Why users love Sonix
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.
What a great transcript experience! I love the work they are doing at Sonix. Their webpage is really simple to use and yet you get everything you need... most of the time there is very little to no editing on the final text.
Very impressed of your product. The general concept is ingenious for the task to be accomplished and the implementation is impressive. Your product gives great sat...
AMAZING!! Seamless. Quick. Very accurate. Easy to use. Time stitching. The ease of assigning speakers to paragraphs and making new paragraphs are all amazing!
Way better than other transcription services I've tried. It will save me a lot of time. I'd recommend it to everyone I know.
I have a 30-40 minute commute to work and like to dictate memos and other brief documents along the way–but I haven't had an easy way to get them transcribed...until now. Thanks Sonix!
Seriously the best transcript I’ve ever seen. And the synchronized editor is amazing. I will be using again and I will be sharing with my friends :)
The process was super easy. I liked that you can upload video file without stripping away the audio first to do it, this of course saves production time. Great job overall for sure!!!
