Your product is amazing and transcribed my files almost all accurately!
Very cool and fascinating too. Ahh the power of algorithms. I can tell you that I love the overall UI experience because it's pretty, dumbed down, and very easy for me to use. I've done a lot of radio and this service would be invaluable for that kind of work.
I love the software and it makes my life so much easier...you cannot believe!
Faster than my captioning department and so easy to create subtitles!
Your UI and UX was one of the best I've seen. And I've seen a lot of them. Clean, simple, and pretty easy to edit.
I’ve now used Sonix.ai twice, and find the service simple and accurate. It’s exactly what I’ve been looking for to get text from audio and video recordings.
I have tested your product among others, and I have to say, Sonix provides the best results, a really great product!!!
I love Sonix.ai. They're fast and clean in transcription; they give 98% accuracy in your transcript. I enjoy every of my experience with Sonix...
