The Descript alternative that keeps your recording on your device
Descript's whole model depends on the media reaching its servers: that is where the transcript is made, where Studio Sound runs and where Underlord thinks. It is a fair trade for what you get back, but it is a trade, and it is not one everybody can make. Coaching sessions, client interviews and internal recordings are the obvious cases.
Montaj does the equivalent work in the other direction. WhisperKit transcribes on your device, the karaoke subtitles are built there, silence detection runs there and the neural denoiser runs there. Your video never leaves your device, and after the one-time model download the app does not need the network at all.
