Dubly.AI vs. Rask AI: Which Provider Delivers the Best AI-Powered Video Translation?

What Does Rask AI Offer?
Rask AI is an international AI tool that can translate and dub videos into many languages. Its strengths lie in automatic transcription, fast processing, and a wide language range.
Strengths of Rask AI:
- ✅ Wide language support, fast results
- ✅ Simple workflow for creators and small teams
- ✅ Good for short-form content like social media clips
Weaknesses in professional dubbing:
- ❌ Translation accuracy is inconsistent, often lacking context
- ❌ Unnatural pacing and robotic voices
- ❌ Lip Sync is imprecise, often not realistic
- ❌ No glossary management or custom prompts for brand/technical terms
- ❌ Data privacy unclear, no explicit GDPR compliance, likely non-EU servers
For creators or quick translations, Rask can work. For businesses that need quality, realism, and compliance, it falls short.

HR and onboarding content

FAQ: Dubly.AI vs. Rask AI

Rask AI is fine for quick clips, but in terms of translation quality, realism, and privacy it is weaker compared to Dubly.AI.

Dubly.AI delivers much higher translation quality, realistic Lip Sync, GDPR compliance, and enterprise features that Rask AI does not offer.

Yes. Dubly.AI can replicate the original voice in other languages – a unique feature that preserves authenticity.

Conclusion: Dubly.AI Clearly Outperforms Rask AI
Rask AI may work for quick social media clips or creators who need simple translations. But when it comes to quality, realism, and compliance, it lacks critical features.
👉 Dubly.AI is the only truly professional solution that provides businesses with secure, realistic, and enterprise-ready video translation.
Does the Dubly.AI free trial include the Lipsync feature?
Yes. We believe you need to experience the full technology to understand its value. The free trial includes Generative Lipsync and Voice Cloning, not just simple audio translation.
Is there a difference between a standard "Video translater" and Dubly.AI?
Yes. A standard "Video translater" often only translates text or audio. Dubly.AI is a comprehensive AI solution that adapts the visuals (mouth movements) to the audio, creating a seamless experience.
Can I use Dubly.AI for long-form content?
Yes. While many free tools limit you to 60 seconds, Dubly’s engine is built for scale – from TikTok Shorts to hour-long corporate training modules.
Can I use translate video free tools to internationalize my content?
Yes, absolutely. Using free tools is a great starting point to test new markets without a budget. However, keep in mind that methods like subtitles or basic video translator apps usually only transfer information, not emotion. To truly internationalize your brand's personality and retain viewers, you will eventually need lipsync technology to ensure the audience feels connected to you, not just the text.
Does a free ai video translator work for all types of videos?
It works well for content where the speaker is not visible, such as screen recordings or faceless tutorials. However, for any video featuring a person speaking on camera, a standard tool often falls short. Because it lacks lipsync, the visual mismatch distracts the viewer. For content meant to build trust or emotion, you need a solution that adapts both the voice and the visuals.
Is there a free version of Dubly.AI?
You can translate your first video for free so you can validate the quality with your own files. We believe in letting you prove the value first.
Does this work for any language?
Our AI supports over 30 languages, covering the majority of global markets (English, Spanish, German, French, Japanese, Mandarin, etc.). The Lip Sync works universally across these languages.
How accurate is the translation?
AI translation is very good (95%+), but for critical content, context matters. That is why we offer Native Speaker Control (NSC) as an add-on, where humans review the AI's work. This combines the speed of software with the precision of a native speaker.
Can I automate this process?
Yes. For agencies, media houses, or companies with high volume, we offer an API. This allows you to integrate video translation directly into your content management workflow, removing manual upload steps entirely.
