See how a developer API compares to an end-to-end video dubbing solution.
Sync Labs
Last updated: 05.03.2026
Sync Labs is an API. Dubly.AI is a complete platform.
Sync Labs provides lip sync as a developer API — a building block you integrate into your own pipeline. Translation, voice cloning, video processing, and user interface must all be built separately. Dubly.AI delivers everything in one platform: upload a video, select your target language, and get a fully dubbed video with industry-leading lip sync (96.4 score) — no development required.
Your company needs to translate 50 training videos into 3 languages. With Sync Labs, you need a development team to build the entire pipeline: translation API, voice cloning integration, video processing, and a review interface — months of development time and ongoing maintenance. With Dubly.AI, your content team uploads the videos, selects the languages, and gets professionally dubbed videos with lip sync the same day.
Same video. Same speaker. Different technology.
Dubly (right) translates your real footage. Watch identical scenes and see why Lip Sync 2.0 scores 96.4 vs. Sync Labs' variable API quality.
Instant results. No credit card needed.

"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."
