Papercup – Media-Centered Solution
Papercup provides automatic voice-over and is strong in the news & media sector.

Synthesia – Avatar-First Platform
Synthesia is globally known for AI avatars. Videos can be generated in minutes with synthetic voices.

Why Data Privacy Matters Most
Especially in Europe, data privacy is non-negotiable.
- U.S. providers like HeyGen or Synthesia often process data outside the EU.
- Dubly.AI guarantees maximum data security: no customer data used for training, 100% GDPR compliance, European servers only.
This makes Dubly.AI the safe option for industries like media, education, or automotive where sensitive content must stay protected.

Examples include e-learning, internal training, marketing videos, social media content, HR training, and international communication.

While U.S. providers focus heavily on avatars, Dubly.AI offers realistic Lip Sync, original voices in other languages, and strict GDPR compliance.

✅ Checklist for the right provider
- Do you need realistic Lip Sync instead of artificial voice-over?
- Is data privacy and GDPR compliance important to your company?
- Do you require enterprise features like API or bulk translation?
- Do you want to keep your original voice in other languages?
- Is human quality control (NSC) critical for sensitive content?
If the answer is yes, Dubly.AI is the clear solution.
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.
