FAQ: HeyGen vs. Dubly.AI
Is Dubly.AI a good alternative to HeyGen?
Yes. While HeyGen is mainly designed for quick avatar videos, Dubly.AI delivers a professional-grade solution for businesses – with better Lip Sync, GDPR compliance, and enterprise-ready features.
Does Dubly.AI support small and mid-sized businesses (SMBs)?
Absolutely. Dubly.AI is not only for large enterprises – it’s the smartest choice for any company that values quality, security, and professional translations.
How is Dubly’s Lip Sync different from HeyGen’s?
Dubly generates Lip Sync at the very end of the workflow, ensuring natural and realistic synchronization. HeyGen’s earlier automated approach often looks less authentic.

Yes. Dubly.AI operates on European servers only, is fully GDPR-compliant, and does not use customer data to train general AI models.
Can I use the original speaker’s voice in other languages?
Yes, this is a unique feature of Dubly.AI. It preserves the authenticity of the speaker’s voice even in translated videos.
Does Dubly.AI offer human quality control?
Yes. With the premium Native Speaker Control (NSC) service, certified native speakers review translations within 72 hours, fine-tuning grammar, timing, and style.
Conclusion: Dubly.AI as the Best HeyGen Alternative
For companies seeking the highest quality, realistic Lip Sync, and GDPR-compliant processing, Dubly.AI is the clear winner.
While HeyGen may work for quick and simple content, Dubly.AI offers the most professional solution for AI-powered video translation in a business context.
✅ Dubly vs. HeyGen Checklist
- Data privacy: Dubly 100% GDPR-compliant – HeyGen not.
- Lip Sync quality: Dubly leads with its end-of-process Lip Sync.
- Original voice in foreign languages: available only with Dubly.
- Enterprise features: API, bulk processing, glossary management – lacking in HeyGen.
- Support: Dedicated German team, certified native speakers, tailored enterprise support.
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.
