Free AI dubbing, compared

Free AI video translator: what is really free, and what DubSync costs.

Dubbing that costs you nothing is built into YouTube and into Meta's apps, and it stays there: YouTube's automatic dubbing, whose help page lists no fee,1 and Meta AI translation for Reels, which Meta says is free.2 DubSync is not free. It is a paid tool, priced per input minute, with plans from $4.90 a month, and it returns a dubbed MP4 you post wherever you like. Below: what each free option covers, what DubSync costs and how to test it on a short clip.

Upload a short clip

Pro: 7 days free for eligible new subscribers, with 60 minutes. Card required. Then $29.90/month; cancel before the trial ends to pay nothing. Trial minutes expire after 7 days.

Upload an MP4, MOV or M4V. You see the minutes and the cost before anything starts.

The short answer

Three ways to translate a video without paying for a tool.

Two of these dub the video, and each stays on its own platform. The third gives viewers text to read instead of a voice. If one of them covers your video, use it and keep your money.

  • YouTube automatic dubbing

    • No fee listed
    • Videos on your channel
    • An audio track on YouTube

    YouTube generates translated audio tracks for videos on your channel and marks them as auto-dubbed in the description. The feature is switched on by default for eligible creators, and YouTube's help page lists no fee for it.1 In February 2026 YouTube said it was available to everyone, in 27 languages.3

    It dubs from English into a set list of languages, and from other supported languages mostly into English. A video over 120 minutes, with very little speech or with copyrighted content may get no dub. YouTube says automatic dubs can contain errors. You can review one before it is published, and unpublish or delete it later.1

  • Meta AI translation for Reels

    • Free
    • Facebook and Instagram
    • Plays on the reel

    Meta AI translates and dubs a reel in a voice that mimics the creator's, with optional lip-sync, and shows viewers that the reel was translated with Meta AI. Meta says it is free for Facebook creators with 1,000 or more followers and for all public Instagram accounts, in countries where Meta AI is available.2

    Meta opened it to creators in August 2025 with English and Spanish. Hindi and Portuguese followed that October, and updates to the same post in 2026 list more languages, not all of them on both apps.2 Meta's guidance for creators says that on Facebook the tool supports up to two speakers, and that translations work best with face-to-camera videos.4

  • Subtitles you add yourself

    • Text, not a voice
    • Added in YouTube Studio
    • Viewers read along

    If your viewers are willing to read, subtitles may be enough. On YouTube you add a language under Subtitles in Studio, then upload a subtitle file or type the text.5

    YouTube's automatic captions are a transcript, not a translation: speech recognition creates them in the video's default language only,5 and YouTube warns that accents, dialects and background noise can make them wrong.6 DubSync doesn't make subtitles or captions at all.

Free plans of other tools

What to check before you rely on a free plan.

Outside the platforms, every minute a tool processes costs its maker computing time, so expect a free plan to come with limits. Treat it as a sample until its terms say otherwise, and check six things before you plan a channel around it.

  • A logo on the video

    Is the export stamped with the tool's logo? That is fine for a test and awkward on your channel.

  • Length per video

    How long can one upload be? A cap of a minute or two shows how a short clip sounds, not a whole lesson.

  • Minutes per month

    How much can you process, and does the allowance come back next month or is it a one-time gift?

  • The download

    Can you download the finished file, or only preview it? At what resolution?

  • Commercial use

    Do the terms let you monetize the result or run it as an ad while you are on the free plan?

  • What happens next

    Is a card required? Does the free period turn into a paid subscription by itself, and on which date?

Free or paid

When free is enough, and when paying makes sense.

Free is enough when

  • Your videos live on YouTube only, YouTube offers your language pair and someone who speaks the language says the automatic dub sounds right.1
  • You post Reels on Facebook or Instagram, your account qualifies and Meta supports your language.2
  • Your viewers are happy to read, and you have translated subtitles to add.
  • You only want to hear what AI dubbing sounds like. Play the demo clips on this site, or try a free plan of another tool.

Paying makes sense when

  • You need a file: one dubbed MP4 for TikTok, a course platform, an ad account, your own site, or several of these at once.
  • The platform tool doesn't cover your case: a language pair it doesn't offer, a video over YouTube's 120-minute limit for automatic dubbing, or an account that isn't eligible.1
  • You want the same dub everywhere: one file, with a voice created from each speaker, on every platform where you post it.
  • You want to put your own dub on the platform. YouTube lets creators with access to advanced features add an audio-only track to a video,7 and a Facebook Page can upload its own dubbed audio tracks to a reel.4 DubSync returns an MP4, so export the audio from it in an editor first.

What DubSync costs

No free plan. A price per input minute, shown before you pay.

An input minute is a minute of your original video. You pay for the length of what you upload, once for each target language. There are two monthly plans, from $4.90 a month, and a one-time pack.

Current prices

Minutes Pack

Input minutes, bought once.
  • You upload first. DubSync shows the minutes your video needs and what they cost, and the dub starts only after you confirm.
  • Usage is counted to the second. A 45-second clip uses 45 seconds of your minutes.
  • Each target language is its own project and uses the video's minutes again: a five-minute video dubbed into Spanish and into German uses ten input minutes. Downloading a finished MP4 again uses none.
  • Monthly minutes renew each billing cycle and don't roll over. Minutes from a pack don't expire.
  • Lip-sync is not included. It is an optional add-on for a finished dub, priced per minute and paid from its own prepaid balance, with a quote before it starts.
  • What the minutes buy: a dubbed MP4, a voice created from each original speaker, your background audio kept and no visible watermark.

Before you pay

Hear a finished dub before you pay anything.

Three things to listen for

Every clip on this site is an AI-generated scene with a fictional character, dubbed with the dubbing model the app runs. None of them is a customer video. Play the original, then pick a language under the player.

  • The voice. It is created from the original speaker, so it should sound similar, not identical.
  • The background. Whatever sits under the speech in the original is kept in the dub.
  • The lips. A track marked lip-synced shows the optional paid add-on; the other dubbed tracks are the dub alone.

A demo shows how the model sounds, not how your microphone, your accent or your music will come through. For that, test a clip of your own. More clips, sorted by kind of video, are on the examples page.

A cheap test

Try DubSync on one short clip before you pay for a long video.

  1. Cut 30 to 60 seconds

    Pick the hardest part of your video, not the easiest: names, numbers, fast speech, music under the voice. Export it as MP4, MOV or M4V.

  2. Upload it and read the numbers

    Sign in and upload the clip. The spoken language is detected for you. Choose one of 28 target languages and read the minutes the clip needs and what they cost. So far you have paid nothing.

  3. Take the smallest plan

    The Creator plan includes 10 input minutes per billing cycle: one short clip in several languages, or several clips in one. It is a monthly subscription that renews until you cancel, so read the renewal and cancellation terms at checkout. If you would rather not subscribe, the Minutes Pack is a one-time purchase.

  4. Watch it like a viewer

    Sit down with someone who speaks the language. Does the voice sound similar to the speaker? Are the names and numbers right? Is the music still there under the speech? There is no script editing, so what you hear is what you would publish.

  5. Decide with the cost in front of you

    If the clip passes, upload the full video, up to 150 minutes and 1 GB, and read its quote before you confirm. If it doesn't, you have paid for the smallest plan, not for a long video. Cancel the subscription if you don't want it to renew.

Before you upload

Free or paid, translate only what is yours.

If the video is someone else's, the price of the tool isn't the question. To watch it, you need no dubbing tool: on YouTube, viewers can switch between a video's original and dubbed audio tracks.1 To dub and repost it, you need the owner's permission and the consent of everyone who speaks in it, whatever the tool costs.

Questions

Questions before you start

Is DubSync free?

No. There is no free plan. DubSync is paid per input minute, which is the length of your original video, for each target language. You can upload a video and see the minutes and the cost before you pay anything.

Is YouTube's automatic dubbing really free?

As far as YouTube's own help page goes, yes: it lists no fee, and the feature is switched on by default for eligible creators.1 The limits are elsewhere: it dubs videos on your own channel, in the language pairs YouTube supports, and the dub is an audio track on that YouTube video.

Is there a free AI video translator without a watermark?

The platform tools mark a dub with a label. YouTube marks automatic dubs as auto-dubbed in the video description,1 and Meta labels a translated reel as translated with Meta AI.2 Both play on the platform itself, and neither page describes a file to download. For a tool that gives you a file, check the free plan for a stamped logo and a length cap first. DubSync's MP4 has no visible watermark, but DubSync is a paid tool.

Can I try DubSync before paying for a long video?

You can keep the test small. Cut a clip of 30 to 60 seconds, upload it and read the quote. Seeing the quote costs nothing; the dub itself needs a plan or a pack. Usage is counted to the second, so a short clip uses a small part of the Creator plan's 10 input minutes. If a trial is on offer, its terms appear under the upload button at the top of this page and on the pricing page.

Is lip-sync free with a dub?

No. Lip-sync is an optional paid add-on for a finished dub. It is priced per minute and paid from its own prepaid balance, not from plan minutes, and you see the quote before it starts.

Can I translate a YouTube video for free by pasting its link?

Not in DubSync. It takes a video file (MP4, MOV or M4V) that you own or have licensed, not a link. If you only want to understand a video, switch to its dubbed audio track on YouTube, where one exists.1
