.srt or .vtt — one file or many
⚠ This engine sends your subtitle text to the endpoint below (a third party). The on-device engines keep everything local.
Timestamps, cue numbers and positioning are preserved exactly — only the text is translated. The on-device AI engine runs a small language model in your browser with WebGPU (Chrome or Edge on desktop); the first run downloads the model once and caches it for next time, and translation then works offline. The built-in translator is lighter and also on-device but more literal. The API-key engine is optional and sends text to the endpoint you choose. Batch results download as a ZIP. Everything except the optional API engine runs entirely on your device.
