Turn Any Audio or Video Into Ready-to-Use Subtitles
Generate broadcast-quality SRT and VTT captions from any recording, lecture, podcast, or movie. Industry-standard timing, two-line wrapping, and reading-speed limits, built in.
Captions That Actually Meet The Standard
Most auto-caption tools dump raw speech-to-text into an SRT file: lines too long to read, cues that flash by, no respect for how fast a human reads. TranscriptAI applies the same timed-text rules broadcasters use, so the captions you download are usable the moment they land.
- Export 8 formats in one click: SRT, WebVTT, ASS, SBV (YouTube), TTML (broadcast), LRC (synced lyrics), TXT & JSON
- Netflix/BBC rules baked in: max 42 characters per line, max 2 lines
- Reading-speed cap (20 characters per second) so no cue flashes by
- Minimum and maximum cue durations enforced (5/6s to 7s)
- Smart line-breaking at clauses, never mid-word, balanced two lines
- Optional speaker labels for closed-caption (CC) style output
How It Works
Upload Audio or Video
Drop an MP3, WAV, MP4 or paste a YouTube/Vimeo link. We transcribe it with timestamps.
Review & Edit
Check the transcript, fix any words, and translate to another language if you need a second caption track.
Download Subtitles
Export as .srt or .vtt: compliant timing and line-wrapping done for you. Upload straight to YouTube, Vimeo, or your editor.
From Recording to Captioned in Minutes
Whether you are captioning a 90-minute film, a weekly podcast, or a course module, doing it by hand is hours of tedious timing work. TranscriptAI does the transcription, segmentation, and timing. You just review and download.
