Two very different needs
Before choosing a tool, clarify your goal. If you just want understand a video in English you watch, you don't need dubbing software: a browser extension or translated subtitles do business, in seconds and without paying. If you are creator and that you want to publish your video in several languages with a real voice (and ideally the synchronization of lips), there you need a tool of the dubbing AI. These are two worlds, we treat them separately.
Translating a video you watch (free methods)
To put an English video in French the time to watch it, three free options:
- Translational subtitles YouTube : enable subtitles (CC icon), then in the settings, « Subtitles » then « Automatically translate » and choose French. Seeofficial aid YouTube.
- Automatic dubbing YouTube : more and more channels activate multilingual audio. If so, change the audio track in the video settings.
- Browser extension : several extensions translate subtitles and audio on the fly, including voice dubbing, directly on YouTube.
💡 Tip: on phone, application YouTube already offers automatically translated subtitles. For full voice dubbing on mobile, go through a tool online rather than an extension.
Double and translate your own video with AI
That's where IAI changes the deal for creators. In a few minutes, you transform a French video into an English, Spanish or Japanese version, with a natural voice and synchronized lips. Three tools dominate in 2026.
HeyGen : most complete (labial synchronization)
HeyGen is the reference of video dubbing. It translates into more than 175 languages, clones your voice and resynchronizes the movement of the lips for a bluffing rendering. The free plan allows you to translate up to three videos per month (3 minutes each), subtitles and voiceover included. For regular production and unlimited labial synchronization, count about 24 to 29 $ per month. We detail everything in our complete test of HeyGen.
ElevenLabs Dubbing: the best voice
ElevenLabs focus on audio, and that's its strength: voice quality is the best in the market, in about thirty languages, with preservation of tone. Ideal if labial synchronization is not your priority (podcasts, voiceover, audio content). The free plan offers a sufficient monthly quota to test. More info in our review ElevenLabs.
Rask AI: language coverage
Rask AI covers more than 130 languages and offers a free trial (a few minutes of dubbing on registration) to judge the quality. Labial synchronization is reserved for high plans, more expensive than competition. A good option if you target rare languages not covered elsewhere.
Comparison of the tools video translation

Video demonstration is more meaningful than any text:
Free or fee: what to choose?
To watch a translated video, stay on the free: subtitles YouTube, auto dubbing or extension is sufficient. To double your own content, free plans allow you to test (a few short videos), but quickly impose their limits: duration, watermark, number of languages, and especially the labial synchronization often reserved for the payer. As soon as dubbing becomes a growth channel, subscription (around 20-30) $ per month) is profitable by the internationally won hearing.
