Other sites may work when they play a plain video file, but players streaming video in small pieces are unsupported. Chrome, Edge, Brave, Firefox, Firefox for Android, and Quetta Browser are supported; Safari and iOS are not. The Free plan is free, while Basic is €5 a month including VAT and adds unlimited dubbing, 322 voices, subtitle-free video dubbing, summaries, chapters, and email support. Free-use limits differ between the pricing and Terms pages.

Linly-Dubbing is an open-source tool for translating and dubbing videos into Chinese and other languages. It combines speech recognition and speaker recognition with translation options using OpenAI models, locally run Qwen, or Google Translate. Documented voice synthesis choices include Edge TTS, XTTS, CosyVoice, and GPT-SoVITS; voice cloning can generate speech resembling the original video's voice. Linly-Talker lip-sync technology aligns dubbed speech with the video. The tool can add subtitles and background music, adjust music volume, change playback speed, separate vocals from accompaniment, and download video and audio through yt-dlp. Setup instructions describe a local WebUI and use of Python 3.10, PyTorch 2.3.1, and CUDA 11.8 or 12.1, with Windows and Linux model-download instructions. A Colab script is also linked for online use. Installation requires configuring dependencies, downloading models, and setting environment variables, and may use external service credentials depending on configuration.
