KrillinAI

Why we included this project

KrillinAI handles the whole video localization job in one place: it downloads a source video, transcribes the speech, translates the subtitles, generates a TTS dub, reformats the output for vertical or horizontal platforms, and even produces a cover image. The project supports more than 100 languages and is tuned for platforms like YouTube, TikTok, Douyin, and Bilibili. What makes it interesting is the two ways to drive it: a one-click client for people who just want the finished video, and a staged CLI that AI agents can call step by step to build their own automated workflows. So it works as well for a solo creator localizing a handful of clips as for a media team folding translation into a larger content operation. Instead of stitching together separate transcription, translation, and dubbing services, you get one configurable system.
