Fast and easy, and accurate. And searchable.
Wow very cool. Sonix is so awesome. There will be huge demand for this. The editor will be really good for team sharing. Such a great platform.
Researched and did trials of at least 12 other services. Chose Sonix because of accuracy and simplicity.
Gobsmackingly amazing! As a software developer of 40 years I know quality when I see it. An amazing product and a pretty damn good web-site to back it all up also. Totally staggered at the accuracy, especially when multiple voices contribute to a meeting.
I absolutely loved how well the software was able to distinguish between individual speakers. Exceptional product and well-polished.
