What customers say about Sonix's automated transcription 
Thank you for this amazing application and program which really saved my life.
I absolutely love what you guys have done with this. Sonix is literally a magical product that has helped me so much already and I will be using this for a long time coming.
Sonix is faster and better than YouTube at making captions for my videos!
I've used other platforms that don't do a good job at all. Sonix was close to perfect!
AMAZING!! Seamless. Quick. Very accurate. Easy to use. Time stitching. The ease of assigning speakers to paragraphs and making new paragraphs are all amazing!
I need to produce very accurate transcripts and the initial transcripts Sonix produces are much better than competitors (I've used many others).
