HeyGen builds avatars. Dubly.AI dubs real videos.
HeyGen was developed as an avatar platform. Video translation is an add-on feature, not a core product. Dubly.AI was built from the ground up specifically for video dubbing — with its own Lip Sync 2.0 model that scores 96.4 out of 100 in independent tests (HeyGen: 76.8). For companies that need a specialized AI video translator, the difference is immediately visible.
Your marketing team has 50 product videos featuring real employees, recorded in German. These need to be translated for the US market, France, and Spain — with perfect lip sync and the original speakers' voices. HeyGen can create avatars, but to translate your real videos with maximum quality, you need a specialized dubbing tool. That is exactly what Dubly.AI was built for.
Same video. Same speaker. Different technology.
Dubly (right) translates your real footage. Watch identical scenes processed by both tools and see why Lip Sync 2.0 scores 96.4 vs. HeyGen's 76.8.
Instant results. No credit card needed.

Mallorca Agent
"Best tool on the market. At Durchgedreht Media, we use Dubly.AI as a translation solution for our clients. Everything works perfectly, the interface is very intuitive, and the pricing is fair! We highly recommend this tool."
Jan
"I tried Dubly.AI to translate a video — and I’m genuinely impressed! The translation was accurate and sounded natural — far better than I expected. Dubly.AI helped me make my content more accessible to others, so I can only recommend giving it a try!"
Fabian
"As a service provider for a large company, I was responsible for having several online courses translated. Initially, we planned to hire a voice actor, as I was quite skeptical about AI. But the test results were so convincing that we’ve now translated nearly 60 videos using Dubly."
Tobias
"I use the platform for voice-overs in other languages — and it works surprisingly well, especially compared to other providers offering similar services. In some languages like French, it’s clear that Dubly.AI really delivers great quality."
