## What it is
A free, browser-based batch subtitle translation tool for .srt, .ass, .vtt, and .lrc files that strips timing locally and sends only dialogue to translation engines, preserving timelines. It supports 120+ languages via 8 traditional translation APIs and 27 LLM providers, with a CLI for headless scripting.

## Use cases
- translate a whole season of srt subtitles in one batch
- create bilingual subtitles for youtube or language learning
- convert srt to vtt or ass while translating
- translate subtitles without breaking timecodes
- batch translate vtt files into multiple languages at once
- translate lrc lyrics files with ai
- keep subtitle translation private in the browser

## When to choose
- you need to translate many subtitle files at once without touching timing
- you want bilingual subtitle output with preserved alignment
- you prefer a privacy-focused tool that runs entirely in the browser
- you need support for many subtitle formats and multiple target languages in one pass

## When to avoid
- you need to translate video audio directly rather than existing subtitle files
- you require server-side or API-based subtitle translation pipelines
- you need subtitle editing features beyond translation, like syncing or styling
