Overlong captions become readable two-liners with one action. The reading-speed hints are a nice touch.
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.
Imported an old SRT that drifted badly. Retimed the whole thing in one evening, in a browser.
Every SRT I’ve exported has uploaded to YouTube and Vimeo without a single validation error.
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.

Yes — break overlong lines into readable pieces or merge fragments into one caption, so reading speed stays comfortable for viewers.
No — exports are standards-compliant SRT/VTT with valid timestamps and encoding, accepted by YouTube, Vimeo, LMSs and editing suites.
