What SubtitleFlow is
SubtitleFlow is a web service for creating timed subtitles from audio or video and translating subtitle files. It handles SRT and VTT subtitles, MP3, WAV, and M4A audio, plus MP4, MOV, and WebM video. Translations retain cue timing, including sentences spanning multiple cues. The editor offers side-by-side source and translation review, waveform scrubbing, find-and-replace, a glossary, and bulk edits. Exports include SRT, VTT, TXT, PDF, and DOCX. Bilingual output can place the original above the translation or provide translation only. Captions are not burned into video. The free tier previews opening subtitle lines or the first two minutes; full files require paid plans or credit top-ups. Pricing includes Pay as you go at $5 a month, Standard at $9.99 a month, and Plus at $19.99 a month.
