Merge two SRT tracks into bilingual subtitles
Paste a primary and a secondary SRT track and combine each cue into one bilingual subtitle — everything runs locally.
Both inputs should be SRT with the same cues and timing; the primary track supplies the timestamps.

- Cues are merged by position: the first cue of each track is combined, then the second, and so on, using the primary track timing.
- What if the tracks have a different number of cues?
- They are merged up to the shorter track and a mismatch notice is shown so you can review the result.
- Does it upload my subtitles?
- No. Everything runs locally in your browser.
