Captions land exactly on the speech. I used to spend evenings nudging lines around by hand.

YouTube kept mangling our brand names. Now I fix them once in the editor and upload a clean SRT.
Uploaded a two-hour recording during lunch — the transcript was waiting before I finished my coffee. The accuracy genuinely surprised me.
Our legal team approved it because processing stays on EU infrastructure. That alone ruled out most of the competition.
Captions split where a human would split them. Viewers stopped complaining about walls of text.
Added captions to every short — average watch time rose noticeably within a month.
No card, no tricks — I tested real files before paying and upgraded a week later because the workflow stuck.
Had trouble with a huge file — support walked me through batch upload the same morning. Rare these days.
