Dubly.AI vs HeyGen
Dubly.AI and HeyGen are often compared, but they solve fundamentally different problems. Dubly.AI is a video dubbing & translation platform built for enterprise video translation. HeyGen focuses on ai avatars & video creation, making it a better fit for ai avatar videos. We tested both platforms to break down where each one excels and where it falls short.
The Key Difference
HeyGen is an avatar-first platform that added video translation as a secondary feature. Dubly.AI is purpose-built for dubbing real footage. This architectural difference shows up everywhere: Dubly.AI's lip sync is optimized for real human faces and natural speech patterns, while HeyGen's lip sync engine was designed for synthetic avatars and can struggle with occlusions, rapid movement, and complex real-world footage.
Feature Comparison
When comparing features, pay attention to more than just checkboxes. Dubly.AI supports 32+ languages and HeyGen offers 175+ — but raw language count is less important than quality in your target languages. Look at lip sync ratings, multi-speaker handling, and whether the platform produces finished video or just audio tracks.

Pricing
Pricing in the AI dubbing space is notoriously hard to compare apples-to-apples. Dubly.AI uses a credit-based model starting at €79/month, while HeyGen charges via tier-based + seats starting at $29/month. The real cost depends on your volume, whether you need lip sync (which often costs extra), and how many team members need access.

Data Privacy & Compliance
Both platforms process data on EU servers, but the details differ. Look at the specific server location, whether a Data Processing Agreement is available, and crucially, whether the provider trains its AI models on your content. For regulated industries and European businesses, these distinctions can be deal-breakers.
