Why users love Sonix
It's simply an amazing resource for anyone working with the spoken or written word.
Your transcription tool is amazing. It's easy to use and gave me a great result.
Very high accuracy transcription with noisy tapes / accents. The ability to edit as you listen is incredible. I haven't been impressed with code to this extent sin...
I am LOVING Sonix! The price, accuracy, create your own library, check marks when something is completed. I am so glad I found the service.
The UI experience is fantastic! It's quick and easy to understand. Plus it's web based so I can switch between my desktop and laptop easily.
Easy to use and saved me mega amounts of time!
The recording I transcribed was poor quality at best, so I was pleasantly surprised by how accurately Sonix captured the text. And your editor is absolutely brilliant!
It's incredibly fast, and it sets the timing for subtitles perfectly. I dread having to time everything myself, and with Sonix I can do that just by pressing Enter!
