The Key Difference
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.
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.

Johann
"Dubly.AI has been a huge help in translating my video content into another language (Spanish). I do speak Spanish myself, but the tool saves me a massive amount of time. The results are great. A clear recommendation from me. If you're unsure — just give it a try!"
Sonne Frei Haus
"With Dubly.AI, we're able to reach a broad international audience with just one video. The translation works brilliantly, and even the voice is reproduced 1:1. Truly impressive! 100% recommended!"
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."
