Why bother with this page
Because it does the one thing you came for.
Captioning by hand is an hour of your life you do not get back. Send the recording over, let it listen, and get a subtitle file you only have to skim and tidy.
◇
No nasty surprises
Clear speech and a quiet room get you close to done. Give names, jargon and numbers a quick read before you publish — that is where machines still slip.

Nobody else sees it
Your upload is deleted the moment the job finishes. The result is private to you, disappears by itself after 24 hours, and you can wipe it sooner with one click.
Before you ask
AI subtitle generator, answered
01What do I actually get?＋
An SRT file: numbered cues with start and end times, the format YouTube, LinkedIn, Vimeo and every editor worth using will accept.
02Are the captions burned onto the picture?＋
No, and that is usually what you want — a separate file you can fix, translate or turn off. If you want captions styled and burned in, do that in the editor.
03How accurate is it?＋
Good enough that reading through beats typing from scratch every time. Accents, crosstalk and background noise are where you will want to make corrections.
