audio track. The free plan decides whether you can test that on a real clip before paying. The seven tools below each offer a free plan, free code or a free try, and we read those terms on the vendor's own page.

We did not run any of them on test footage, so this page compares limits and prices, not output quality.

Toolradar data: Toolradar tracks 11,053 tools across 343 categories (toolradar.com/best, checked October 10, 2026).

Its pricing comparisons for HeyGen and Kapwing set them against only three and four comparable tools, so for this niche the vendor pages carry most of the weight.

HeyGen

Top Pick

Best for: Creators who want to test lip-sync translation on short clips before paying.

PricingFree: 3 videos a month, up to 1 min. Creator from $29/mo ($24 billed yearly).

+The free plan costs $0, with a monthly video cap and clips up to one minute each.

+The FAQ names limited trial access to lip-sync translation on the free plan, so the feature can be tested before you pay.

+Creator adds 600 credits, videos up to 30 minutes and watermark removal.

−Watermark removal starts at Creator, so do not assume free exports are clean.

−That monthly cap is small for any weekly publishing schedule.

Magic Hour

Best for: Anyone who wants a free allowance that renews each day, rather than a one-off trial balance.

PricingFree daily credits, with a possible watermark on free video. Plans from $12/mo on yearly billing.

+The free plan renews daily, so its credits refill each day.

+Credit packs sell at $1 for 400 credits, and the page says they carry no watermark and never expire.

+Lip Sync is one of its listed tools, alongside dubbing and subtitle generators.

−The page does not print the number of free daily credits, so you cannot size a free week from it.

−Free video and audio outputs may include a watermark, and the page does not say which free features include lip sync.

LatentSync

Best for: Developers and studios that can run a GPU and want no monthly fee or usage quota.

PricingFree under Apache-2.0. You supply the GPU: at least 8 GB of VRAM for inference.

+Apache-2.0 is a permissive license, so commercial use is allowed under its terms.

+The repository sets a VRAM minimum for inference, a level many consumer graphics cards meet.

+No hosted quota applies, so your cost is compute and time rather than a monthly allowance.

−You install the checkpoints and dependencies yourself, which takes real time for a non-developer.

−There is no vendor to contact when a run fails, so you rely on the repository and your own debugging.

Wav2Lip

Best for: Students and researchers who need a free lip sync baseline and will not sell the output.

PricingFree code for personal and research use. The repository bars commercial use and sends buyers to Sync Labs.

+The code is free to download and run locally.

+No hosted quota applies, because you run the model on your own machine.

+The authors name a hosted commercial route, so a paid option exists if the project grows into client work.

−The license says any commercial use is strictly prohibited, so a client video cannot use it.

−You set it up yourself, and it is a research release rather than a finished product.

Kapwing

Best for: Teams that edit video in a browser and need lip sync only after the free tier runs out.

PricingFree: 10 credits, watermark on every export. Lip sync needs Business at $50/mo billed yearly.

+The free plan costs $0 and includes 10 credits, 720p export and exports up to 4 minutes long.

+Pro at $16 a month billed yearly removes the watermark and adds 1,000 credits a month.

+Business adds lip sync videos and custom voice clones, plus 4,000 credits a month.

−Lip sync is absent from both Free and Pro, so the free tier does not answer a lip sync question.

−Kapwing says it offers no free trial of its paid plans, so the free tier is the only test you get before paying.

Captions

Best for: Short-form creators working on an iPhone who want captions and edits first and AI features later.

PricingFree plan with no AI credits. Max from $24.99/mo. The page says its prices reflect iOS plans only.

+The free plan covers basic tools such as trimming and transitions.

+The Max plan is $24.99 a month and includes 500 credits a month with the AI features.

+The comparison table lists AI Lipdub under one-tap translation, next to AI Translate, so dubbing and lip sync are grouped together.

−The page says its prices reflect iOS plans only, so a web or Android buyer should check the price in their own store.

−The free plan has no AI usage credits, so every generative feature is a paid decision.

Sync

Best for: Developers and teams that need an API for lip sync and are happy to pay per second of footage.

PricingHobbyist $5/mo plus $0.05/sec, videos up to 1 min. No free allowance printed on the page.

+Pricing is per second of video, so a 10-second test adds $0.50 on top of the plan fee.

+Creator at $19 a month lists no watermark and extends clips to 5 minutes.

+The Hobbyist fee is the lowest flat monthly price on this list, before per-second usage.

−The page prints no free allowance; its only free wording is a Try sync for free button on the Hobbyist card.

−Hobbyist clips stop at 1 minute and run one job at a time, which slows a batch.

What it is

A lip sync tool changes the mouth movements in a video so they follow a different audio track. Dubbing teams use it to put a translated voice on an existing speaker, and creators use it to make a presenter's mouth follow a voiceover.

The category overlaps with avatar generators and dubbing software, and the free plans differ mostly in how they meter that work.

If you need the wider category, our AI dubbing tools guide covers translation pipelines, and our free AI video generators guide covers the plans that make the clip itself.

Why it matters

A free plan can settle a choice in an afternoon. That monthly cap is enough to test one speaker and one language. It is not enough to publish a weekly series.

Read the free terms against the output you need: a watermark on a test clip is fine, and a watermark on a client delivery is not.

Our HeyGen pricing guide covers the plan ladder in more depth, and our HeyGen review covers the product itself.

Key features to look for

Free allowance

HeyGen gives a monthly video cap, Kapwing gives a credit allowance, and Magic Hour gives free daily credits with no amount printed. A monthly cap is easy to plan around, but daily credits are hard to size from the pricing page alone.

Clip length

HeyGen's free videos run up to 1 minute. Kapwing's free exports stop at 4 minutes, and Sync's Hobbyist lip sync stops at 1 minute, rising to 5 minutes on Creator.

Watermarks

HeyGen lists watermark removal only from Creator up. Kapwing removes its watermark on Pro, and Magic Hour's paid plans and credit packs remove it. Sync's Hobbyist card does not list watermark removal.

Lip sync on the free tier

HeyGen's free plan names limited trial access to lip-sync translation. Kapwing lists lip sync videos only on Business, and Captions' free plan has no AI usage credits.

Open source or hosted

LatentSync and Wav2Lip are code you run on your own machine. The other tools are hosted and bill by plan, credits or seconds of video.

Pricing

Every price here is the figure the vendor's own pricing page showed when we checked it on October 10, 2026: HeyGen pricing, Magic Hour pricing, Kapwing pricing, Captions pricing and Sync pricing.

The open-source rows link to their license pages: LatentSync and Wav2Lip.

Hedra pricing is not ranked because its plan table lists no free plan.

Methodology: we recorded each tool's free allowance, the longest clip its free or entry plan allows, its watermark rule and the cheapest paid tier that includes lip sync.

Where a vendor prints no free allowance, we say so rather than estimate one. Magic Hour's dollar figure is the entry price its own page states, on yearly billing. Captions states that its prices reflect iOS plans only. We did not run any tool on test footage, so this page makes no quality claim.

Plan	Price	Best for
HeyGen Free	Free	3 videos a month, videos up to 1 min, limited trial access to lip-sync translation
HeyGen Creator	$29 a month, or $24 billed yearly	600 credits, videos up to 30 min, 1080p export, watermark removal
Magic Hour Free	Free	Free daily credits; free video and audio outputs may carry a watermark
Magic Hour plans	From $12 a month on yearly billing	Watermark removed on paid plans and credit packs; packs at $1 for 400 credits
LatentSync	Free, Apache-2.0	Open-source code you run yourself, with 8 GB of VRAM as the inference minimum
Wav2Lip	Free, non-commercial	Personal and research use only; commercial requests routed to Sync Labs
Kapwing Free	Free	10 credits, exports with a watermark, up to 4 minutes per export, no lip sync
Kapwing Business	$50 a month, billed yearly ($64 billed monthly)	4,000 credits a month, lip sync videos, custom voice clones
Captions Free	Free	Basic tools such as trimming and transitions, with no AI usage credits
Captions Max	$24.99 a month	500 credits a month with AI features; the page's prices are for iOS plans
Sync Hobbyist	$5 a month plus $0.05 per second	Lip-synced videos up to 1 min, one job at a time
Sync Creator	$19 a month plus $0.05 per second	Videos up to 5 min, no watermark

Mistakes to avoid

×Treating a free plan as a production plan. Kapwing's free exports keep its watermark and Magic Hour's free video may carry one, so a client clip needs a paid tier.

×Counting credits as minutes. The pricing pages we read do not state the credit cost of one lip sync, so a budget built on minutes will miss.

×Assuming open source means free to sell. Wav2Lip's repository bars commercial use, while LatentSync's Apache-2.0 license allows it. Read the license before a client job.

×Buying a monthly plan without checking the yearly price. Kapwing Business is $64 a month billed monthly and $50 billed yearly.

×Judging lip sync by a demo gallery. None of these pricing pages proves output quality, so run one clip of your own footage before you pay for a year.

Expert tips

→Start with HeyGen's free plan to test lip-sync translation on one real clip. Then decide whether the Creator plan is worth it for your volume. Our <a href="/reviews/best-free-ai-avatar-generators">free avatar generators guide</a> covers the other side of that choice.

→For a free route that renews, test Magic Hour's daily credits, then check the watermark on the first export before you rely on it.

→If you have a GPU, LatentSync is free under Apache-2.0, so check your card against its VRAM minimum first.

→Price a batch on Sync's meter. At $0.05 a second, a 10-minute batch is 600 seconds, or $30 of usage, on top of the Hobbyist plan fee.

→Keep the original file and the license terms with each output, so a watermark or rights question can be answered later.

The bottom line

For a free test with lip-sync translation, start with HeyGen, whose free plan has a monthly video cap. For a free allowance that renews each day, try Magic Hour, and check whether its free outputs carry a watermark before you use one.

If you own a GPU, LatentSync is the free option here with a clear commercial-use license.

Pay for any lip sync tool only after you have checked the watermark rule on your own output.

Keep going with our AI subtitle generators guide and our free transcription tools guide if your video work starts with captions.

Frequently asked questions

What is the best free AI lip sync tool in 2026?

HeyGen, if you want a hosted tool: its free plan gives 3 videos a month up to one minute, with limited trial access to lip-sync translation, according to its pricing page checked on October 10, 2026. If you can run a GPU, LatentSync is free under Apache-2.0 and needs 8 GB of VRAM for inference.

Is there a free AI lip sync tool with no watermark?

Not on the hosted free plans we read. HeyGen lists watermark removal from its Creator plan, Magic Hour says free video and audio may carry a watermark, and Kapwing's free exports keep its watermark. LatentSync and Wav2Lip are code you run yourself, so none of those hosted plan rules applies to them.

How much does lip sync cost on a paid plan?

Entry prices differ. Magic Hour starts at $12 a month on yearly billing, HeyGen Creator is $29 a month or $24 billed yearly, Sync starts at $5 a month plus per-second usage, and Kapwing's lip sync sits on its Business plan at $50 a month billed yearly.

Can I use free lip sync output for client work?

Check the terms before you invoice. LatentSync's Apache-2.0 license allows commercial use under its terms, while Wav2Lip's repository prohibits it. For the hosted tools, the free-plan pages we read did not state commercial rights, so read the terms of the plan you actually use.

Is Kapwing free for lip sync?

No. Its Free plan has 10 credits and watermarked exports, and lip sync videos are listed only on the Business plan, which bills yearly at a lower rate.

Why is Hedra not on this list?

Hedra's pricing page is titled Free Plan, No Credit Card, but the plan table we read on October 10, 2026 starts at $20 a month and lists no free plan. Sync stays in because its entry card has a free-try button, while Hedra's table offers no free option at all.
