How GameStar expands to a global gaming audience with Dubly.AI — without leaving its original channel

GameStar is the largest online video magazine for gaming in the German-speaking world — with over 1 million YouTube subscribers and a passionate community that follows reviews, news, and in-depth analysis of games and pop culture. Until now, the channel was exclusively in German — leaving out potential international viewers.

The goal: to offer content in multiple languages without building new channels or compromising editorial tone. At the same time, the personal style of the hosts had to be preserved — without creating the impression of a generic voice-over.

With Dubly.AI, GameStar has implemented seamless localization of its content — authentic, on-brand, and directly on its existing YouTube channel. Thanks to Multi-Language Audio, viewers can now switch between German and English with a single click — without ever leaving the video.

And it’s more than just dubbing: using voice cloning and lip sync, the hosts’ voices, tone, and personalities are preserved — simply in the target language. Editorial control remains with the GameStar team, while Native Speaker Control ensures that gaming terminology and community tone are translated with precision.

With Dubly.AI, GameStar is reaching an international audience for the first time — directly on its main channel, with no detours and no need for additional productions.

Initial English-language videos are already showing significantly increased viewership from abroad — a clear sign that the concept is working.

For the editorial team, this means: no duplicate channels, no generic voiceovers — just an authentic entry into the global market, with the voices, faces, and content that define GameStar.
