Whoa, I’m honestly blown away by this thing.
Stumbled across a local tool called KrillinAI. It’s free, and handles video translation, precise subtitles, ultra-natural voiceover, and voice cloning — the entire pipeline in one go.
Chinese–English translation is rock solid, Whisper’s recognition accuracy is ridiculously high, The LLM translates segment by segment without losing context, CosyVoice’s TTS sounds almost like a real person speaking. Supports Windows and Mac, ready to use after download, and you can pull videos straight from YouTube with yt-dlp or upload local files. Auto-adapts to landscape and portrait. If you create content for overseas audiences, you can genuinely use this as-is.
Before, translating a video meant juggling CapCut and all kinds of plugins. Now one tool handles everything — subtitle alignment is clean, and the voiceover naturalness exceeds expectations. Free, runs locally, no watermark.
