Subtitle QC Checker
Subtitle QC Checker helps you upload or paste SRT and VTT captions, then spot cues that are too fast to read, poorly timed, or overlapping. Review results against common streaming presets, auto-extend safe gaps, and download adjusted captions plus a QC report. An optional AI Assistant can compare cues with a dialogue transcript or media check when you explicitly run it; paid bulk QC can process multiple subtitle files into one ZIP.
