#9 of 33 in Dubbing and voice

Dub AI homepage headline about translating videos in minutes

A focused web tool that translates and dubs video or audio into 40+ languages, keeps each speaker's voice, and hands you the transcript, subtitles and audio files

Best for: YouTubers, course makers and small teams who want to dub a finished video into another language in their own voice, without a full editor or a subscription.

The short answer

More creators choose sync. than Dub AI, and it ranks higher in our dubbing and voice list. 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. Pick Dub AI if you want youtubers, course makers and small teams who want to dub a finished video into another language in their own voice, without a full editor or a subscription.

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.

Dub AI: Simple, cheap to try and easy to budget, with a one-time credit pack and useful exports. It skips lip sync and editing tools, publishes no API docs and names no model provider, so it suits occasional dubbing more than a localization pipeline.

Strengths and weaknesses

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

Dub AI

  • Free minute with no card, so you can test your own voice first
  • One credit equals one second, the simplest pricing in this category
  • A one-time $15 pack means no subscription for occasional jobs
  • Subtitle, transcript and audio stems come with every dub
  • Clear consent and review guidance on its own pages
  • Says voice data is not kept after dubbing or used for training
  • No lip sync, so on-camera talking heads will look out of step
  • No published API documentation; API needs a sales conversation
  • Only one monthly plan, and it jumps straight to $60
  • Does not say which voice or translation models it uses
  • Testimonials are mostly first names and handles, hard to verify
  • Only 1 concurrent job on the pay-as-you-go pack
