Fix subtitle files, or turn audio into an SRT
Drop in an SRT or a VTT and fix it in your browser — or upload audio or video and get an SRT file made from the speech itself, paid per file and never by subscription.
The toolkit runs entirely on this page: those files are never uploaded anywhere. Audio sent for transcription is transcribed and dropped — never stored, and never used for anything else.

Audio to SRT: captions from the speech

What it does
Turns audio and video into an SRT file
Generate subtitles from audio: upload an MP3, M4A, WAV or MP4 recording and get timed captions made from the speech, ready to check and download as SRT, WebVTT or plain text. The first 30 seconds are free with no account. A whole file is paid in minutes from a one-off pack — no subscription, no monthly plan, and the minutes never expire — so one interview or one lecture costs what it takes and nothing more.
Converts between the formats
SRT is what editing software and most players expect. WebVTT is what a browser needs for the <track> element, and it is what a handful of upload forms insist on. They hold the same information and differ over a comma. Paste one, pick the other, done — and plain text is there too, for when you only wanted the words.
Puts the timings back in sync
If the subtitles are late by the same amount all the way through, shift them. If they start right and drift further out the longer the video runs, that is almost always a framerate mismatch — film shot at 23.976 frames per second, captions cut against 25 — and a single multiplier fixes the whole file at once.
Turns a transcript into captions
Paste the text a dictation tool gave you and CaptionIt breaks it into caption-sized pieces, prefers to end each one at a full stop rather than mid-clause, and gives every piece enough time on screen to actually be read. The speaker labels and the tool's own timestamps are stripped on the way in.
Tidies up what the last tool left behind
Styling tags nobody asked for, captions that overlap the next one, lines so long they wrap by themselves in the middle of a word. CaptionIt can strip the markup, pull overlapping captions apart, and re-wrap every line to a length that reads cleanly on a phone.
Minutes for transcription
The toolkit is free and always will be. Minutes are only for turning speech into words, which costs us real money to run.

The guides
Short, specific write-ups for the problems people arrive here with — why an SRT file refuses to load, how far to shift a subtitle track, how many characters a line should hold before it stops being readable.
