Why users love Sonix
Your app is amazing. Seriously, I'm blown away by the technology. The speed, accuracy, and the fact that you can play the audio and that it highlights the transcript in sync.
Having tried numerous transcription services, this was undoubtedly the best. There were features (such as the synching up of the audio to the words for review) that I hadn’t ever hoped to find.
