## What it is
Subtitle Edit is a free, open-source desktop application for creating, editing, converting, and synchronizing subtitles, with video playback via mpv/ffmpeg. It also offers optional speech-to-text, text-to-speech, OCR, and translation integrations, running fully offline for core features.

## Use cases
- edit srt subtitle files
- sync subtitles to video timing
- convert subtitles between formats
- auto-generate subtitles from audio speech to text
- ocr subtitles from a hardcoded video
- translate subtitle files to another language
- fix subtitle line breaks and spelling

## When to choose
- you need a full-featured GUI subtitle editor on Windows, macOS, or Linux
- you want offline subtitle editing with local auto-backup and privacy
- you need format conversion, waveform sync, or speech-to-text in one tool

## When to avoid
- you need programmatic subtitle processing in a script or CI pipeline
- you want a web-based or collaborative subtitle editor
- you only need a lightweight command-line converter
