WhisperGo turns your videos into subtitled videos. Pick a video and shortly get an MP4 with subtitles burned in. Speech recognition, alignment, editing and export all happen on your device: no upload, no account, and the built-in model works offline. AUTOMATIC SUBTITLES • Manually choose from the model’s languages, including Chinese, English, Japanese, Korean, French, Spanish and Vietnamese, or use automatic detection • Word-level timing keeps every line in step with the speaker • Have a script? WhisperGo uses it word for word, and recognition only provides the timing • Four strength levels: Fast, Balanced (built in, works offline), Accurate, and Maximum (Mac and M-series iPad) FINE-TUNE EVERY LINE • Drag in and out points on the timeline, or nudge them by 0.1 seconds • Split at any word, merge with the line above or below, undo and redo • Clean up sentence-end punctuation while keeping question and exclamation marks STYLE WHAT YOU SEE • Font size, outline, color and a translucent background box • Snap to a 3×3 grid or drag subtitles anywhere on the frame; position single lines on their own • Preview and export share one renderer, so the video you export matches the preview EXPORT • MP4 with burned-in subtitles: save to Photos or share • SRT and ASS subtitle files plus timeline JSON • Audio files (MP3, M4A, WAV) become SRT, timestamped text and JSON MORE ON MAC • Two-pane home: drop a video into the window and start • Batch-process a whole folder • Full menus and keyboard shortcuts SHORTCUTS • A "Generate Subtitles" action for your automations on iPhone, iPad and Mac PRIVACY WhisperGo collects no data. The only network request happens when you choose to download a stronger model: the public model files come from Hugging Face, and the request contains none of your content. ## Is WhisperGo safe?
