#4 of 33 in Dubbing and voice
A video localization tool that translates, voice-clones and lip-syncs the videos you already made into 80+ languages, billed per minute
Best for: Creators, course makers and marketing teams who already have strong on-camera videos and want them in other languages with their own voice and matching lip movement.
#5 of 33 in Dubbing and voice
A lip-sync and visual dubbing platform from sync. labs, running its own sync-3, lipsync-2-pro and react-1 models in a web Studio, an API and editor plugins
Best for: Editors, localization teams and developers who already have footage and new audio, and need the mouth to match it convincingly.
The short answer
More creators choose LipDub AI than sync., and it ranks higher in our dubbing and voice list. Pick LipDub AI if you want creators, course makers and marketing teams who already have strong on-camera videos and want them in other languages with their own voice and matching lip movement. Pick sync. if you want editors, localization teams and developers who already have footage and new audio, and need the mouth to match it convincingly.
LipDub AI: A focused localization tool that does one job, dubbing and lip-syncing real footage, and publishes its per-minute rates in full. There is no free plan to test on, the plan fee comes on top of usage, and monthly credits expire after 60 days, so it suits steady localization work more than a one-off experiment.
sync.: A specialist lip-sync engine with its own models, real editor plugins and a public API, priced per second so you pay for what you render. It does not make videos from scratch, the subscription-plus-usage billing takes some reading, and the free allowance and language count differ depending on which sync. page you read.

Strengths and weaknesses
LipDub AI
- Per-minute rates are published for every plan, so you can budget before you sign up
- Lip sync is included from the $29 entry plan, not locked to a top tier
- Dubbing-only mode costs about half as much as lip sync for videos where the mouth is not on screen
- Unlimited seats and parallel jobs on every plan
- Works on live-action, animated and AI avatar footage, per LipDub
- Credits for failed generations and failed speaker training are refunded automatically
- No free plan on the pricing page, despite "try free" in the site description
- You pay the plan fee and per-minute usage, so the sticker price is not the real cost
- Uploading your own audio is not available on the $29 Core plan
- Monthly-plan credits expire 60 days after purchase, and no refunds on subscriptions
- Premium and Ultra models add a one-time training fee per speaker that the pricing page does not price
- Video length limits conflict: the plan table says 10 to 120 minutes, the FAQ says up to 180 minutes per video
- No mobile app and no built-in editor for cutting the video itself
sync.
- Runs its own lip-sync models rather than reselling someone else's
- Pay per second of output, so short jobs stay cheap
- Works inside Premiere Pro and DaVinci Resolve, not only in a browser
- Public per-second and per-frame rates for every model
- Several model tiers let you trade cost for quality shot by shot
- Clear refund rule on the two cheapest plans if you have barely used them
- Two bills: a monthly fee plus usage invoices whenever usage hits a threshold
- Hobbyist still watermarks output; clean exports start at $19 a month plus usage
- The pricing page shows no free plan, while the docs describe a monthly free allowance
- Dubbing languages are listed as 29 on the pricing page and 92 in the latest changelog
- It only re-syncs existing faces; you need footage or a photo and audio from elsewhere
- Some accounts are moved to a separate credit plan with different names and limits
