Entirely on your Mac, using on-device Whisper speech recognition (accelerated by Apple Metal). Your audio and video files never leave your computer.
Transcription runs locally using a Whisper model. Open Settings → Models and download a model once (from Hugging Face or ModelScope, your choice). Smaller models are faster; larger models are more accurate.
Use a larger model (e.g. Large) and, if needed, pick the correct language in the transcript header instead of Auto Detect.
SRT, VTT, and ASS — ready for YouTube, Premiere Pro, Final Cut, and most editors and players.
Yes. Everything stays on your Mac. The app collects nothing and uploads nothing; the network is used only to download the model you choose. See our Privacy Policy.

全程在你的 Mac 本地完成,使用本地运行的 Whisper 语音识别(由 Apple Metal 加速)。你的音视频文件从不离开电脑。
转写在本地用 Whisper 模型完成。打开 设置 → Models,下载一个模型即可(来源可选 Hugging Face 或 ModelScope)。小模型更快,大模型更准。
使用更大的模型(如 Large);必要时在字幕头部把语言从 Auto Detect 改成对应的语种。
SRT、VTT、ASS —— 可直接用于 YouTube、Premiere Pro、Final Cut 等绝大多数编辑器和播放器。
安全。一切都留在你的 Mac 上。应用不收集、不上传任何数据;网络仅用于下载你选择的模型。详见隐私政策。
