I built this because I wanted word-by-word captions for my own videos without paying a monthly subscription. It started as a simple transcription tool and grew into a full captioning workflow with batch processing, a waveform timing editor, multiple caption styles, and burned-in video export, all running locally on your Mac.
No account. No cloud upload. Your footage never leaves your machine.
There’s a full 30-day Pro trial built into the app, no card required, so you can try everything before deciding. Happy to answer anything about how it works.
The fact that Quick Mode handles mixed codecs and resolutions in a single batch is a huge time saver, shows real thought about how messy real workflows actually are.
Ran it on a folder of mixed videos and the batch queue just worked without me having to pre-convert anything, which is rare. The word-by-word timing editor is impressively responsive for a local app.
