Output

First file free (up to 150 cues). 1 credit = 1 file × 1 language.

Drop your .smi file below, choose the languages, and download a translated .smi that plays in perfect sync. The file is parsed in your browser; only the cue text is sent for translation.

What stays untouched

The <SAMI> header with its class definitions, <SYNC Start=…> timings and <P Class=…> attributes are rebuilt as they were; <br> line breaks inside cues are preserved.

Tip

Most modern platforms want SRT. If you need SRT instead of SMI, translate here and convert afterwards — the timings map one to one.

Why not paste into a chatbot

Chat tools reflow timecodes, drop cue numbers and merge lines. Here each cue is translated with the previous cues as context and written back into the original structure, so nothing drifts.
