Why bother with this page
Because it does the one thing you came for.
You have an MP3 of the whole conversation and someone needs it captioned. This page listens once and hands back timed cues.
◇
No nasty surprises
A heavily compressed MP3 blurs consonants, so unusual words and proper names are worth a second look before you publish.

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
MP3 → SRT, answered
01What if I just want the words, no timings?＋
Use the audio-to-text tool instead — same recording, plain readable transcript, no timestamps to trip over.
02Do pauses matter?＋
They help. Natural pauses are what tell it where one caption should end and the next should begin.
03Can I edit the file afterwards?＋
Yes. It is plain text — open, fix, save, done.
