## What it is
SmartSub (妙幕) is a free, open-source cross-platform desktop application that provides an end-to-end subtitle and dubbing pipeline: speech-to-text transcription, subtitle translation, proofreading, AI dubbing with voice cloning, and subtitle burning into video. It runs local models (whisper.cpp, faster-whisper, FunASR, sherpa-onnx) offline with GPU acceleration and supports batch processing on Windows, macOS, and Linux.

## Use cases
- generate subtitles from a video automatically
- translate srt subtitles to another language
- transcribe podcast or lecture recordings to text
- add chinese subtitles to a youtube video
- dub a video into a foreign language with tts
- clone my own voice for video narration
- burn hardcoded subtitles into a video
- batch transcribe meeting recordings offline

## When to choose
- you need an all-in-one offline tool for subtitle generation, translation, dubbing, and burning
- privacy matters and you want files processed locally without API keys
- you want batch processing with GPU acceleration across Windows, macOS, and Linux
- you work heavily with Chinese content and want FunASR/FireRedASR engines

## When to avoid
- you need a programmatic library or CLI to embed transcription into your own pipeline
- you require professional-grade subtitle editing with advanced timing features found in dedicated editors like Aegisub
- you only need cloud-based transcription without downloading local models
